About the Role We are a fast-growing European AI SaaS startup building an AI-powered phone assistant platform used by thousands of small and medium-sized businesses across Europe. The product automates inbound calls—handling customer inquiries, bookings, orders, and more—with a strong emphasis on GDPR compliance and a European-first approach. As a Senior Fullstack Engineer, you will take end-to-end ownership of product features that deliver measurable value to customers. You will work in a remote-first, high-autonomy environment where shipping and customer impact matter more than meetings. Native-level German proficiency is required for this role, as the product serves German-language markets.

What You'll Do - Own features from idea and prototype through architecture, implementation, and release. - Engage continuously with customers, partners, and sales to surface real pain points. - Run product discovery by forming hypotheses and validating them with quick, lightweight experiments. - Instrument relevant metrics to enable data-driven decisions in your product area. - Build pragmatic, scalable software balancing immediate value with long-term maintainability. - Communicate asynchronously where possible and prioritize shipping over excessive meetings. - Act with radical ownership—push initiatives forward without waiting for permission. - Work remotely with CET overlap, with an occasional option to work from the Vienna office.
