Founding Product Engineer

Department: Engineering

Location: remote

Employment Type: FullTime

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 Youll 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 Were 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).
