ABOUT THE ROLE
Join a fast-growing, self-funded AI platform startup based in Munich that is building the infrastructure enabling thousands of users to interact with AI every day. As a Full Stack Engineer, you will be a core contributor to the platform — owning features end-to-end, architecting scalable backend systems, and helping shape how businesses connect their data to AI workflows. This is a hybrid role based in Munich, Germany. Visa sponsorship is not available.
WHAT YOU'LL DO
- Build and ship high-quality full-stack features using TypeScript and React, with a strong focus on seamless user experience.
- Design and implement robust backend systems capable of handling massive data scale and millions of API requests.
- Take full end-to-end ownership of features — from concept and architecture through deployment and ongoing operation.
- Debug production incidents, identify root causes, and implement durable fixes.
- Synchronize and index terabytes of client data while managing fine-grained permissions.
- Operate and optimize systems that process millions of LLM calls per month with high reliability.
- Architect and scale environments that spawn thousands of secure code sandboxes per day.
- Build foundational infrastructure to enable rapid onboarding of custom integrations.
- Mentor junior engineers and raise the bar through thorough, constructive code reviews.
- Collaborate closely with AI integration and product teams to shape the user experience on the platform.
WHAT WE'RE LOOKING FOR
Must-have:
- 3+ years of professional software engineering experience delivering production full-stack applications using React, TypeScript, and PostgreSQL.
- Proven experience with Kubernetes-based deployment and container orchestration.
- Hands-on experience with Docker and CI/CD pipelines in production environments.
- Strong track record building and scaling backend services for high data volumes and millions of API requests, with a focus on reliability and security.
- Ability to own features completely — from design decisions through debugging live production issues.
Nice to have:
- Experience with Python, tRPC, or similar backend technologies.
- Familiarity with GenAI platforms or LLM integrations (e.g. OpenAI, Anthropic, or similar).
- Experience mentoring junior engineers or leading technical code reviews.
- Comfort working in a fast-paced, high-growth product environment.
