We’re a proud industry pioneer with over 20 years of experience accelerating the ad technology evolution. Our proprietary tech is trusted by some of the world’s largest brands and media owners and plays a crucial role in keeping the internet open, accessible, and largely free.

We process more than 550 billion real‑time auctions every day (in comparison, Google processes 8.5 billion searches per day) with ultra‑low latency. Our platform is vertically integrated from servers to networks and runs primarily on our own metal and cloud infrastructure. This end‑to‑end infrastructure is designed to provide both stability and agility, enabling us to adapt quickly as the market evolves.

At the core of it all is our engineering‑first culture. Our engineers tackle internet‑scale problems across tight‑knit, global teams. From moving petabytes of data and optimizing with AI to making real‑time infrastructure decisions, Indexers have the agency and influence to shape the future of advertising. We move fast, build thoughtfully, and stay grounded in our core values.

We’re looking for a Staff Engineer, Data Systems to join our team and help build and maintain the next generation of big and small data solutions at Index Exchange.
