Requirements
- Have 7+ years of professional experience in building production, distributed, event-driven Node.js applications and RESTful APIs, with strong technical expertise across backend architectures.
- Are proficient in modern JavaScript/TypeScript and have advanced experience with Nest.js.
- Have solid knowledge of databases (PostgreSQL, MongoDB, Redis), cloud platforms (AWS, GCP, Azure), and modern backend architectures such as microservices, serverless, and event-driven systems.
- Have already experimented with Claude Code or other AI pair-programming tools - and can’t imagine going back to coding without them.
- Are experienced with Docker, CI/CD pipelines, and monitoring/logging systems.
- Communicate confidently in English; Polish is a bonus, as many teammates are based in Poland.
- Thrive in fast-paced, ambiguous environments where switching contexts and wearing multiple hats is part of the fun.
- Believe in craftsmanship - automated testing, clean architecture, security best practices, and performance optimization come naturally to you.
- Understand scalability challenges and know how to design systems that grow smoothly from MVP to millions of users.
Responsibilities
- Code smarter and ship faster with Claude Code, Cursor/Windsurf, and any ingenious tools you bring to the team.
- Design and build robust APIs, microservices, and server architectures in Node.js.
- Develop our AI-native platform for developers, with your feedback and features feeding directly into the product roadmap.
- Collaborate remotely with frontend developers, designers, PMs, and engineers across Poland and Saudi Arabia on multiple ventures simultaneously.
- Own the backend lifecycle: architect, implement, optimize, monitor, and scale.
- Champion best practices in API design, database optimization, security, and DevOps automation.
