About HTS Media
HTS Media is Hopper’s advertising and media division, built to help travel brands, destinations, and suppliers connect with travelers at scale.
We power advertising placements across Hopper’s app and through our B2B partner network, which includes global brands like Capital One Travel and TripAdvisor.
Our mission is to build the travel industry’s leading retail media network, turning advertising into a major driver of profitability for Hopper and our partners, much like Instacart, Uber, and Amazon have done in their sectors.

This is a mission‑critical role where your work will directly impact platform performance, advertiser success, and Hopper’s bottom line.
You will tackle complex challenges inherent to the ad tech space, from optimizing our real‑time bidding (RTB) logic to ensuring millisecond response times under heavy load. You will serve as a technical leader, mentoring other engineers, driving architectural decisions, and setting the standard for high‑quality, scalable code.
