About Mimecast
Mimecast is a leading cybersecurity company that helps organizations protect their people, data, and communications from today's most sophisticated threats. With over 42,000 customers worldwide, we analyze more than 18 billion security events daily to stop attacks before they cause harm.

This is a hands-on engineering leadership role at the heart of Mimecast's Email & Collaboration Threat Protection platform.

Cyber threats don't wait, and neither do we. You'll lead a team that moves fast, makes decisions with conviction, and delivers results.
