Founding Product Engineer

About this role

ABOUT THE ROLE This is a founding-level product engineering role on a small, high-ownership Engineering team at a fast-growing AI voice assistant startup serving SMEs across Europe. You will take end-to-end responsibility for features, from initial hypothesis through production release, working closely with customers, partners, and Sales to deliver measurable value. WHAT YOU'LL DO - Own features end-to-end, from discovery and prototyping through production deployment.

- Lead product discovery by forming and rapidly testing hypotheses with lightweight experiments. - Maintain close, recurring contact with customers and partners to surface real pain points. - Design and implement tracking to gather the metrics that drive data-informed decisions. - Build across the full stack, driving architecture choices from implementation to release. - Prioritize pragmatic solutions that balance immediate validation with long-term scalability.

- Take radical ownership of initiatives and move them forward independently. WHAT WE'RE LOOKING FOR - At least 3 years of product engineering experience delivering features end-to-end in a startup environment. - True full-stack proficiency across Node.js, TypeScript, NestJS, and React. - Experience owning software from architecture and implementation through production release. - Native-level or B2+ German proficiency, essential for supporting a German-language product.

- Fluent English for day-to-day team communication. - Deep product mindset with a focus on customer value, not just shipping code. - Comfort extracting and arguing from data, with hands-on experience setting up product metrics. - Experience integrating large language models or building AI-powered features is a strong advantage. - Experiment-driven, pragmatic approach and ability to work autonomously in a remote-first environment.

- Availability with overlap in Central European Time (CET). COMPENSATION & BENEFITS Salary range: EUR 80,000 to EUR 120,000 annually, plus equity. Visa sponsorship is not available. LOCATION Fully remote, with required overlap in CET. Primary location is Germany; an optional office in Vienna, Austria is available for those who want it.
