## About the role

Join our product engineering team in the US to build features that directly impact how customers experience and adopt our platform. This role bridges technical execution and product thinking - you'll ship user-facing features while making architectural decisions across the entire stack. You'll work end-to-end: designing interfaces, building APIs, optimizing performance, and deploying to production. We move fast, iterate with users, and expect engineers to own problems from concept to launch.

## What they're looking for

- - Strong full-stack development experience (frontend + backend)
- - Proficient in React and modern JavaScript/TypeScript
- - Python skills with FastAPI or similar frameworks
- - Experience with PostgreSQL, Redis, and async patterns
- - Comfortable with AWS/Azure/GCP, deployment pipelines, and infrastructure basics
- - Product mindset - you care about user experience and customers, not just code
