If you're ready to challenge the status quo and build the future of travel tech, your next journey starts here. We’re hiring 2 x Senior Full Stack Engineer to own the end-to-end development of our next-gen AI products. You'll bridge the gap between complex AI capabilities and beautiful user experiences, developing the customer-facing features, high-performance APIs, and reliable backend services that make intelligent, autonomous workflows reality. What You’ll Do Build Meaningful Experiences: Partner closely with a cross-functional team of designers, product managers, and ML engineers to shape and deliver thoughtful, high-quality AI-powered user experiences. Bridge Frontend & Backend: Co-create and refine full-stack features, utilizing React/Next.js for intuitive frontends and Python or Node.js to power robust, reliable backend services. Bring AI to Life: Integrate LLM APIs and innovative agentic frameworks into fluid product features—crafting interactive streaming UIs, clear tool-call results, and helpful agent status displays.

Champion Quality Together: Write thoughtful unit, integration, and end-to-end tests to ensure product excellence, and engage in constructive, supportive code reviews that help the whole team grow. Support Team Resilience: Contribute to a shared, collaborative on-call rotation, working as a team to support production systems, document thoughtful learnings, and keep our platform running smoothly. Shape Our Technical Future: Share your unique perspective in architectural discussions and contribute technical proposals that help our systems scale sustainably. What you'll bring A Passion for Full-Stack & AI: Deep, hands-on experience building full-stack applications, with a special focus on native AI stack development. Core Technical Comfort: A strong foundational comfort with TypeScript (React, Next.js) on the front end, paired with Python and SQL on the backend. AI Integration Experience: Experience successfully bringing AI to life in production, specifically by integrating with LLM APIs or crafting intuitive AI-powered features. Thoughtful System Design: A clear understanding of RESTful API design, database management (such as PostgreSQL or Redis), and cloud ecosystems. An Eye for Real-Time UX: Familiarity with creating smooth, real-time user experiences using streaming responses (like SSE or WebSockets) so our AI feels fluid and responsive. DevOps Awareness: Comfort collaborating on continuous integration and delivery (CI/CD), containerization (Docker), and smooth cloud deployments. Empathetic Communication: Highly developed communication skills and a natural ability to listen, share ideas, and partner effectively within a cross-functional team. Nice to Have If you have experience in any of these areas, that’s wonderful! If not, we are excited to support your learning on the job: Familiarity with agentic frameworks like LangChain or LangGraph. Exposure to building vector search or RAG-based capabilities.
