Our systems tackle the hardest shop-floor problems: allocating scarce resources, routing around breakdowns, and handling last‑minute rush orders with machine learning, optimization, and intelligent agents. We operate at the core of the value chain, where machines, people, and materials turn into real products, then expand outward to shape what manufacturers build, where they invest, and how they scale. We're building Software 3.0 systems that learn, reason, and continuously improve from the chaos of production. If you want to ship hard tech that actually changes how the world builds things, this is where you do it. What You'll Do As a Fullstack Engineer Working Student, you build and ship features across the stack 20h/week alongside your studies. You work closely with the founders on real product surfaces, not side projects. This will include things like: - Improve navigation and performance using TanStack Router. - Optimize tRPC and TanStack Query (caching, optimistic updates). - Build dynamic, nested forms with TanStack Form. - Work on performant Gantt charts with drag-and-drop using DOM/Canvas APIs. - Extend TanStack Table with drag-and-drop and advanced filtering. - Develop a React Flow–based operations configuration editor. - Contribute to access control flows with WorkOS. - Help refine database schema and ERP integrations. What We're Looking For - Enrolled student (CS or similar) available 20h/week. - Solid TypeScript + React experience from projects or hackathons. - Interested in owning features end-to-end across frontend and backend. - Excited about performance, clean abstractions, and learning fast in a small team. Your Profile - You love to build complex products from 0→1 - You thrive in small teams and take full ownership from concept to deployment - You're fluent in English, with strong communication skills - Impressive side projects are as valid as work experience, all that matters is curiosity and the ability to go deep. How to Apply Send us a link to a project that represents your best work (or your GitHub), and include three sentences explaining why you're the right fit for this role.
