About this role
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 RoleAs 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 ExpectBuild 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 ProfileStrong 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
Strong debugging skills across browser runtime, network events, and backend responses
Ability to own features end-to-end and collaborate closely with product and design
Nice To HaveExperience 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: build the world's first truly functional hardware design agent. 3D modeling tools were the last major leap in this space, but the way we design parts today has hit its limit. It's time for something radically better, and we're at the start of it.
As one of our first hires, you won't just execute the vision, you'll help shape it, with a competitive salary and stock options to match.
