Senior Full-Stack Engineer, CYPEX (full-time, Remote in Europe)

We are hiring a senior engineer to own features across the full stack: the database layer, the API, and the user interface.

Tasks

• Own features end to end, from the data model through the API to the user interface.

• Design and review the database side of features: schema changes, migrations, queries, and access control.

• Build backend services in TypeScript on Node.js and Express.
• Build frontend features with React, Vite, MUI/Emotion, Redux and React Query.

• Set technical direction in your area and document the reasoning, so the next engineer can follow the decision without asking you.

• Review other people’s code with the same care you expect on your own.
• Support mid-level engineers on the team.

• At least five years building production web applications in TypeScript, covering both
• frontend and backend.

• Solid PostgreSQL experience. You can read a query plan, write a migration you would be willing to run against a customer’s production database, and reason about permissions.

• You test what you build and can explain how you know a change is correct.
• You debug across layers instead of stopping at the first plausible cause.
• You raise risks early, including the ones you created yourself.
• Fluent English, written and spoken.
