Senior Software Engineer – IAM Platform
Are you passionate about building secure, scalable platforms that enable seamless integration across a large organization? Do you thrive on solving complex authentication and authorization challenges? The IAM Platform team at Alarm.com is looking for a Senior Software Engineer to help us evolve our Identity and Access Management (IAM) platform, leveraging technologies like Keycloak, OAuth2, and OIDC.
WHAT'S IN IT FOR YOU?
Collaborate with outstanding people: We have a strong focus on teamwork, and we work to create a collaborative and welcoming environment that enables our teams to excel.
Make an immediate impact: You can expect to be given real responsibility for bringing new technologies to the marketplace. You will be empowered to perform as soon as you join the team!

Be Empowered: We don’t want to micro-manage you. We barely want to tell you what to do. We want you to own stuff and bring your experience to make those products best in class.
