About The Position

Mimecast is looking for an Account Manager, Enterprise to own growth within an assigned portfolio of existing enterprise customers. Reporting to the Sr. Director, Enterprise Account Management, you’ll be the primary commercial owner for your accounts—identifying whitespace, driving upsell and cross-sell across Mimecast’s platform, and protecting net retention through early, proactive renewal engagement. This role is central to our shift toward a consultative, platform-led selling motion. You’ll build trusted, multi-year relationships, understand each customer’s business and security posture, and navigate complex buying processes alongside internal teams and channel partners to turn existing customers into growing ones.

Strong consultative and solution-selling skills, with the ability to connect platform capabilities to customers’ business and security needs.
Experience navigating complex, multi-stakeholder enterprise buying processes, including security reviews and procurement.

Excellent relationship-building skills and executive presence with enterprise customer stakeholders.
Experience working in a subscription-based, recurring-revenue SaaS business, ideally across multiple product lines.
