WHY BOX NEEDS YOU?

At Box, we're looking for experienced Senior Software Engineers to join several of our backend teams.

• The Device Security team at Box is responsible for protecting access to the ICM platform by ensuring that only trusted devices can connect. Their work is crucial to maintaining Box’s security and compliance, especially as businesses require more advanced controls over user access. This team focuses on building and maintaining secure, reliable systems that support enterprise-level security needs. They collaborate closely with product, security, and infrastructure teams to develop solutions that keep Box’s platform safe from unauthorized device access.

WHAT YOU'LL DO:
