Founding Product Engineer

myDataValue | Founding Product Engineer | London (Canary Wharf) | HYBRID, 2 days/week in office | up to £90k + up to 1% equity | https://www.mydatavalue.com/founding-product-engineer/ We build AI agents that run revenue for short-term rental and hotel operators on Booking.com and Airbnb: live prices, promotions and visibility on real portfolios, plus an MCP connector so customers work their accounts from Claude and ChatGPT. Our engineers no longer type most of the code. Claude Code and Codex do. The hard part is knowing what to build, how it should fit together, and whether what the agent wrote is actually right. You will talk to customers, own the architecture, write the briefs, and catch what the agent missed. We do not care which language you know. We care that you can do architecture (single source of truth, clear boundaries, the right layer for a fix) and that you already ship this way. Big bonus if you have worked on hotels, short-term rentals or dynamic pricing. Small team, paying customers, hard problems (private OTA APIs, PMS integrations, pricing decisions that move real money). Three interview stages, no take-home.
