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
You will join a small team responsible for the stability, performance, and security of our server infrastructure: bare metal, VMs, databases, queues, networking, and infrastructure security. Our philosophy is simple: the team owns its systems end-to-end, and every engineer should be able to diagnose and fix issues in their area of responsibility.
This role is for someone who enjoys working with real infrastructure (OS, hardware/virtualization, networks), not just cloud abstractions.
What You'll Do
- Work primarily with on‑premise infrastructure (bare metal and VMs): setup, maintenance, troubleshooting
- Drive clarity in ambiguous situations by defining requirements, assumptions, and next steps
- Own automation projects end‑to‑end (design → rollout → maintenance)
- Improve how we operate: harden and tune systems and also improve the way the team works in terms of operational hygiene
- Keep the platform stable, fast, and secure: servers, web servers, databases, queues
- Investigate production incidents across OS / networking / infrastructure layers, apply temporary mitigations, coordinate with developers and participate in post‑mortems
- Participate in on‑call rotations
- Use AI in all aspects of day‑to‑day work: researching, troubleshooting, developing
Requirements
- 4+ years as a DevOps Engineer / SRE (or very close responsibilities)
- Real, hands-on experience with servers (VMs, bare metal) at the OS level and below: configuring, troubleshooting, digging into “why it’s broken”
- Confident Linux skills (we use Ubuntu). We expect you to be comfortable with the core tools from Linux Crisis Tools
- Solid understanding of networking basics; ability to configure and troubleshoot iptables
- Ansible + Git
- Experience with Bash or Python scripting for automation/observability
- Production/on‑call experience: diagnosing incidents, restoring service, participating in post‑mortems
- Ownership and attention to detail. Downtime is expensive: five years ago, 10 minutes of downtime cost us $100k — today it’s even more
Nice to Have
We understand it’s impossible to be an expert in everything, but it’s important to have solid hands-on experience in two or more of the areas below:
- ClickHouse, MongoDB: what each database is used for, monitoring, troubleshooting performance and slow queries, sharding
- Kafka: operating clusters at scale (topic moves, broker replacements, tuning)
- Redis: high‑load tuning, replication, sharding, performance monitoring
- Elasticsearch: configuration, scaling, sharding/cluster management
- HAProxy / Nginx: load balancing, SSL/TLS, caching, reverse proxying, performance monitoring
- OS tuning: kernel/network stack/filesystem parameters for high‑load systems
- Full Disk Encryption on LVM: We use Clevis + Tang in production
- Infrastructure Security: Teleport, HashiCorp Vault
Bonus points
Great if you’ve worked with any of the following:
- VictoriaMetrics and how it differs from the Prometheus stack
- Complex CI/CD pipelines. We use scripted Jenkins pipelines
- Bare‑metal Kubernetes: provisioning, networking (MetalLB or alternatives), isolation from the internet, scaling across providers (like OVH, Hetzner) and integration with existing infrastructure
- Flux and GitOps
- Terraform
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.

- Architectural Mindset: A strong understanding of system design, clean architecture principles, and performance optimization.
- Ownership: The ability to work independently, take ownership of your work, and see projects through to completion.
- Communication: Comfortable working within a Russian-speaking team.
Nice to Have
- Prior experience working in a remote-first, globally distributed team.
- Experience with performance monitoring and observability tools (e.g., Prometheus, Grafana, Datadog).
- A genuine interest in the non-profit technology sector.
- A hypothesis-driven mindset and the ability to communicate complex technical concepts to non-technical stakeholders.
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

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. Biweekly engineering forums give space to share learnings and celebrate technical achievements. You’ll be joining a team where quality, mentorship, and mutual respect come first.
About the role
As Director of Product, Core Markets, you will own the strategy and execution that positions Fundraise Up as the category leader in key nonprofit verticals. You’ll lead and grow a team of Product Managers, collaborate tightly with Sales, GTM, and Customer Success, and engage directly with senior nonprofit executives on complex, enterprise-scale deals. This is a hands-on, results-driven role — you will set bold vision, raise the bar on execution, and drive measurable revenue growth and market dominance.
What “Core Markets” means here
Core Markets represent the priority verticals where Fundraise Up has established strong traction and significant growth potential — including large Tier 1 & Tier 2 nonprofits across Cause & Cure, Faith-based, and adjacent segments. Your mandate: position Fundraise Up as the partner of choice and default platform within these key markets.
Key Responsibilities
Market & Customer Leadership
- Develop deep expertise in Core Markets — understand segments, buying behaviors, procurement and RFP patterns, compliance requirements, and the key barriers to adoption.
- Drive continuous discovery — conduct executive interviews, site visits, and industry events, translating insights into clear “must-haves” versus differentiators for each vertical.
- Own strategic enterprise deals — present the product vision, address objections, and collaborate with the Go-to-Market team to co-create scalable, enterprise-grade rollout plans.
Portfolio Strategy & Outcomes
- Define and own the Core Markets strategy and multi-quarter roadmap across verticals; articulate crisp bets with quantified business cases.
- Balance scale vs. customization: protect product integrity while unlocking enterprise wins (no “zoo” of one-offs).
- Set and deliver against OKRs that tie directly to revenue and adoption (ARR growth, win-rate, NRR, adoption of key capabilities).
Team Leadership
- Hire, mentor, and inspire 2–5 PMs (vertical leads). Build a culture of ownership, curiosity, and high accountability.
- Establish operating rituals (discovery cadence, metrics reviews, launch playbooks) that scale learning and delivery.
- Grow leaders: coach PMs to manage their own cross-functional pods and represent the product credibly with enterprise customers.
GTM & Cross-Functional Partnership
- Operate as a true partner to Sales, Solutions, CS, and Marketing: equip teams with product narratives, competitive angles, and clear boundaries.
- Lead cross-functional execution with Engineering, Design, and Analytics to ship impactful, reliable capabilities on time.
- Communicate trade-offs with executive clarity; make decisions, document rationale, and keep stakeholders aligned.
Skills and Qualifications
- 10+ years in Product Management, with 3+ years leading PMs (managing managers or multiple PMs across areas).
- Enterprise B2B experience (SaaS/fintech/payments/e-commerce or adjacent), including pre-sales/RFPs and complex stakeholder management.
- Proven discovery & execution track record: from insight → business case → delivery → measurable impact.
- Metrics fluency: ARR, NRR, win-rate, conversion, adoption, time-to-value; strong analytical and decision-making skills.
- Communication: C1/C2 English—clear, confident, and persuasive with executives and cross-functional teams.
- Travel-ready: comfortable with regular customer visits and conferences (including the U.S.).
Bonus points
- Experience in nonprofit, giving, or payments (compliance, risk, donor experience).
- History of building vertical toolkits/solutions that scale across enterprise accounts.

Compensation: €6,800 - €8,000 gross + stock options
Language: Russian-speaking team; English B2+ required
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

The Role — Interstellar Squad
The Interstellar Squad owns a core part of our commercial platform: the billing run — a mission-critical, high-volume pipeline that turns large-scale usage data into timely, accurate invoices for customers worldwide. It's a technically rich domain: distributed data processing, event-driven workflows, financial correctness, and operational reliability at scale.
We're looking for a Staff Software Engineer to set the technical direction for Interstellar, raise the engineering bar across the squad, and guide delivery of a platform that has to stay correct, predictable and scalable as the business grows.
A central part of this role is leading the gradual modernisation of a mature platform into a set of focused, TypeScript-based domain services — using a strangler-fig approach to extract capabilities incrementally, keeping the existing system safe and our customers unaffected while we evolve the architecture.
You'll report to an Engineering Manager and partner closely with the Product Manager, Delivery Manager and engineers in the squad, as well as peer Leads across the domain. You'll have the mandate to shape how we design, build and run our systems — and the responsibility to keep the team aligned behind that direction.
This role is based in Poland to work alongside the rest of the squad.
Key Responsibilities
- Set and communicate a clear technical vision for the squad's services, aligned with product and business objectives, and translate it into concrete near-term work
- Lead the incremental decomposition of a mature platform into well-bounded, TypeScript / Node domain services using a strangler-fig pattern — defining seams, sequencing extractions, and protecting delivery and correctness throughout
- Define and uphold engineering standards for code quality, testing, observability, and operational readiness across the squad — applied consistently to both legacy and new services
- Own complex technical decisions end-to-end: articulate trade-offs, choose an approach, document it, and bring the team along
- Drive architecture and system design for distributed, data-intensive billing workflows — simplifying where we can, investing where it pays off
- Lead the design and implementation of SLIs and SLOs for squad-owned services (Grafana), and take ownership of their health and reliability in production
- Guide CI/CD and delivery practices in collaboration with the squad (GitLab), keeping cycle time short and releases safe across both old and new components
- Raise the bar on code review — provide thorough, growth-focused feedback and coach engineers to do the same
- Mentor engineers at all levels, create clear growth paths and unblock them day to day; help the team build confidence in modern TypeScript/Node practices
- Champion AI-assisted/agentic engineering (IDE agents, CLI tooling, reviews) — set norms for when and how to use it, keep humans accountable for correctness, and share practices with peer squads
- Partner with Product and Delivery to shape roadmaps, size work honestly and manage technical debt with intent
- Represent the squad in cross-domain technical forums and contribute to the wider engineering direction
Key Experience & Skills
Required
- Proven experience leading the technical direction of a squad or product area, not only as an individual contributor
- Deep, production-proven backend expertise in a modern, strongly-typed stack — ideally Node.js / NestJS / TypeScript and/or PHP 8.x / Symfony
- Demonstrable experience modernising or decomposing a mature monolithic / legacy system into smaller services — comfortable with strangler-fig, anti-corruption layers, contract design, dual-write / shadow strategies, and incremental cut-overs
- Strong background in distributed systems and event-driven / asynchronous processing (e.g. RabbitMQ, Kafka, SQS)
- Experience designing and operating data-intensive, business-critical services where correctness, idempotency and recoverability matter
- Strong command of PostgreSQL (query design, indexing, performance tuning); bonus for distributed/sharded setups (e.g. Citus)
- Experience owning CI/CD pipelines and release strategy in a team setting (GitLab or equivalent)
- Track record of defining and enforcing engineering standards — type safety, clean architecture, testing, observability
- Practical experience with observability and SLO-driven operation of production services (metrics, tracing, logs; Grafana or similar)
- Strong communication and stakeholder skills: can explain trade-offs to engineers, PMs and senior leadership clearly and honestly
- Experience mentoring engineers and developing them over time
- Sensible, hands-on exposure to AI-assisted development (e.g. Cursor, Claude Code, GitHub Copilot or similar) with a thoughtful view on where it helps, where it doesn't, and how to use it safely in a team context
Preferred
- Experience leading a PHP → TypeScript / Node transition (or equivalent cross-language modernisation)
- Strong understanding of TypeScript at an architectural level: generics, decorators, dependency injection patterns and type system design
- Experience with PHP / Symfony monorepos and shared library patterns
- Background in billing, financial or metering/rating domains
- Familiarity with AWS-based platforms (ECS, S3, Parameter Store, SES)
- Experience evolving a team from an IT-delivery mindset toward a Product Operating Model
- Exposure to projects involving LLMs or Machine Learning in a production context
What Will Make You Shine at Wireless Logic
- Leads with technical credibility — brings architectural confidence without becoming a bottleneck
- Creates clarity — turns ambiguous domain problems into simple, well-structured decisions
- Modernises pragmatically — knows when to extract a service, when to leave it, and how to keep the lights on while the architecture evolves
- Executes through the team — balances writing code with enabling engineers to do their best work
- Manages delivery pragmatically — breaks down problems, sequences work, communicates progress and risk early
- Manages technical debt with intent — makes informed, defensible calls about when to refactor
- Partners with Product — translates business outcomes into technical plans and back again
- Coaches and grows people — gives direct, kind feedback and invests in the team's development
- Models continuous learning — including thoughtful adoption of new tooling and AI-assisted workflows
Why Come Work with Us?
- The chance to join a creative, entrepreneurial company where bold ideas are celebrated
- Full training, ongoing support, and the tools to help you thrive and grow in your role
- A company with heart — we genuinely care about our people and make sure everyone feels valued, respected, and part of the team
