Salary: 70,000 to 100,000
Company: VC back Startup
About the Role:
This startup is building a cutting-edge platform to transform how engineers design physical products. Instead of creating one solution at a time, this system enables users to generate, visualise, and explore thousands of design alternatives. Faster and more intelligently than ever before.
Looking for someone who enjoys writing clean, wellstructured code and has a genuine interest in engineering not just software, but how things are built in the real world. Backed by one of Europe's leading VCs and with a 4-year runway. This company has assembled one of the strongest technical founding teams I've seen. Bringing together brilliant minds from Cambridge, MIT, and Google across Software Engineering, Data Science, Theoretical Physics, and Computational Geometry.

- Backend: Python, FastAPI, Pydantic, PostgreSQL, Docker
- Frontend: React, TypeScript, Vite
- Infrastructure: GitHub Actions, GCP, Kubernetes (optional)
- Paradigms: Functional programming, async APIs, event-driven architecture
Responsibilities
- Build and maintain backend services using FastAPI and Python for geometry, simulation, and data workflows
- Develop responsive, performant frontends using React and TypeScript
- Work closely with domain experts (engineers, designers) to translate complex physical problems into usable software features
- Follow functional programming practices to write testable, composable code
- Own features from idea to implementation to deployment
- Contribute to architectural decisions in a fast-moving, early-stage product
Requirements
- Bachelor's degree in Computer Science
- 2+ years of experience building web applications in a production environment
- Strong experience with Python and API frameworks (FastAPI, Flask, etc.)
