About Fundraise Up

We’re Fundraise Up - a global fundraising platform built to make donating to nonprofits fast, seamless, and accessible to all. Every month, our technology powers tens of millions of dollars in donations across the globe. We focus on innovation that directly impacts results: faster load times, higher conversion rates, global payment support, and accessibility-first design.

Our platform is trusted by many of the world’s leading nonprofits, including UNICEF, the Alzheimer’s Association, and a wide range of global NGOs. With a 4.9/5 rating across top software review platforms, we’re recognized not just for our impact - but for the quality of the product we deliver.

A Truly Global Product

We operate in the enterprise segment, serving nonprofit organizations across North America, the United Kingdom, Australia, and Europe.

We’re building a large and complex product ecosystem that serves nonprofits, donors, and partners around the world. The platform includes a modern checkout experience and customizable widgets (each a standalone SPA), donor, organization, and partner portals, admin tools, and several internal apps.

Our backend is powered by Node.js (Koa, NestJS) and MongoDB. The frontend stack includes Webpack, Vue.js, and React, with nearly all code written in TypeScript. For high-throughput messaging and background processing, we use Kafka (for millions of events) and Bull (Redis). Analytics data is stored in ClickHouse, and we use Elasticsearch for search.

The Team

We are a distributed team of 160+ product professionals, including 80+ engineers. Our team members are mainly based across Spain, Poland, Portugal, Georgia, Armenia, Serbia, Turkey, and Cyprus. Many of our developers bring 5 - 10+ years of experience, and we foster a culture of deep technical curiosity and knowledge sharing.

Despite our scale, we operate like a focused team - where every task matters and every voice is heard. We value thoughtful collaboration, strong engineering practices, and a product mindset. You’ll be joining a team where quality, mentorship, and mutual respect come first.

About the Role

We are looking for an experienced Team Lead to join our Elements team. In this role, you will lead the development of embedded "elements" — a suite of widgets that non-profits integrate into their websites to drive donations or display impact statistics. Tech Stack: Node.js, React, TypeScript, MongoDB, Cloudflare Workers, and Kafka.

We already have a strong team of developers as well as a product and technical roadmap in place, but we are missing a strong technical leader to lead the team.

What You'll Do

• Lead a team of 3-5 Fullstack developers.
• Write and review code (approximately 70/30 split in favor of management).
• Ensure the team follows company processes and engineering guidelines.
• Own the delivery of features and adherence to deadlines.
• Make technical decisions, prepare technical designs for new features, and align them with neighboring teams and your manager.
• Manage technical debt and maintain the technical backlog for your team.
• Mentor and develop engineers; conduct regular 1:1 meetings.
• Onboard new team members.
• Conduct performance reviews.

Requirements

• You are an experienced Engineering Team Lead with 10+ years of software development experience, including at least 2 years as a Team Lead or Engineering Manager managing a team of 3–5 developers.
• You’re a hands-on leader who can write code, make sound technical decisions, and design systems thoughtfully.
• You have strong people management skills — hiring, coaching, giving feedback, and resolving conflicts.
• You have at least 3 years of experience as a Fullstack Developer.
• You have at least 5 years of experience in product companies working with our stack: TypeScript, Node.js, MongoDB, Kafka, Redis.
• Experience working in fast-growing companies or startups will be a plus.
• Your English is at B2+ level: you don’t struggle to find words and can confidently discuss any technical topics.

Why work with us

• A strong, collaborative product team that owns what it builds
• Clear product vision and access to real customer feedback from global nonprofit leaders
• Flat structure: no politics, just great work with great people
• Transparent company culture-we share how we’re growing, where revenue comes from, and what’s next
• Long-term focus: we offer equity options and value sustained, meaningful contribution

Benefits

• 31 days off
• 100% paid telemedicine plan
• Home Office Setup Assistance: the company offers assistance with purchasing furniture (office chair, office desk, monitor) and other items to create a comfortable workspace
• English learning courses
• Relevant professional education
• Gym or swimming pool
• Co-working
• Remote working

Each month, people around the world contribute tens of millions of dollars through our platform.

The world’s leading nonprofit organizations trust Fundraise Up. UNICEF, the most prominent UN charity, uses our platform for 100% of its online fundraising. So does the American Heart Association, the Alzheimer’s Association, and many others. We’re proud to maintain a 4.9 out of 5 rating on leading review platforms.

We serve the enterprise segment, with a primary client base in the US, Canada, UK, and Australia.

The Team

Our product development team is currently at 150+ and growing. Team members are located across Spain, Serbia, Poland, Portugal, Turkey, Cyprus, Georgia and Armenia. We primarily communicate in Russian.

It’s a dynamic, collaborative environment where smart, curious engineers support one another, share knowledge, and strive for excellence. We encourage open dialogue and host bi-weekly engineering meetups to explore technical topics and showcase team insights.

About the Role

We’re looking for a Team Lead to join our Product Analytics team for the New Products direction. The New Products direction is our “internal incubator,” responsible for the company’s future revenue. We don’t just improve existing products — we launch entirely new business verticals from scratch.

Currently, we have three key focus areas:
    1.    P2P (Peer-to-Peer): Building tools for mass fundraising events and marathons (a market with $8M+ ARR potential).
    2.    Tap-to-Pay & Kiosks: Enabling offline donations via smartphones and physical terminals.
    3.    Major Donors: Leveraging AI to identify and engage high-value donors.

At the moment, the team consists of one analyst who has already started working on the P2P product.

What You’ll Do

• Act as a right hand to product leads (PMs): help define success criteria for pilots and evaluate whether new products gain traction
• Build analytics from scratch: design data collection systems and ensure reliability monitoring from day one
• Evaluate the performance of new product launches
• Lead and grow the team: mentor team members, run 1:1s, and establish processes in a fast-growing function, as well as plan the roadmap and oversee execution and timelines

Requirements

• 5+ years of experience as a Product Analyst
• 2+ years of team management experience
• Strong knowledge of mathematical statistics and probability theory
• Proficiency in Python (NumPy, pandas, matplotlib, seaborn, scikit-learn)
• Advanced SQL skills
• Experience with BI tools (Tableau, Power BI, Metabase)

Our Tech Stack

• Python
• ClickHouse, MongoDB, PostgreSQL
• Tableau, Grafana
• Airflow
• Git

Bonus points

• Curiosity and a hypothesis-driven mindset
• Ability to communicate complex analytical concepts to non-technical audiences
• Detail-oriented with a strong sense of ownership
• Comfort working in fast-paced, data-rich environments

Why work with us

• A strong, collaborative product team that owns what it builds
• Clear product vision and access to real customer feedback from global nonprofit leaders
• Flat structure: no politics, just great work with great people

About Fundraise Up

We’re Fundraise Up - a global fundraising platform built to make donating to nonprofits fast, seamless, and accessible to all. Every month, our technology powers tens of millions of dollars in donations across the globe. We focus on innovation that directly impacts results: faster load times, higher conversion rates, global payment support, and accessibility-first design.

Our platform is trusted by many of the world’s leading nonprofits, including UNICEF, the Alzheimer’s Association, and a wide range of global NGOs. With a 4.9/5 rating across top software review platforms, we’re recognized not just for our impact - but for the quality of the product we deliver.

About the Role

This role is the primary owner of how the product team operates. You ensure quality and velocity don't trade off against each other — by building, scaling, and protecting the processes that make good product decisions repeatable.

You'll report directly to the CPO and serve as the main entry point for new Product Ops initiatives — prioritizing, routing, and leading the ones that matter most. You focus on what scales across the whole product team, not what solves a one-off problem for one squad.

The Product Ops team is two people: you and one manager — with plans to grow. This is a genuinely hands-on role — you'll be doing real work, not just directing it. Expect to own processes end-to-end, from design through adoption.

What You'll Own

• Be the primary entry point for new Product Ops initiatives — prioritize them, decide what gets resourced, and route what doesn't fit.
• Lead major cross-team process changes: design the frame, align stakeholders, and drive adoption.
• Own cross-team processes across the Product department (Product, Design, and Analytics) where central coordination is required — quarterly planning, goal decomposition, metrics alignment.
• Build and maintain shared frameworks and artifacts (prioritization logic, metrics models, decision templates) that improve clarity and consistency across the product team.
• Identify and escalate systemic process problems that require cross-team or leadership-level decisions.
• Drive AI automation of product workflows — identify high-leverage opportunities, build or oversee solutions, measure against baselines, and decide what scales across the team.
• Manage Product Ops focus and load: ensure the team works on things that move the needle, not reactive noise.

What Success Looks Like

• Product Ops initiatives have a transparent, understood focus — no one wonders what the function is for.
• Shared processes are adopted and used consistently across product teams (measured by adoption rate and CSAT).
• Operational noise decreases — fewer ad-hoc requests, less manual coordination, fewer alignment gaps.
• Product decisions become more predictable and higher quality — even as the company keeps scaling fast.

What We're Looking For

• Process design experience. You've built or significantly improved operational processes in a product or tech environment. You think in systems, not tasks.
• Cross-functional influence. You know how to align people who don't report to you. You bring clarity to ambiguous situations and can drive decisions across teams.
• Metrics-driven. You track adoption and satisfaction as seriously as any product team tracks conversion. You know how to set a baseline and measure change.
• Bias toward scalability. You distinguish between fixing a one-off problem and building something the whole team can use. When both paths are possible, you ask: will this still work when the team doubles?
• Full ownership of your domain. You take accountability for outcomes, not just tasks. Blockers are your problem to solve — not someone else's.
• AI automation fluency. You've used AI tools to automate workflows or processes — and you can identify where automation creates real leverage vs. where it's noise.
• Fluent English (C1+). We're a mixed company — the product team works in Russian, but you'll have English-language meetings daily and work with English documentation constantly.

Bonus Points

• Product fluency — you understand how product teams work: discovery, prioritization, planning cycles, roadmap trade-offs
• Background in product operations or program management
• Familiarity with OKR frameworks, quarterly planning processes, or company-wide goal alignment
• Comfortable working in a fast-scaling environment without a defined playbook for everything

Benefits

Our compensation package includes comprehensive benefits and perks, meaningful equity, and a competitive salary:

• 31 days of paid time off
• 100% paid telemedicine plan
• Home office setup assistance
• English learning courses
• Professional education budget
• Gym or swimming pool membership
• Co-working support
• Fully remote work

Highlights

• Location: Turkey, Remote (CET)

• Language: Russian-speaking team; English fluency required (C1)

About the Role

You will act as the "Architect of Execution" in a high-velocity environment: Checkout is the primary surface where the vast majority of our growth experiments are deployed. You will manage the intersection of strategic roadmap initiatives, high-frequency experimentation (in direct partnership with our PM Growth), and critical GTM support. If you are a seasoned product leader who thrives when the stakes are high, and precision is non-negotiable, we want to hear from you.

What You’ll Own

• Product Vision & Strategy: Define the long-term roadmap for Checkout Modal and align it with company OKRs.
• Revenue Engine Integrity: Take full ownership of the Checkout Modal's performance, stability, and evolution, ensuring it remains a world-class donation experience.

What You’ll Do

• Execute Strategic Roadmap: Translate company-wide strategic initiatives into prioritized, actionable plans and lead their delivery.
• Drive Growth Velocity: Partner directly with PM Growth to execute high-frequency experiments. You lead the technical specification and delivery phase, ensuring high-speed deployment without compromising platform stability.
• Orchestrate Stakeholders: Coordinate across multiple product areas and support GTM teams in resolving enterprise-critical deal breakers.
• Ensure Quality & Scalability: Collaborate with engineering to drive internal improvements, reduce tech debt, and maintain world-class performance.

What You’ll Need

• 5+ years of experience in Product Management within a B2B SaaS or Fintech environment.
• Senior Product Stewardship: Proven track record of managing a high-traffic, revenue-critical product surface.
• Strategic & Execution Mindset: Ability to balance independent roadmap ownership with a collaborative, execution-partner approach for Growth initiatives.

• Technical Communication: Ability to translate abstract business goals into clear requirements for engineering.
• Fluency in English (C1): Excellent verbal and written communication skills.

Benefits

Our compensation package includes comprehensive benefits and perks, meaningful equity, and a competitive salary:

• 31 days off
• 100% paid telemedicine plan

• Relevant professional education.
• Gym or swimming pool.
• Co-working.

Your day-to-day responsibilities will include designing, developing, and delivering new features, as well as unblocking and mentoring your teammates. Your work will generally focus on the lower level features and optimizations.

This role has both an internal and external focus, your contributions will make a meaningful difference in the day-to-day lives of your peers at Sezzle, enhancing their ability to support our business and customers, and you will have opportunities to take any feedback and iterate.

What You'll Do:

• Architect, design, and build scalable backend services and APIs primarily in Golang, leveraging AWS, RDS (MySQL/Postgres), and modern distributed patterns.
• Lead Sezzle’s AI enablement efforts, identifying opportunities to apply AI and automation to enhance developer productivity, internal tooling, and customer experiences.
• Partner with teams across the organization to integrate modern AI capabilities - Primarily around tools like Claude Code, Codex, Cursor and enhancing team productivity.
• Drive consistency and scalability across a distributed microservices architecture while maintaining performance and reliability.
• Establish and evolve engineering best practices for observability, security, and CI/CD across teams.
• Mentor engineers and champion a culture of learning, innovation, and operational excellence.
• Collaborate cross-functionally to translate business goals into technical roadmaps and deliver results that matter.

What We Look For:

• 12+ years of professional software engineering experience, including significant backend experience.
• Deployed significant changes to a production application in the past 30 days.
• Strong proficiency in Golang, with experience building and maintaining RESTful APIs.
• Expertise with SQL-based RDBMS (MySQL, PostgreSQL) and experience optimizing schema and queries for performance at scale.
• Solid understanding of distributed systems design patterns (e.g., transactional outbox, event-driven architecture, queues).
• Demonstrated ability to bring new ideas forward, influence decisions, and lead complex technical initiatives.
• Bachelor’s degree in Computer Science or equivalent practical experience.

Preferred Knowledge and Skills:

• Proficiency in observability tools (Prometheus, Grafana, Datadog, New Relic).
• Experience with AWS cloud infrastructure, mainly AWS Aurora RDS, both MySQL and Postgres.
• Experience in fintech, payments, BNPL, or consumer lending - familiarity with financial compliance, credit decisioning, or transaction processing systems.
• Experience with CI/CD pipelines and containerized microservices (Docker, Kubernetes).
• Working knowledge of TypeScript, React, or React Native.
• Familiarity with AI/ML tooling (e.g., OpenAI API, LangChain, Hugging Face, or custom LLM integrations).
• Track record of shipping commercial APIs and data-driven applications in high-growth environments.
• Proven leadership in guiding technical direction, improving system reliability, and scaling engineering organizations.

About You: 

• You have relentlessly high standards - many people may think your standards are unreasonably high. You are continually raising the bar and driving those around you to deliver great results. You make sure that defects do not get sent down the line and that problems are fixed so they stay fixed.
• You’re not bound by convention - your success—and much of the fun—lies in developing new ways to do things
• You need action - speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk-taking.
• You earn trust - you listen attentively, speak candidly, and treat others respectfully.
• You have backbone; disagree, then commit - you can respectfully challenge decisions when you disagree, even when doing so is uncomfortable or exhausting. You have conviction and are tenacious. You do not compromise for the sake of social cohesion. Once a decision is determined, you commit wholly.
• You deliver results - you focus on the key inputs and deliver them with the right quality and in a timely fashion. Despite setbacks, you rise to the occasion and never settle.

We’re not just transforming payments; we’re redefining how people discover, interact with, and purchase the things they love while driving real impact on merchant sales through increased conversions and higher order values. As we continue to shape the future of fintech and retail, we’re building an innovative, dynamic team passionate about creating more than just a transaction but a truly unique shopping journey. If you’re excited about pushing boundaries in tech and delivering a game-changing experience for consumers and merchants alike, come join us at Sezzle and help create the future of shopping!

About the Role: 

We are seeking a talented and motivated Senior Software Engineer with accounting and financial experience. This role offers an exciting opportunity to thrive in a dynamic, fast-paced environment within a rapidly growing team, with abundant prospects for leadership and innovation.

This position is ideal for professionals who began their careers in accounting or finance and later transitioned into software engineering — individuals who now want to leverage that domain expertise to architect and scale technical solutions that solve complex financial challenges in fintech.

As a Senior Software Engineer, you will design, develop, and optimize high-impact systems that power Sezzle’s financial reporting, reconciliation, and automation workflows. You’ll partner closely with cross-functional teams — including Accounting and Finance — to ensure data integrity, streamline financial processes, and build robust, auditable systems that meet enterprise-grade standards.

Your role will extend beyond development. You’ll mentor engineers, shape technical direction, and bring a strong sense of ownership to every project you lead. You should be able to build high-quality, innovative, and fully performing software in compliance with coding standards, technical design, and regulatory best practices.

Compensation:

For this senior development role, with 8+ years of experience, the compensation range is $5,000 - $9,500 USD per month. This range acknowledges the extensive expertise, leadership capabilities, and significant contributions expected at this level, offering a competitive salary to reflect the value of advanced skills and experience.

• Familiarity with containerized micro-service architecture deployed with Kubernetes on AWS
• Demonstrated history of delivering commercial APIs and web applications

About You: 

• You have relentlessly high standards - many people may think your standards are unreasonably high. You are continually raising the bar and driving those around you to deliver great results. You make sure that defects do not get sent down the line and that problems are fixed so they stay fixed.
• You’re not bound by convention - your success—and much of the fun—lies in developing new ways to do things
• You need action - speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk-taking.
• You earn trust - you listen attentively, speak candidly, and treat others respectfully.
• You have backbone; disagree, then commit - you can respectfully challenge decisions when you disagree, even when doing so is uncomfortable or exhausting. You have conviction and are tenacious. You do not compromise for the sake of social cohesion. Once a decision is determined, you commit wholly.
• You deliver results - you focus on the key inputs and deliver them with the right quality and in a timely fashion. Despite setbacks, you rise to the occasion and never settle.

• Lead efforts to implement and improve dependency and container supply chain risk detection systems and controls
• Partner closely with engineering teams to remediate vulnerabilities and improve secure development and deployment practices
• Support and implement security controls aligned with PCI DSS, SOC 2, and other compliance requirements
• Develop and implement automation (including AI where appropriate) to improve efficiency in security operations, detection, and response
• Triage and validate external security findings, distinguishing true positives and coordinating remediation

What We Look For: 

• 6+ years of experience in security, software, or infrastructure engineering, with hands-on experience securing cloud-based production systems and working with real-world security challenges
• Experience contributing to threat modeling and security design reviews for modern systems
• Strong hands-on experience in vulnerability management, including scanning, triage, validation, remediation coordination, and verification
• Experience working with SIEM platforms (e.g., Wazuh, Splunk, ELK) for detection engineering, monitoring, and incident response
• Practical experience triaging findings from vulnerability scanners and bug bounty programs
• Strong knowledge of AWS, Linux, and Kubernetes infrastructure, including security architecture, hardening, and operational best practices
• Experience improving infrastructure security, including CI/CD hardening and mitigating software supply chain risks
• Experience with container and dependency security tools (e.g., Snyk, Trivy, Grype, etc.)
• Ability to investigate issues directly using logs, cloud tooling, and system-level data
• Knowledge of common security vulnerabilities and mitigation strategies (OWASP, SANS, etc.)
• Working knowledge of compliance frameworks such as PCI DSS and SOC 2

Preferred Knowledge and Skills:

• Experience designing and tuning detection rules, reducing alert noise, and improving investigation workflows
• Strong understanding of cloud-native security controls, including IAM, network segmentation, and container security
• Familiarity with log-based detection, telemetry pipelines, and security analytics use cases
• Experience designing secure CI/CD workflows that reduce exposure to vulnerable dependencies and untrusted artifacts
• Ability to assess application and infrastructure risk and translate findings into actionable improvements
• Experience aligning technical security work with regulatory and compliance expectations
• Experience using automation and AI to reduce manual effort and improve consistency at scale

About You: 

• You think proactively about security and work to address risk early through clear design feedback and practical engineering solutions
• You bring strong cloud and infrastructure judgment, especially in AWS and Kubernetes environments
• You raise the bar on hardening and operational discipline, especially in CI/CD and supply chain security practices
• You approach security monitoring with an investigator’s mindset and can turn telemetry into meaningful detection and response outcomes
• You are excited to use automation and emerging technologies (including AI) to automate repetitive security work and improve team effectiveness
• You balance strong security standards with business needs and can support privacy and compliance requirements in a practical, scalable way
• You have relentlessly high standards - many people may think your standards are unreasonably high. You are continually raising the bar and driving those around you to deliver great results. You make sure that defects do not get sent down the line and that problems are fixed so they stay fixed.
• You’re not bound by convention - your success—and much of the fun—lies in developing new ways to do things
• You need action - speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk-taking.
• You earn trust - you listen attentively, speak candidly, and treat others respectfully.
• You have backbone; disagree, then commit - you can respectfully challenge decisions when you disagree, even when doing so is uncomfortable or exhausting. You have conviction and are tenacious. You do not compromise for the sake of social cohesion. Once a decision is determined, you commit wholly.
• You deliver results - you focus on the key inputs and deliver them with the right quality and in a timely fashion. Despite setbacks, you rise to the occasion and never settle.

About the Role: 

We are seeking a hands-on, high-impact Senior Security Infrastructure Engineer to help strengthen Sezzle’s security posture across cloud infrastructure, applications, and developer workflows. This role is ideal for someone who thrives in a fast-paced environment and wants to work on real-world security problems at scale.

As a Senior Security Infrastructure Engineer, you will have a high degree of ownership and autonomy to identify risks, investigate issues, and drive meaningful security improvements across our systems. You will work across vulnerability management, detection engineering, supply chain security, and incident response - partnering closely with engineering teams to ensure security is practical, effective, and embedded into how we build and operate systems. You should consider yourself a DOer - someone who is comfortable diving into logs, analyzing systems, validating findings, and working end-to-end to get issues resolved. We value engineers who bring strong technical depth, good judgment, and the ability to turn security insights into actionable outcomes.

This role offers the opportunity to shape and scale security capabilities, including detection systems, supply chain risk controls, and security automation. With the support of modern tooling (including AI where appropriate), you will play a key role in improving efficiency, visibility, and resilience across the organization. This role combines hands-on security operations with exploratory and design work. You will spend significant time investigating and resolving real-world issues, while also researching, evaluating, and building new security capabilities across areas like detection, supply chain security, and data protection.

• Lead and operate vulnerability management across infrastructure, platforms, and applications - including internal scans, dependency analysis, and external findings, validating true positives and driving remediation with engineering teams
• Build, operate, and mature SIEM/XDR capabilities, including log ingestion, detection rule development, alert tuning, and investigation workflows
• Investigate and respond to security incidents across cloud infrastructure and applications, performing root cause analysis and driving long-term fixes
• Design and implement detection strategies for suspicious activity, including data exfiltration patterns using application and database telemetry
• Lead and contribute to threat modeling exercises and security design reviews to identify risks early and strengthen architecture
• Apply deep expertise in AWS and Kubernetes to design, secure, and improve resilient and secure cloud infrastructure at scale
• Drive infrastructure and CI/CD hardening initiatives, with a focus on reducing software and container supply chain risk
• Lead efforts to implement and improve dependency and container supply chain risk detection systems and controls
• Partner closely with engineering teams to remediate vulnerabilities and improve secure development and deployment practices
