• Act as the security SME across Dev and DevOps teams
• Conduct 1st-line cyber risk assessments and supplier assurance reviews
• Review vendor contracts with a focus on security obligations and controls
• Identify and manage security risks through to remediation
• Support compliance, audit readiness, and security documentation

Experience Required

• 3-6 years within Security Architecture or similar cyber roles
• Strong understanding of cyber risk, secure design, and vendor assurance
• Experience within OT, utilities, engineering, infrastructure, or BIM/CDE environments
• Strong stakeholder engagement and communication skills
• Comfortable working within fast-paced, globally distributed teams
