Full-Stack Developer (EU) - AWS

We're hiring the first dedicated engineer to join B2B Saas startup. You'll work directly with the team lead — a hands-on engineer with deep enterprise and high-scale experience — on a product that's already live, focusing on improving it and shipping new features rather than building from scratch.

This is a high-ownership role on a small, autonomous team. As the product grows, so will the team — early hires will help shape it.

What You'll Do

• Build and ship features across the full stack: TypeScript on the backend, TypeScript/React on the frontend
• Work with a fully serverless AWS architecture, managed entirely through infrastructure as code (no console click-ops)
• Design for scale: reason about high volumes, retries, failure modes, and edge cases in distributed, queue-based systems
• Use AI coding tools effectively as part of your daily workflow — we care less about typing code by hand and more about how you direct, review, and validate AI-generated work
• Communicate proactively and move fast in a chill but high-output team

What We're Looking For

Must have:

• Strong AWS experience (DynamoDB, Lambda, SQS/SNS, and CloudFront)
• Backend development in TypeScript (Node.js)
• Frontend development in TypeScript / React
• Solid understanding of serverless architecture and event-driven systems — e.g., you can explain how you'd handle retries, poison messages, and transient errors in a queue-based pipeline
• Mid-to-senior level of autonomy: you don't need hand-holding, but you're open to mentorship on high-scale patterns
• Experience at a startup or a fast-moving product company (think Revolut/Spotify pace, not slow maintenance work)
• Based within roughly ±4 hours of Central European Time, with good availability and responsive communication during overlapping hours

Nice to have:

• Strong frontend/UI sensibility
• Experience scaling systems for large volumes
• Experience with high-volume messaging, cloud infrastructure, or similar systems
