Staff Infrastructure Engineer

About Opendoor

Founded in 2014, Opendoor's mission is to empower everyone with the freedom to move. We believe the traditional real estate process is broken, and our goal is simple: build a digital, end-to-end customer experience that makes buying and selling a home simple, certain, and fast. We’ve supported over 100,000 home transactions and are just getting started.

Transforming an entire industry takes grit, curiosity, and a willingness to challenge the status quo. It takes a team of problem-solvers and builders - people who thrive on moving fast and making an impact. Whether you're passionate about infrastructure, automation, or building resilient systems at scale, there's a place for you here.

Real estate is broken. Come help us fix it.
