Maintain regular contact with customers, partners, and Sales to surface and prioritise real pain points.
Design and implement tracking and metrics to support data-driven iteration.
Build across the full stack, driving architecture decisions and implementation through to release.
Balance pragmatic, fast-moving solutions with long-term scalability needs.
Take radical ownership of initiatives and drive them forward independently.
What We're Looking For
At least 3 years of product engineering experience delivering features end-to-end.
True full-stack proficiency across Node.js, TypeScript, NestJS, and React.
Hands-on experience in a startup or high-growth environment.
Native or near-native German proficiency (B2 or above), essential for supporting a German-language product.
Fluent English for team and cross-functional communication.
Strong product mindset with ownership that extends well beyond writing code.
Comfort extracting and owning relevant metrics to argue for and iterate on decisions.
Experience integrating large language models or building AI-powered features is a strong advantage.
Availability to work with CET time-zone overlap.
Compensation & Benefits
Salary range: 80,000 to 120,000 EUR annually, plus equity. Visa sponsorship is not available.
Location
Fully remote, with a preference for CET time-zone overlap. Candidates based in Germany or Austria are a strong fit. An optional office in Vienna is available.
