About the Role
We're a fast-growing, Vienna-headquartered AI communication startup building an AI phone assistant platform for SMEs across Europe — and we're looking for a Founding Product Engineer to join our engineering team. This is a high-ownership, end-to-end role at the intersection of product thinking and full-stack engineering. You'll help shape the product from hypothesis to production, working closely with customers, partners, and sales to deliver features that create real, measurable business value.
We're a remote-first team with an optional office in Vienna. You'll need meaningful overlap with Central European Time (CET). Our product is German-language-first, so native-level German proficiency is essential.
What You'll Do
-
Own features end-to-end — from hypothesis and prototype through architecture, implementation, and production release.
-
Lead product discovery by designing and running rapid experiments to validate ideas before committing to large-scale builds.
-
Maintain close, recurring contact with customers, partners, and the sales team to surface real pain points and translate them into product decisions.
-
Design and implement tracking and analytics to enable data-driven iteration.
-
Drive architecture choices across the full stack and take responsibility through to release.
-
Prioritize pragmatic, scalable solutions that balance speed of validation with long-term quality.
-
Take radical ownership of your initiatives — move things forward without waiting for sign-offs.
What We're Looking For
Must-haves (dealbreakers):
-
3+ years of experience in Product Engineering delivering end-to-end software features.
-
Strong full-stack proficiency: Node.js, TypeScript, NestJS, and React.
-
Native-level German fluency (Deutsch auf Muttersprache-Niveau) — essential for our German-language product and customer interactions.
Required:
-
Experience integrating software with external systems (CRMs, calendar tools, databases, APIs).
-
Ability to gather customer feedback and convert pain points into prioritized product decisions.
-
Comfort identifying, tracking, and analyzing product metrics to drive data-informed choices.
-
Proven experience owning the full development lifecycle from architecture to production.
Nice to have:
-
Experience working with AI/LLM integrations (e.g., OpenAI or similar) — this is a strong advantage.
-
Familiarity with GDPR compliance and EU AI Act considerations in product development.
-
Background working in remote-first, asynchronous environments at early-stage or high-growth startups.
Compensation & Benefits
-
Salary: €80,000 – €120,000 annually, depending on experience.
-
Equity: Meaningful equity stake as part of a high-growth founding team environment.
-
Remote-first flexibility with optional office access in Vienna.
Please note: visa sponsorship is not available for this role.
Location
Fully remote, with a preference for candidates based in Germany or able to work with significant CET overlap. An optional co-working office is available in Vienna, Austria.
