AI Product Engineer (Backend, Node.js)
Smeetz is an AI-powered unified commerce platform for the European leisure and entertainment industry. Theme parks, family entertainment centres, museums, zoos, and theatres run their ticketing, seating, F&B, and payments on us.
This role owns the backend of our two AI surfaces: the Smeetz MCP server and the AI chatbot. Both are backend services at heart, made of APIs, integrations, and agent logic sitting on top of our commerce platform. Expect to spend about 70% of your time on backend engineering (building, scaling, and running these services in production) and about 30% on the product side (understanding how venues use them, shaping what gets built next, and measuring whether it worked).
You report to the VP of Engineering and have no direct reports.
