Product Engineer (Full-Stack / Agentic AI)

A well-funded European PropTech company building an AI-native operating system for short-term and holiday rental management 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 central, full-ownership role: you’ll modernise legacy systems, redesign data structures, and turn messy operational workflows into reliable, autonomous software. What You’ll Do Own features end-to-end - from requirement gathering through to production-ready shipping. Design and build agentic AI workflows covering guest communication (chat and voice), operational decisions, and property tasks. Modernise legacy systems and redesign data structures to meet evolving product requirements. Shadow real operational workflows to surface inefficiencies, hidden steps, and workarounds. Translate complex, messy processes into clean, scalable software. Scope, ship, and iterate - driving solutions independently rather than working from a ticket queue. Collaborate closely with internal teams to keep product and engineering aligned. Operate with high agency and ownership, delivering results rapidly and safely.

Required: Demonstrable engineering experience you can show during the hiring process. Strong TypeScript skills - this is a firm requirement. Proven ability to own features end-to-end: from gathering requirements to shipping production software. Track record of shipping quickly with sound judgement about what can safely break. Familiarity with React, Express, PostgreSQL, MongoDB, and AWS; comfortable using Linear and Notion for tracking and documentation. Comfort working in an agentic engineering style - e.g. running multiple agents, parallel terminals, and AI coding assistants. Strong product taste: attention to user experience down to messaging and interaction wording. Ability to self-manage: plan work, communicate progress, and flag blockers proactively. Fluent English and strong written/verbal communication skills. Willingness to relocate to Germany and work from the Berlin office periodically. Nice to Have: Founder mentality or prior startup founding experience. Background in PropTech, hospitality tech, or operational automation.
