About Mobi.AI http://Mobi.AI
Mobi partners with the world's leading travel brands to create AI experiences that change how people discover and book travel.
By combining deep AI expertise with more than a decade of experience in travel commerce, Mobi helps travel brands understand what travelers want, deliver more relevant experiences, and convert AI-driven intent into direct bookings. Our technology connects the intelligence of AI with the realities of travel—integrating with the systems brands already use while creating new opportunities to engage customers throughout their journey. We're building the infrastructure that will power the next generation of travel commerce.
Working at Mobi
We believe the best ideas emerge when diverse perspectives come together, so we’re building a team that truly reflects that belief. If you’re energized by complex challenges, inspired by working alongside thoughtful teammates, and passionate about building technology that enhances—rather than replaces—what makes us human, you’ll feel right at home here.
Our work is centered on five core values
- Show up, be you. We welcome every kind of thinker, maker, and teammate: quiet or bold, methodical or messy, with all their talents and quirks. Inclusion isn’t a checkbox—it’s how we connect, grow together, and do our best work.
- Be scrappy, stay steady. We’re resilient and quick on our feet, adapting with creativity and staying grounded when things shift.
- Create transparency, collaborate better. We believe knowledge grows when it’s shared. Clear, open communication builds trust and strengthens collaboration.
- Foster community, be compassionate. We show up for our teammates, customers, and neighbors. Strong businesses grow from relationships built with care and grounded in shared effort.
- Build thoughtfully, create impact. We design for clarity, build for scale, and measure success through real-world impact.

You’ll build interactive search and recommendation experiences, virtual concierge services, and data-rich dashboards. You’ll work directly with clients, designers, backend engineers, and AI engineers to scope solutions, explain trade-offs, and iterate on what users need.
You’ll build tool-driven interfaces for AI assistants and app integrations, including Model Context Protocol (MCP) apps. The work includes streaming and partial results, authentication and session continuity, and clear loading, error, and confirmation states.
AI-assisted software development is essential to this role. You should be able to show how you use coding assistants and agents to implement, test, debug, and refine
