Founding AI Engineer

Pearl is building the future of travel, where you can be treated like a regular wherever you go and venues can give personalized service to anyone who walks through the door. We are the platform reinventing how the world's most discerning travelers discover, share and book places, and how venues tailor service to them. This is not a mass market product. We are building the Ferrari of travel. We are pre-seed, venture backed, and have more than $2M in credit grants from Google, Anthropic, OpenAI, AWS, and Microsoft. Pearl learns each member's taste and uses it to curate exceptional places. An AI agent turns a prompt into a considered itinerary, plans the details, and handles the bookings. Members connect with people of similar taste, and that community is itself another source of discovery. Every choice deepens a taste profile that travels with them. Venues get the context to anticipate preferences and cater service. The real-world experience is more personal, and more carefully curated. Your job is to own the systems that make Pearl feel personal: the taste models that curate places, ranking and retrieval, the taste profile that travels with each member, and the models behind the planning and booking agent. There is no platform team, no PM writing tickets, and no one else to own this in production. The job You ship taste, ranking, retrieval, search and maps, and member/venue embeddings end to end. You keep the member's taste profile current as they travel. You put the planning and booking agent's models in production and keep them there. You help set the bar for how we build this, and you hire the next people on it. What you will do - Own the taste and curation models members actually use - Improve search, maps, ranking, and retrieval so people find the right place - Embed member, venue, and social data so the system actually understands taste - Power the AI agent that plans itineraries and completes bookings - Put models in production. Evals, latency, cost, and uptime are yours. If it is wrong, you see it - Sit with the product. Talk to members and venues. Cut scope.
