Staff iOS Engineer (Swift)

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 have assembled a dedicated team with diverse backgrounds to support more than 100,000 homes bought and sold, helping customers navigate one of their largest financial transactions with trust and ease. But the work is far from over as we continue expanding into new markets.

Transforming the real estate industry takes tenacity, creativity, and dedication. It takes problem solvers and builders. It takes a tight-knit community of teammates doing the best work of their lives, pushing one another to simplify a complex process. Whether you're passionate about real estate, technology, user experience, or data-driven solutions, we have a place for you.

Real estate is broken. Come help us fix it.
