Expedia Group is a global online travel company founded in 1996. It operates a portfolio of consumer travel brands - including Expedia, Hotels.com, and Vrbo - through a two-sided marketplace that connects travellers with suppliers across accommodations, activities, and air travel. The platform spans more than 70 countries, listing over 3 million properties, 220,000 activities, and partnerships with more than 500 airlines.
The engineering challenges at Expedia Group are substantial in scale. The platform processes more than 70 petabytes of data and must match millions of travellers against a supply of millions of options in real time - across search, filtering, discovery, and booking. The core systems include booking engines, recommendation infrastructure, and marketplace technology built to operate continuously across time zones and localised markets.
Teams are distributed globally and work across the full stack of travel platform engineering: large-scale data pipelines, two-sided marketplace mechanics, cross-border product development, and consumer-facing applications used by travellers in over 70 countries. The company has been building travel technology since 1996, giving its engineering organisation a long-established foundation in a technically complex and operationally demanding domain.
