Technical leadership and assurance

• Act as technical lead, discipline lead, verifier or independent reviewer on major or complex commissions, in line with competence and project governance requirements.
• Lead the definition of the security problem through asset, business-impact, threat, vulnerability, criticality and risk assessment, including articulation of risk appetite, uncertainty and residual risk.
• Lead or assure the Operational Requirements process, defining Level 1 requirements and coordinating Level 2 functional and performance requirements with relevant specialists.
• Develop, compare and justify proportionate security strategies and design options that integrate people, process, physical, electronic and digital measures.

• Ensure that security requirements are coordinated with architecture, civil, structural, building services, fire, systems, digital, operational and human-factors considerations.
• Lead interdisciplinary reviews and quality assurance of strategies, TVRAs, Operational Requirements, design deliverables, specifications, drawings, assurance plans and technical reports.
• Apply relevant legislation, standards, guidance, ethical requirements, secure information handling and security-minded approaches proportionately.

Project, commercial and client leadership

• Plan and control technical scope, programme, budget, resources, quality and risk for significant security engineering tasks, projects or portfolios.
• Build trusted relationships with senior client and project stakeholders, communicate complex security issues clearly and support informed, auditable decisions.

Growth and market support

• Convert client needs into clear technical propositions, delivery approaches, resource plans and competitive fee submissions.
• Provide technical leadership for bids, frameworks, capability statements, interviews and client presentations.
• Work with account and sector leaders to identify opportunities, shape early client conversations and demonstrate the value of security engineering within major programmes.
• Develop a credible external professional profile through client engagement, industry networks, professional bodies, publications, events and technical communities.
• Support cross-selling by connecting security requirements with wider engineering, design, resilience, programme and asset-management services.

Qualifications & Experience

• Strong technical acumen in security engineering, supported by substantial experience developing, coordinating and assuring security requirements and design solutions.
