Join an early-stage AI voice assistant startup as a Founding Product Engineer to build end-to-end features on a remote-first team. You will drive architecture and full-stack development using Node.js, TypeScript, React, and NestJS while working closely with customers. The role requires 3+ years of experience, a strong product mindset, and bilingual proficiency in German and English.
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.
