Senior Frontend Engineer

About the role

As a Senior Frontend Engineer at Mobi, you will join a highly creative, fast-paced and fearless team tasked with building the next generation of AI-driven solutions. We're seeking a passionate and innovative Frontend Engineer to help define the next generation of intelligent customer experiences at the intersection of travel and AI. In this role, you'll build elegant, highly interactive user interfaces that power AI-driven search and recommendation systems, virtual concierge services, and data-rich dashboards for analytics and visualization. You'll collaborate closely with clients and cross-functional teams to translate user needs into beautiful, intuitive digital experiences - from concept through delivery. You'll be working on cutting-edge products that integrate with state-of-the-art AI platforms, including interactive AI assistants and app integrations based on the Model Context Protocol (MCP). This includes helping define how users interact with models and immersive AI interfaces beyond plain text - building experiences that connect ChatGPT, Claude, and other AI platforms to brand ecosystems with rich, responsive visual UIs rather than just conventional text responses. MCP Apps, a new extension of the MCP standard, enables real-time interactive components within AI chat environments, and you'll help leverage this technology to create seamless, useful tools for our customers. We work with major global brands and industry leaders to shape the search and concierge experience for their users. Some client engagements involve deep collaboration to understand unique requirements and deliver tailored solutions, while others push the boundaries of what's possible with evolving AI ecosystems. If you thrive at the intersection of bleeding-edge technologies, customer engagement, and beautifully designed front-end systems, this is your opportunity to make a major impact.
