Full Stack Engineer

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.

Compensation & Benefits

• Salary: $60,000 – $80,000 per year

• Hybrid work arrangement — primarily based in Munich, Germany

• Work on a core platform with real daily user impact in the AI/ML space

• Small, collaborative team with strong engineering culture and direct influence on product direction
