About the role

The Director, Cloud & Security Engineering owns cloud and security engineering across Microsoft Azure and AWS, along with network and security architecture, identity, threat detection and incident response, and vulnerability management, and produces the technical evidence needed for audits and customer security reviews. The role also owns the business-facing side of IT: demand intake and prioritization, and rolling roadmaps with priority functions so requests don’t drop or get routed around IT. This role works closely with the Director of IT Operations and Infrastructure. This is a hands-on director role - leading a small senior team while staying technical enough to serve as an escalation point, with the team growing based on company needs.

Responsibilities

Cloud & Security Engineering Strategy

• Own cloud engineering across Microsoft Azure and AWS and set network and security architecture standards, including threat modeling and solution-level requirements

• Direct identity security: privileged access, MFA, conditional access, and non-human identities
• Lead threat detection and incident response - playbooks, tabletop exercises, post-incident review - and report security posture and risk to leadership

Vulnerability & Compliance

• Produce the technical evidence needed for audits and customer security reviews

Email, SaaS & AI Security

• Deep identity security experience: privileged access management, MFA, conditional access, and non-human identities
• Experience building or maturing incident response (playbooks, tabletops) and owning vulnerability management with remediation SLAs
• Hands-on familiarity with the enterprise stack - SSE/zero-trust access (e.g., Zscaler), next-generation firewalls (e.g., FortiGate), EDR, SIEM, MDM - deep enough to direct the work and back up the team
• Fluency with compliance frameworks (NIST 800-53, CMMC, or equivalent) and producing audit-ready technical evidence
• Demonstrated experience partnering directly with business functions and managing demand against real capacity
• Strong communication skills; translates security risk for leadership and IT plans for the business

Preferred Experience

• Experience in regulated industries (nuclear, defense, energy, or federal); familiarity with 10 CFR 73.54 and NRC cybersecurity requirements
• Relevant certifications: CISSP, CISM, CCSP, or equivalent
