Software Engineer - Identity and Access Management (IAM)

About Opendoor

Founded in 2014, Opendoor's mission is to empower everyone with the freedom to move.

We have assembled a dedicated team with diverse backgrounds to support more than 100,000 homes bought and sold with us and the customers who have selected Opendoor as a trusted partner in handling one of their largest financial transactions. But the work is far from over as we continue to grow in new markets. Transforming the real estate industry takes tenacity 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 transform a complicated process into a simple one. So where do you fit in? Whether you're passionate about real estate, people, numbers, words, code, or strategy - we have a place for you. Real estate is broken. Come help us fix it.
