Werkstudent Fullstack Software Developer

We are building a next-generation B2B marketplace from Hamburg, — currently in stealth mode.

Our approach is defined by speed, ownership, and engineering excellence. We are creating a system where technology, logistics, and pricing intelligence converge — and we are doing so with a small, highly capable team.

We are looking for a highly capable Fullstack Software Engineer (primarily working student) who is eager to take ownership, build end-to-end systems, and contribute directly to the core of the product.

This is not a role for incremental work — it is a role for builders.

Tasks

You will take ownership of critical parts of the platform and work across the full stack:

• Design and implement end-to-end features (frontend → backend → database)
• Architect and build scalable APIs and services
• Develop high-performance, clean user interfaces using modern React patterns
• Drive performance optimization and architectural decisions
• Collaborate closely with founders on product and technical direction
• Your work will have direct and measurable impact on the evolution of the company.

We operate a modern, TypeScript-first architecture:

• Next.js
• Hono
• Drizzle ORM
• PostgreSQL
• Bun runtime
• TypeScript across the entire stack
• AI-Native Engineering

We actively integrate AI into our development workflow:

Requirements

We value ability, depth, and mindset over years of experience.

You should bring:

• Strong full-stack engineering capability with the ability to build systems end-to-end
• Deep proficiency in TypeScript and modern web development practices
• Experience with scalable, production-grade architectures
• High standards for code quality, structure, and maintainability
• A strong sense of ownership and accountability for outcomes
• Ability to work at high velocity without compromising precision
• Well-developed product intuition and the ability to make pragmatic decisions
