About this role

ABOUT THE ROLE We are a bootstrapped AI platform studio based in Munich, Germany, building an all-in-one AI platform that empowers teams across the SME sector to integrate AI into their everyday workflows. Our platform already serves a large and rapidly growing user base across hundreds of companies, and we're scaling fast. You'll join a small, product-focused engineering team where your architectural decisions will have real, immediate impact.

We're looking for a Senior Full Stack Engineer who thrives on complex infrastructure challenges, cares deeply about user experience, and wants to help shape engineering culture alongside a talented team. WHAT YOU'LL DO - Own the most complex architectural problems on the platform — including multi-terabyte data synchronization and secure sandbox infrastructure. - Architect, build, and ship high-quality full-stack features using React and TypeScript with a focus on long-term scalability and UX.

- Design and implement systems to synchronize and index large volumes 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 drive alignment on architectural decisions with the wider development team. - Debug production incidents, identify root causes, and implement durable fixes to maintain platform stability. - Mentor junior engineers and elevate the codebase through thorough, constructive code reviews. - Continuously improve development processes, code quality standards, and overall team performance.

WHAT WE'RE LOOKING FOR Required: - 7+ years of professional software engineering experience with React, TypeScript, PostgreSQL, and the surrounding ecosystem (Docker, CI/CD). - Proven experience designing, scaling, and maintaining complex software architectures for high-growth products. - Hands-on experience with tRPC (or an equivalent type-safe API communication framework), Kubernetes, and Docker. - Experience with PostgreSQL relational data modeling and query performance optimization.

- Experience designing and implementing secure, multi-tenant sandbox environments. - Experience operating at scale: synchronizing large datasets, handling high volumes of LLM/API calls, and building secure multi-tenant systems. - Strong product ownership mindset with genuine attention to user experience and long-term product success. - A passion for mentoring engineers and actively shaping engineering standards and processes.

- Willingness to work on-site in Munich, Germany (hybrid arrangement). Nice to Have: - Prior experience working in AI platforms, LLM infrastructure, or similar AI/ML-adjacent products. - Background at an IT consulting, enterprise software, or B2B SaaS company. - Experience contributing to a fast-paced, small team environment where you've worn multiple hats. COMPENSATION & BENEFITS - Salary: €70,000 – €90,000 per year, depending on experience.

- Hybrid work arrangement based in Munich, Germany. - A high-impact role in a close-knit, product-focused team at an early-stage company. Please note: visa sponsorship is not available for this role. Candidates must already be authorised to work in Germany. LOCATION This is a hybrid role based in Munich, Germany. Regular on-site presence is expected. Visa sponsorship is not available.
