We're a fast-growing, remote-first AI startup building a German-language AI phone assistant used by thousands of small and medium-sized businesses across Europe. With a team of ~50 and serious seed-stage backing, we're scaling quickly and looking for a Senior Fullstack Engineer to take end-to-end ownership of product features that create measurable value for our customers.
You'll work at the intersection of engineering and product — forming hypotheses, running experiments, shipping fast, and iterating based on real customer insights. This role is a great fit if you care deeply about outcomes over output and love talking to customers as much as you love writing clean code.
Note: Native-level German proficiency is a hard requirement for this role. Visa sponsorship is not available.
