Senior Full-Stack Engineer

Kombo (YC S22) is building a unified API that saves engineering teams, on average, hundreds of hours by needing to integrate only one API instead of 50+. We're looking for a product-minded full-stack engineer to own one of our 3 product verticals and to build new features for our growing customer base.

Since going through Y Combinator in 2022, we've grown from zero revenue to $4M+ ARR and hundreds of customers in 24 months, scaled to process data for the equivalent of 10% of Germany's workforce, raised $8M+ of funding, and grown to a team of 30+ Kombies.

As a Full-Stack Engineer, you'll take ownership over a large portion of one of our product verticals and own projects end-to-end. You'll research competitors, write product specs, make wireframes, and build features that customers actively request and start using the same day.

Our tech stack includes Node.js, React, TypeScript, PostgreSQL, GCP, Docker, and Prisma. We maintain a focused tech stack with a monorepo architecture that lets us deploy our entire codebase at once. Our development environment sets up with a single command, tests run in seconds, and we deploy 20+ times per day.

We've built Kombo with the quality, breadth, and depth that customers would expect from teams many times our size through three core principles:

• Simplicity Above All: We like boring technologies and invest in having modular, simple abstractions
• Focus on Developer Experience: We've built a core framework that enforces best practices through strict typing and linting
• High Ownership & Agency: Engineers own features end-to-end and make both technical and product decisions

Our culture is built around high ambition and performance while providing a fun and supportive environment. We work primarily from our Berlin office (4+ days/week) and have a strong writing culture, using long-form documents to make important decisions.

The ideal candidate:

• Thrives with autonomy and owns projects end-to-end
• Has strong engineering fundamentals and codes efficiently
• Prefers building and shipping over meetings
• Is comfortable working primarily from our Berlin office

Join us if you want to be part of a fast-growing environment (~2-3x per year) that feels like a different company every few months, working on features that directly impact thousands of developers.
