Jobs in Germany
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.
What We're Looking For
Required
5+ years of professional experience with React and TypeScript (dealbreaker).
7+ years of overall professional software engineering experience.
2+ years of backend development experience with Node.js/Express or equivalent.
Proficiency with containerisation and orchestration using Kubernetes and Docker.
Hands-on experience with PostgreSQL, tRPC, and modern CI/CD pipelines.
Proven track record designing, scaling, and maintaining complex software architectures for high-growth products.
Experience operating at scale: large dataset synchronisation, high-volume API/LLM calls, secure multi-tenant systems.
Experience mentoring junior developers or leading a small development team.
Ability to own a product roadmap, drive technical decisions aligned with product goals, and collaborate effectively with product managers and designers.
Excellent written and verbal communication skills in a cross-functional environment.
Authorised to work in Germany without employer visa sponsorship.
Nice to Have
Familiarity with AI platforms or AI workflow tooling.
Experience in the B2B SaaS or AI/ML industry.
Tech Stack
