Product Engineer (Full-Stack / Agentic AI)

ABOUT THE ROLE A fast-growing, Series A PropTech company building an AI-native operating system for short-term and holiday rental management across Europe is looking for a Product Engineer to join a lean, high-impact team. You'll design and ship agentic AI systems that observe, decide, and act on real-world property operations — with humans in the loop. This is a full-stack, ownership-heavy role at the intersection of product thinking and engineering execution. You won't be handling tickets — you'll be driving outcomes end-to-end, modernizing legacy systems, and turning messy operational workflows into reliable, autonomous software. WHAT YOU'LL DO - Own features end-to-end, learning the business deeply enough to drive solutions independently. - Design and build agentic AI workflows for guest communication (chat and voice), operational decisions, and property management tasks. - Modernize legacy systems and redesign data structures to meet evolving product requirements. - Shadow real operational workflows to uncover inefficiencies, workarounds, and hidden steps. - Translate messy processes into clean, production-ready software. - Scope, ship, and iterate on problems rather than just executing predefined specs. - Collaborate with internal teams to align product and engineering direction. - Operate with high agency and ownership to deliver results rapidly and safely. WHAT WE'RE LOOKING FOR Required: - Demonstrable engineering experience you can walk through during the hiring process. - Strong proficiency in TypeScript and React for full-stack development. - Familiarity with Express, PostgreSQL, MongoDB, and AWS. - Comfortable working in an agentic engineering style — running multiple agents, parallel terminals, and AI coding tools (e.g. Claude Code, Codex). - Strong product taste: attention to user experience down to interaction wording and messaging. - Ability to self-manage: plan work, communicate progress, and proactively flag blockers. - Track record of shipping quickly with sound judgment about acceptable risk. - Fluent spoken and written English. - Experience with Linear and Notion (or equivalent) for work tracking and documentation. - Willingness to relocate to Berlin, Germany and work from the office regularly. Nice to Have: - Experience building agentic AI or AI agent systems. - Prior startup experience or a founder mentality. - Background in hospitality, PropTech, or short-term rental domains. - Strong product-minded approach with a track record of influencing product direction. Please note: No visa sponsorship is available. Candidates must be eligible to work in Germany without sponsorship. COMPENSATION & BENEFITS - Salary range: $90,000 – $110,000 USD annually - Lean, accountable team focused on outcomes over process - High ownership and direct impact on a core product - Work at the cutting edge of applied AI in a real-world operational domain LOCATION This role is on-site in Berlin, Germany. Candidates should be based in or willing to relocate to Berlin. The team also has presence in other German cities and Vienna, Austria.
