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.

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.
