Growth-Driven Full-Stack Engineer, Self-Serve Platform
Summary

Firsty.app in Amsterdam is seeking a Full-Stack Software Engineer (Growth) who will own the end-to-end product—from front end to back end to growth metrics—without relying on a predefined spec. You ship, and you ship fast, with a bias for action and ownership.
You will build the developer portal, SDKs, and API experience that makes partners go live with minimal friction, measure activation and retention, and iterate based on real data in a small, autonomous team.
