## About the role

##### About the Role

This is a Senior Fullstack Engineer role at a fast-growing European AI voice assistant company serving small and medium-sized businesses. You will take end-to-end ownership of product features, from early discovery and prototyping through to architecture, implementation, and release, in a remote-first environment with a strong product and customer focus.

##### What You'll Do

- Own features across the full product lifecycle: idea, prototype, architecture, implementation, and release.

- Engage regularly with customers, partners, and Sales to surface real pain points and define value.

- Run product discovery by forming hypotheses and validating them quickly through lightweight experiments.

- Instrument your areas of ownership and gather metrics to support data-driven decisions.

- Build pragmatic, scalable software that balances immediate value with long-term maintainability.

- Communicate asynchronously and prioritize shipping over excessive meetings.

- Act with radical ownership and drive initiatives forward independently.

##### What We're Looking For

- 5+ years of experience in fullstack engineering with end-to-end delivery responsibility for customer-facing web applications.

- Strong hands-on experience with Node.js, TypeScript, NestJS, and React; substantial frontend and backend coverage is required.

- Experience with product discovery: forming hypotheses and validating them quickly through experiments.

- Comfortable identifying, collecting, and using metrics to inform product decisions.

- Skilled at collaborating directly with customers and partners to extract actionable insights.

- Native-level German proficiency is required; fluent English is also expected for team communication.

- Experience integrating LLMs (such as OpenAI) into production software is a strong plus.

- Familiarity with GDPR and EU AI Act considerations for AI-powered services is a plus.

- Experience working in a high-growth startup environment is a plus.

- Strong CS fundamentals and sound judgment around effort, quality, and speed trade-offs.

##### Compensation & Benefits

Salary range: **80,000 to 120,000 EUR annually**. Visa sponsorship is not available.

##### Location

Fully remote, with a preference for candidates based in Germany or Austria and availability during Central European Time hours. Occasional in-person collaboration in Vienna is possible.
