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.

About the Role: 

We are seeking a technically strong, hands-on Senior Database Reliability Engineer to help design, build, and scale the database platform used across Sezzle’s applications.

This is not a traditional DBA role. This role is for an engineer who can combine deep database knowledge with software engineering, infrastructure engineering, and platform thinking. You will help build the systems, libraries, automation, standards, and guardrails that make database usage across Sezzle reliable, secure, scalable, and easy for developers to adopt correctly.

As a Senior Database Reliability Engineer, you will be responsible for improving how Sezzle applications connect to, migrate, operate, observe, and scale their databases. You will work across application teams, infrastructure, security, and engineering leadership to define patterns that improve database reliability by design — not just by operational response.

You should be comfortable owning problems end-to-end: understanding application behavior, reading code, reviewing database access patterns, building shared tooling, improving connection management, designing migration safety checks, analyzing production performance, and helping developers use databases in safer and more scalable ways.

You should consider yourself a DOer to be a good fit for this role. We are looking for someone who can ship production-quality engineering work, not just advise from the sidelines. With AI tooling and automation, you should be a force multiplier for database reliability, developer productivity, and operational excellence across Sezzle.

Compensation:

For this senior development role, with 6+ 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.

What You'll Do:

• Design, build, and maintain shared database platform components used by Sezzle applications, such as database connection packages, database client libraries, migration tooling, safety checks, query standards, and developer-facing abstractions.
• Establish reliable, scalable patterns for how Sezzle services connect to and interact with relational databases across production, staging, and development environments.
• Partner with backend engineering teams to improve database usage in application code, including connection lifecycle, transaction handling, retries, timeouts, pooling, query patterns, and migration workflows.
• Build automation and internal tooling that makes database operations safer, more repeatable, and less dependent on manual intervention.
• Define and enforce engineering standards for database access, schema design, migrations, indexing, query performance, connection management, and operational readiness.
• Architect and improve database infrastructure across AWS RDS/Aurora MySQL, PostgreSQL, RDS Proxy, read replicas, backups, failover, parameter groups, monitoring, and capacity planning.
• Lead database reliability initiatives that reduce operational risk, improve performance, and help Sezzle scale safely.
• Review application designs and database changes early in the development lifecycle to ensure reliability, scalability, maintainability, and security are built in from the start.
• Build guardrails for database migrations, including automated checks, rollback expectations, schema review workflows, migration observability, and production safety controls.
• Improve developer self-service for database provisioning, access, schema management, local development, testing, and observability.
• Investigate production database issues by combining application telemetry, database metrics, logs, query plans, traces, and cloud infrastructure data.
• Identify and fix systemic database problems, not just symptoms — including bad access patterns, unsafe migrations, inefficient queries, connection storms, lock contention, replication lag, and capacity bottlenecks.

#LI-Remote

Why You'll Love This Role: 

We're hiring a Senior Software Engineer Contractor for the Writing product team. This is a hands-on role on a small, full-stack team building AI-powered learning experiences. You'll ship across the product end-to-end: frontend, backend, data, and the LLM-driven services that sit behind our assessment features.

We work AI-native. Coding agents (Claude Code, Copilot, Cursor) are how this team builds, reviews, and operates, and we expect senior engineers to do more than use them. The strongest people on the team invest in the harness itself: writing skills, hooks, and custom workflows that make the next person faster.

What We're Looking For:

A Senior Individual Contributor with a high agency. Someone who:

• Owns the full lifecycle. Takes a problem from vague ask to shipped, monitored, and stable in production. Comfortable shaping scope without heavy PM guidance.
• Raises issues early. Catches risks, design drift, and brittle patterns before they reach production - in their own work and in review. Doesn't wait to be asked.
• Picks up slack outside their lane. Steps into incidents, jumps into a teammate's PR queue, and drives an unowned problem when priorities shift.
• Builds in the AI-native space with judgment. Uses agents as a daily driver, knows their failure modes, and pushes the team's practice forward - not just their own.
• Drives delivery. Active in planning and grooming, pushes back on under-specified work, communicates trade-offs clearly to engineering and product partners.

Core Responsibilities

• Ship full-stack features with measurable product impact.
• Provide substantive code review, architectural feedback, not just approvals.
• Serve as a first responder for production issues (within working hours): triage, root cause, and preventive measures recommendations.
• Improve the team's engineering practice over time: tooling, agentic workflows, technical standards, and documentation that lives where work happens.
• Translate product requirements into a technical approach and communicate the reasoning.

Required Experience

• 5+ years building production web applications, with a strong full-stack range (modern React/TypeScript frontends and a typed or Pythonic backend).
• Track record of owning ambiguous problems end-to-end and shipping with measurable impact.
• Substantive code review history - examples of catching architectural issues.
• Active daily use of AI coding agents (Claude Code, Copilot, Cursor, or similar) with a clear point of view on where they help, where they hurt, and how to keep their output reviewable.
• Comfort with production debugging across the stack: traces, logs, profiling, the unglamorous parts.
• Strong async written communication: clear PR descriptions, sharp Slack, sharp specs.

Strong Plus

• Experience extending or building on agentic developer tooling (custom agents, skills, hooks, MCP servers, eval harnesses).
• Background in rich text editing, document collaboration, or LLM-backed product features.

All offers of employment are contingent upon the successful completion of a background check as part of our pre-employment process.

Please note that given the nature of the contract, this role will not be eligible to participate in company-sponsored benefits.

Why Topsort? Why now?

Joining us now, you'll work directly alongside our co-founders and founding members to bring on Retail Media 3.0.

What it’s like to work at Topsort

Our team is all about straightforward communication, embracing feedback without taking it personally, and fostering a super collaborative environment. It’s a sports team that’s hyper focused on winning, collaborative internally, and competitive externally - never the other way around.

We thrive on working in the open, lifting each other up, and getting things done with a sense of urgency. We're the kind of team that loves making bold choices, sharing extraordinary opinions, and maintaining a 100 mph pace. No endless meetings here. If it can be built today, we're all about getting it done today.

What is this role like?

We’re looking for a Product Manager to help make Topsort’s platform work in the real world: across APIs, external partners, enterprise customers, and internal teams moving quickly.

This is not a traditional PM role where success comes from owning a roadmap in isolation. You’ll work alongside engineering, GTM, customers, and industry partners to turn ambiguous requirements and external constraints into shipped product outcomes. You should be technical enough to reason about APIs and systems, socially sharp enough to align stakeholders while preserving the integrity of Topsort's product obsession, and hands-on enough to create clarity when the path is messy.

You’ll thrive here if you are a builder, translator, and operator: someone who can sit with engineers to understand what is possible, work with customers and partners to find new problems to solve, and push the right work forward without waiting for perfect information.

In this role, you will:

• Drive Integration Execution: Lead complex integration initiatives between partners, enterprise customers, and internal teams, turning ambiguity into shipped outcomes.
• Translate Between Technical and Business Needs: Work closely with engineering, GTM, and external stakeholders to define requirements, clarify tradeoffs, and ensure technical decisions map to customer and business value.
• Navigate External Dependencies: Manage the reality of partner timelines, customer constraints, API limitations, incomplete documentation, and shifting priorities while keeping momentum.
• Create Clarity Without Over-Process: Build lightweight structure, documentation, and decision-making frameworks that help teams move faster without slowing down execution.
• Influence Decisionmaking: Align engineering, product, business, and external stakeholders around priorities, risks, and execution plans.
• Improve the Integration Experience: Identify recurring friction across customer and partner implementations and help turn one-off learnings into scalable product improvements.

What (we think) you need to be successful

We are looking for outlier candidates who are technical, highly organized, and energized by messy real-world product problems. You do not need to check every box, but you should be able to show that you can create momentum across technical and non-technical teams in a fast-moving environment.

• API & Integration Fluency: Strong understanding of APIs, data flows, technical constraints, and how software systems connect. You do not need to be a former software engineer, but you should be comfortable working directly with engineers.
• Technical Product Judgment: Ability to evaluate tradeoffs, ask strong technical questions, and help teams make practical decisions without needing perfect specs.
• Stakeholder Orchestration: Strong ability to work across engineering, GTM, customers, and external partners, especially when priorities are competing or ownership is unclear.
• Execution Under Ambiguity: Comfort operating in an environment where requirements are incomplete, priorities shift quickly, and external dependencies create uncertainty.
• Customer & Partner-Facing Mindset: Experience working with enterprise customers, partners, or external stakeholders to understand needs, manage expectations, and solve practical implementation challenges.
• Communication & Documentation: Ability to communicate clearly with both technical and non-technical audiences in Advanced/Fluent English, and to create documentation that improves alignment and repeatability.
• Relevant Experience: Experience in B2B SaaS, platform products, integrations, partnerships, solutions engineering, technical customer success, or technical product management is highly valued.
• Onsite Availability: Availability to work onsite 4 days a week at our Boston, São Paulo, or Santiago office.

What We Value

At Topsort, we seek professionals who embody the following qualities to drive our mission forward:

• Deep dive into details: Professionals who are not content with superficial answers and dive deeply into the details to uncover root causes and optimal solutions.
• Team first: A low need for individual recognition, always prioritizing collective results over personal credit.
• You thrive with ambiguity: Exceptional ability to tackle open-ended problems in unstructured environments, turning chaos into structured innovation.
• Adaptability: Willingness to learn, mentor, lead, and follow as the situation demands, fostering growth at all levels.
• Urgency: A disproportionate sense of urgency in execution, while keeping scalability and the creation of replicable processes in mind to ensure long-term success.
• Curiosity: Genuinely curious individuals who can quickly learn difficult concepts and apply them effectively.

Staff PRODUCT ENGINEER (Contract)

Build it. Ship it. Own it.

Location: Argentina, Brazil, Colombia, Chile, Mexico, Dominican Republic, Peru

About Counterpart

Counterpart is an insurtech platform reimagining management and professional liability for the modern workplace. We believe that when businesses lead with clarity and confidence, they become more resilient, more innovative, and better prepared for what's ahead. That's why we built the first Agentic Insurance™ system — where advanced AI and deep insurance expertise come together to proactively assess, mitigate, and manage risk. Backed by A-rated carriers and trusted by brokers nationwide, our platform helps small businesses grow with confidence. Join us in shaping a smarter future, helping businesses Do More With Less Risk®.

The Role

As a Product Engineer at Counterpart, you own problems and drive outcomes. You iron out requirements with stakeholders, partners, and customers. You leverage AI for implementation. You verify the end-to-end result. You iterate until you move the needle.

You run projects with other Product Engineers and AI agents. You know when to delegate to a human, when to delegate to an agent, and when to do it yourself. 

YOU WILL

Own the Problem

• Take accountability for the outcome. 
• Talk directly to your users, stakeholders, and peers to discover the problem. 
• Translate business intents into functional requirements that engineers and agents can build against. Determine where human judgment is non-negotiable and where AI can augment or act autonomously. 
• Own the non-functional technical requirements. Specify the quality bar: performance, scalability, reliability, security, maintainability.

Build with AI

• Write production-quality code across the stack: Python, Django, AWS, React, and PostgreSQL. You are not afraid of any layer.
• Direct agents and review their output with domain depth. Catch what they miss across the functional and non-functional bar: correctness, edge cases, performance, security, testability, readability.
• Evaluate and improve agent output regularly. Track failure modes. Refine the prompts and patterns that lift the quality ceiling over time.
• Run projects that span other Product Engineers and agents. Coordinate work, manage dependencies, and keep things moving without micromanaging.
• Contribute to architectural decisions. Bring options and alternatives, not objections. Know when the elegant solution is the wrong call for a startup moving fast.
• Contribute to and manage the context harness as you build and deliver.

Verify and Iterate

• Surface delivery risks early. Bring solutions, not just problems. Keep your stakeholders informed without turning every risk into a meeting.
• Verify the end-to-end result yourself. Confirm the system does what the requirements say, and that the requirements were right.
• Drive adoption of what you ship. Documentation, enablement, and usage monitoring are part of the job.
• Monitor your services in production. Own the signal. Debug and fix what breaks.
• Participate in support rotations. When users run into issues with what you shipped, you investigate and fix them.
• Iterate until you move the needle. Shipping is not the finish line. Outcome is.

Raise the Bar

• Mentor engineers around you. Give direct, useful feedback. Leave things better than you found them.
• Make deliberate calls on technical debt: when to accumulate it, when to pay it down, when to refactor. Translate trade-offs into language that business leaders can act on.
• Operate to the engineering standards for quality, reliability, and operational excellence.

YOU HAVE

• 10+ years building production web applications across the full stack. The years are the floor, not the bar. What matters is whether you have actually done this: owned a problem end-to-end, written the spec, built the thing, coordinated the work, and shipped it without someone else holding the thread.
• Demonstrated experience gathering requirements directly. You have interviewed users, customers, and partner teams, and turned ambiguous intent into specs that engineers and agents can build against.
• Demonstrated experience owning both functional and non-functional requirements. You have defined what a system must do and held the line on how well it must do it.
• A track record of owning a domain or initiative without close supervision. You have navigated ambiguity, made judgment calls, and been accountable for the outcome.
• Extreme ownership and a bias for action. You do not sit and wait. You chase stakeholders, customers, and answers when you need them.
• Experience coordinating across engineers and AI agents on a shared initiative. You have managed the work without holding a formal management title.
• Strong technical judgment and the depth to catch what AI-generated code gets wrong: not syntax, but correctness, architecture, intent.
• Proficiency with Python and Django. Working knowledge of TypeScript, React, and PostgreSQL.
• Proficiency in developing with AI tools (Claude Code, Cursor, OpenAI Codex, similar) and the drive to stay ahead of how AI development practices are evolving.
• Domain curiosity. You learn the business context your work supports, not just the systems. You understand why the problem matters, not just how to solve it.
• The ability to communicate clearly across engineering, product, and business, translating technical complexity without losing meaning.
• Low ego and high Emotional Quotient (EQ). You influence without authority, take feedback well, and leave your ego out of technical decisions.
• Experience working with distributed, remote teams.

HOW THIS ROLE WORKS

Product Engineering exists to collapse the distance between a problem and a working solution. You own a problem or part of a vision. You shape it with stakeholders. You build it with AI. You verify it end-to-end. You iterate until the metric moves.

You work within the Context Architecture, a shared system of documentation, design patterns, and domain knowledge that gives you the technical context to make autonomous decisions at every step.

This is not a role for engineers who need to be told how. It is a role for engineers who can take a problem, fill in the gaps with good judgment, and ship something that works.

WHO YOU WILL WORK WITH

• Derrick Franco, Principal Engineer: After teaching himself to code at 13, Derrick went on to co-found Jumpstart in addition to building out the technical divisions at InvestorsAlley and Phinaz Media Group. Nowadays Derrick spends his time reading, with his wife, and working on his podcast The Future of Work Project.

• Tony Nguyen, Engineering Manager: Tony is an engineering and platform leader with 25+ years of leadership experience at companies like Sony PlayStation Network, Intuit TurboTax, and ServiceNow. He thrives at building products, scaling teams, and leading organizations, but more so building people. He believes the best leadership and engineering comes from bringing your full identity to work. For him that's faith, family, and sports! Outside of work, you can catch him on the couch with his 3 adult children watching anime, going to Disneyland, or having game nights.
• Ron Alexessen, Engineering Manager: With experience at Hewlett-Packard, New Relic, Rackspace, and consulting agencies, Ron has built teams and shaped technical culture across different environments. He's passionate about AI-enabled development as a force multiplier and building solutions that create real business impact.

• Newton Truong, Engineering Manager: Newton joins Counterpart with 7+ years of experience in platform and data engineering. In his last company Thrive Market, he had a hand in building out new microservices and architecting data pipelines with Airflow and Spark.

COUNTERPART'S VALUES

• Conjoin Expectations - it is the cornerstone of autonomy. Ensure you are aware of what is expected of you and clearly articulate what you expect of others.
• Speak Boldly & Honestly - the only failure is not learning from mistakes. Don't cheat yourself and your colleagues of the feedback needed when expectations aren't being met.
• Be Entrepreneurial - control your own destiny. Embrace action over perfection while navigating any obstacles that stand in the way of your ultimate goal. Leverage AI ruthlessly. We measure success by outcomes, not lines of code written. Use every available AI tool to ship faster and think more strategically.
• Practice Omotenashi ("selfless hospitality") - trust will follow. Consider every interaction with internal and external partners an opportunity to develop trust by going above and beyond what is expected.
• Hold Nothing As Sacred - create routines but modify them routinely. Take the time to reflect on where the business is today, where it needs to go, and what you have to change in order to get there.
• Prioritize Wellness - some things should never be sacrificed. We create an environment that stretches everyone to grow and improve, which is fulfilling, but is only one part of a meaningful life.

We are committed to being a welcoming and inclusive workplace for everyone, and we are intentional about making sure people feel respected, supported and connected at work, regardless of who you are or where you come from.

• Free-market rigor
  Ideas rise or fall on merit and results - no committees, no politics, no cap on upside.

• Full-stack ownership
  You design, build, and run what you ship; accountability is a feature, not a bug.

• Reward for contribution
  Pay rises with impact, not years. Outstanding results earn outsized rewards. We evaluate both what you achieve and how you achieve it: living our leadership principles and using AI effectively are formally measured and rewarded.

• Relentless exploration
  Push the frontier of generative AI in live learning and - because only the paranoid survive - questioning every legacy assumption along the way.

• Is Apolitical
  You stay focused on mission-aligned outcomes, not distractions or unrelated causes.

If you’re a technically minded builder who thrives on open competition, personal responsibility, and the chance to redefine how the world learns - while continually stretching the limits of what generative AI can do - come do the most ambitious and rewarding work of your career here.
