We're building the world's fastest way to design real, functional 3D parts. Kyrall's AI-powered design agent turns ideas into ready-to-manufacture 3D models in seconds.
Backed by top European VCs, we're a young, well-funded startup based in Munich and we're just getting started.
The Role
- As a Full-Stack Engineer, you'll own product features end-to-end across our TypeScript React frontend and Python FastAPI backend with WebSocket services, SQLAlchemy, and PostgreSQL. You'll ship reliable real-time experiences for 3D model generation, editing, history, and project workflows.
What to expect
- Build frontend features in React + TypeScript using shared components, Tailwind, and React Query
- Implement backend FastAPI routes and WebSocket handlers for render flows
- Design stable real-time contracts (payloads, statuses, retries, and error semantics)
- Model and optimize data flows using SQLAlchemy + PostgreSQL for schemas lifecycle
- Debug and fix cross-stack issues such as hydration errors, race conditions, and stale state sync
Your profile
- Strong full-stack engineering experience with TypeScript and modern web stacks
- Production experience with React, hooks, and state management patterns
- Hands-on experience with Python FastAPI, WebSocket architecture, and long-running workflows
- Strong SQL and ORM experience, ideally SQLAlchemy with PostgreSQL
- Ability to own features end-to-end and collaborate closely with product and design
Nice to have
- Experience with 3D web/model viewer workflows (GLB, thumbnails, geometry tooling)
- Experience with observability for async systems (structured logs, tracing, metrics)
- Familiarity with cloud infrastructure and CI/CD practices
Why Kyrall?
We're reinventing how machines are designed and built; from the ground up. Our mission: to build the world's first truly functional hardware design agent. The last major leap in this space was the shift to 3D modeling tools, but the way we currently design 3D models has reached its limit. Now is the time for something radically best… (some text) etc ...
