Compensation is competitive and commensurate with experience. Specific details will be discussed during the interview process. You’ll be joining a small, high-calibre team at an early stage with meaningful equity participation and direct influence over technical direction.

We’re a fast-growing, Munich-based AI-powered B2B SaaS company (founded 2022, ~25 people) building privacy-first productivity tools for sales teams. Our product spans a web app, desktop client, iOS app, and backend services - all centered around real-time, low-latency data processing and seamless CRM integrations.

As a Senior Full-Stack Engineer, you’ll take technical ownership of a major platform surface, work directly with the CTO and founding engineers to shape product and infrastructure strategy, and help define how we build and ship software at scale. This is a high-impact, high-autonomy role at the heart of our engineering team. The role is hybrid and based in Munich, Germany. Visa sponsorship is not available.
