(Senior) Full-Stack Software Engineer (m/w/d)

Salary: 60.000 - 65.000 per year

• High quality standards: while moving fast, you still care deeply about code quality and architectural soundness of the product.
• Fluency with AI-assisted / agentic development: hands-on experience driving tools like Claude Code to build real, non-trivial features, plus the discipline to review and verify their output rigorously.
• Strong 3D graphics engineering with Three.js / WebGL: scene, camera & projection math, raycasting/picking, mesh/BufferGeometry processing, render-loop performance.
• Fluency in React + TypeScript
• Backend competence in Node/TypeScript + relational SQL: NestJS or similar, PostgreSQL, transactions, concurrency.
• Mathematical & geometric literacy: enough to understand theoretical concepts, read algorithmic code and research papers.
• Product-minded and comfortable owning an under-documented, reverse-engineered problem space.
