ABOUT THE ROLE Join a fast-growing European AI voice tech company building an AI-powered phone assistant for small and medium-sized businesses. As a Senior Fullstack Engineer, you'll take end-to-end ownership of product features — from idea and prototype through architecture, implementation, and release — on a remote-first team with real customer impact. WHAT YOU'LL DO - Own features across the full stack, from discovery and architecture to shipping and measuring outcomes. - Engage directly with customers, partners, and Sales to surface real pain points and inform what gets built. - Form hypotheses and validate them quickly through lightweight experiments before committing to large-scale solutions. - Instrument features and gather metrics to enable data-driven product decisions. - Build pragmatic, scalable software balancing immediate customer value with long-term maintainability. - Communicate and collaborate asynchronously, prioritizing shipping over excessive meetings. - Act with radical ownership — push initiatives forward without waiting for permission. WHAT WE'RE LOOKING FOR - 5+ years of experience in fullstack engineering with end-to-end delivery responsibility for customer-facing applications. - Strong hands-on experience with Node.js, TypeScript, NestJS, and React. - Experience integrating LLMs (e.g., OpenAI) into production software applications — a significant plus. - Product mindset: you measure success by customer value, not lines of code. - Skilled at extracting actionable insights from direct conversations with users, partners, and sales teams. - Comfortable owning analytics, tracking, and the data layer needed to support product decisions. - Experience deploying AI-enabled services on cloud infrastructure in Europe (e.g., Microsoft Azure) is a bonus. - Familiarity with GDPR and EU AI Act considerations for AI-powered services is a plus. - Experience working in a high-growth startup environment. - Strong CS fundamentals and sound judgment when trading off effort, quality, and speed. - Native-level German proficiency is required — the product serves a German-language market. COMPENSATION & BENEFITS Salary range: €80,000 – €120,000 annually. Visa sponsorship is not available. LOCATION Fully remote, with a preference for candidates based in Germany or Austria (CET timezone overlap expected). Optional access to a Vienna office.
