The Senior Security Strategist reports to the Director of Security Strategy and Innovation and helps drive enterprise security architecture governance, capability strategy, risk assessment, and security innovation.

This role extends strategic capacity. It translates security priorities into target-state capability direction, gap and redundancy analysis, and roadmap recommendations that business and technical stakeholders can act on. It operates at the security ecosystem level, not at the level of individual application, solution, or cloud deployment review.

This role shapes and helps execute security strategy in a global, fast-moving environment where security decisions must align with business goals, platform risk, and regulatory expectations.

• Prepare briefing materials, maturity assessments, and decision support content for leadership audiences.
• Track strategic initiatives, capability gaps, and roadmap commitments to support program execution and follow-through.

• Identify capability gaps, overlaps, and redundancies across the security portfolio, and recommend what to add, enhance, consolidate, or retire.
• Shape and maintain the strategic roadmap for security capabilities, aligned to business needs, risk priorities, and technology trends.
• Ensure the overall security architecture evolves coherently, rather than reviewing individual applications, solutions, or cloud deployments, which sit with the solution and operational architecture function.
• Apply structured analysis using frameworks such as ISO 27001, NIST, and MITRE ATT&CK to support capability and roadmap decisions.

• Help define the operating model for strategic initiatives, including how capabilities move from strategy into ongoing operations.
• Develop RACIs and end-to-end process definitions that span the teams involved in running each capability.
• Translate target-state capability decisions into clear ownership, sequencing, and dependencies for the teams that execute them.

• Support the evaluation of new security technologies, AI-enabled tools, automation opportunities, and process improvements relevant to…
