Careers



Full Stack Engineer

 
The Role
You’ll be a backend-focused full-stack engineer. Primarily (75%) building and maintaining NestJS microservices—writing APIs, optimizing databases, handling real-time events. But you’ll also (25%) work on React interfaces to ensure smooth integration between backend and frontend. You’ll own the full lifecycle of features: API design, implementation, frontend integration, and deployment. Starting as one person, you’ll be responsible for keeping multiple services healthy and delivering features end-to-end.
