About Engine

At Engine , we’re transforming business travel into something personalized, rewarding, and simple. For too long, managing travel and spend has been overwhelming and fragmented — we’re here to change that. We believe the future of travel should be seamless and powered by technology that delights customers at every step. That’s why we’re building a platform that brings together corporate travel, a powerful charge card, and modern spend management in one place.

To make this vision real, we’re looking for exceptional, mission-driven people to help redefine how businesses manage and experience travel.

More than 30,000 companies already rely on Engine to support over 1 million travelers and billions in annual bookings each year. Cash flow positive with rapid growth, we pair exclusive Engine -only rates, industry-leading rewards, and intelligent automation to help businesses save money while delivering world-class personalization and convenience.

Backed by Telescope Partners, Blackstone, and Permira, Engine has been recognized as one of the fastest-growing travel and fintech platforms in North America, with honors including the Deloitte Fast 500 and Built In’s Best Places to Work.

Your Mission

You will be the senior technical leader for Groups Shopping at Engine — the team that owns how group travel organizers discover and select hotels. We are building a world class travel shopping experience, and improving our property-ranking system to better understand what an organizer is looking for. You will help drive that work, set the technical bar, and make sure we ship with high quality.

This role exists to push three things forward:

• Property ranking that earns its weight. Hotel discovery is the highest-leverage moment in the group booking funnel and historically the place where ranking has been least intelligent. Optimizing how we score, sort, and present properties — using a mix of behavioral data, response signals, fit signals, and LLM reasoning — is core to what this team is being asked to do.
• Step-change scale. Groups is heading toward an order-of-magnitude increase in volume. The systems we build this year have to deliver conversion gains that compound, hold up under multiples of today's load, and not get undone by the operational drag of fast growth.
• AI inside the product. The most interesting UX advances in Groups travel right now come from putting AI directly in the organizer's hands — embedded assistance that helps them search, compare, and decide without leaving the flow. You will help define and ship the surfaces where this happens, including the seam between the product and the AI tools that drive it

What You'll Own

• Architecture for Groups Shopping. The hotel discovery, scoring, and selection surfaces — and the integration points where ranking, search, and AI in the product come together.<
