About the Role
We're a product-focused AI platform and product studio based in Munich, helping hundreds of SMEs integrate AI into their core workflows. Our platform already serves a large and fast-growing user base, and we're scaling toward the next order of magnitude. We're looking for a Senior Full Stack Engineer to join our engineering team and own some of the hardest architectural challenges we face — from multi-terabyte data synchronisation to secure, high-throughput sandbox infrastructure.
This is a hybrid role based in Munich, Germany. No visa sponsorship is available — candidates must be authorised to work in Germany without employer sponsorship.
What You'll Do
-
Own the most complex architectural problems across the platform, including multi-terabyte data synchronisation and secure sandbox infrastructure.
-
Architect, build, and ship high-quality full-stack features using React and TypeScript, with a strong focus on long-term scalability and UX.
-
Design and implement systems to synchronise and index terabytes of client data while enforcing fine-grained permissions.
-
Build infrastructure to process millions of LLM calls per month with high reliability and security.
-
Implement scalable, secure code sandbox solutions capable of spawning thousands of sandboxes per day.
-
Create base infrastructure and tooling for fast custom integrations, enabling new systems to be connected in hours.
-
Collaborate on technical roadmaps and align on architectural decisions with the broader engineering team.
-
Debug production incidents, identify root causes, and implement durable fixes to keep the platform stable.
-
Mentor junior engineers and raise the bar across the codebase through constructive, thorough code reviews.
-
Continuously improve development processes, code quality standards, and overall team performance.
