Job Description:

Full-Stack Engineer - AI-Native Agentic Travel Platform We are building a deeply personal, AI-native travel companion designed to become the trusted travel agent for life. Travel is one of the most meaningful parts of people's lives - yet today's tools remain fragmented, transactional, and disconnected from user intent. We are creating a system that learns each traveler over time, applies judgment, and handles complex multi-step travel planning and booking through an intelligent agent. The product is AI-native from the ground up, where agent behavior, trust, and long-term memory are core system primitives. We are seeking a Full-Stack Engineer to build and ship core product experiences end-to-end across web and mobile surfaces, powering how users plan, book, and manage travel through AI systems. What You'll Do Build Agentic User Experiences Design and implement conversational travel planning interfaces Build AI-driven agents that reduce cognitive load and guide users through complex travel decisions Ship end-to-end product features across frontend, backend, and AI systems Build Long-Term User Intelligence Develop systems that construct and maintain durable user travel profiles Design data models that support long-term memory and personalization Build systems that evolve user understanding from real behavioral signals over time Design and Implement Booking Systems Build multi-step booking agents with strong guardrails and controllable execution flows Implement transactional systems for search, booking, and observability
