• Proven ability to engage and influence C-suite and board audiences with credibility and humility

Responsibilities

• Act as a trusted advisor to CISOs, CTOs, and board-level stakeholders at our top strategic accounts across the Americas — helping them build and mature their human risk management programmes
• Guide customers through insider risk strategy, Incydr deployment, AI agent risk, and enterprise risk frameworks - translating the Mimecast platform’s capabilities into measurable business outcomes
• Support customers through audits, regulatory examinations, and compliance programmes across a fragmented regional landscape (SOC 2, HIPAA, GLBA, NYDFS, PIPEDA, and more)
• Be the first call when a customer has a security problem - whether or not it directly relates to our products. Run toward the problem, not away from it
• Represent Mimecast at major North American security conferences - RSA Conference, Black Hat USA, Gartner Security & Risk Management Summit, and sector-specific FSI and government events - advancing the human risk narrative in markets we must win
• Author whitepapers, research reports, and opinion pieces on human risk, insider threat, AI security, and the evolving threat landscape - contributing to Mimecast’s State of Human Risk research programme
• Build and sustain a credible public profile across North America that extends the Global Field CISO’s reach and reinforces Mimecast’s position as the human risk authority in the region

• Support land-and-expand motions by deepening relationships within existing accounts and surfacing opportunities to expand Mimecast platform adoption
• Log all advisory-linked opportunities in CRM to build the evidence base for Field CISO ROI - and to demonstrate how security advisory translates to customer outcomes
• Feed structured customer insights back to product and engineering - surfacing gaps in human risk capabilities, Incydr controls, AI governance features, and secure-by-default configurations
• Advocate for reductions in customer audit and compliance toil by pushing for product changes that make evidencing conformance easier - this is Make Things Better in action
• Contribute to the Mimecast CISO Customer Advisory Board (CAB) and regional CISO community events, building a customer community that values Mimecast as a long-term security partner
