Role Purpose & Context

Role Summary

The Global Head of Security Manager is responsible for leading, shaping, and delivering a critical security function across our global operations. This could be anything from our Security Operations Centre (SOC) to Governance, Risk, and Compliance (GRC), or even our Cloud Security programme. You'll be the one making sure your team is effective, efficient, and constantly improving, which directly impacts our overall risk posture and ability to operate safely. Day-to-day, you'll be juggling people management, strategic planning, budget oversight, and making sure your function delivers on its promises. You're not just reacting to threats; you're building the capability to prevent them. When this role is done well, our organisation runs smoothly, our data is protected, and our customers trust us. When it's not, we're looking at potential breaches, regulatory fines, and a serious hit to our reputation. The challenge is balancing the daily grind with long-term strategic goals, all while keeping your team motivated and effective. The reward, honestly, is knowing you're protecting the business from some pretty nasty stuff.

Scope: This role directly shapes our organisational security strategy and capability within its domain. Your decisions will influence how we protect our assets, manage risk, and respond to incidents globally. You'll own a significant P&L, typically in the range of £500K-£2M, meaning you're directly responsible for how we invest in and manage security resources. You'll be building the teams and processes that keep us safe, which is pretty fundamental to our business.

Primary Traits

Supporting Traits

Primary Motivators

  1. Motivator: Making a Real Impact
  2. Daily: You'll get a kick out of seeing your team's work directly prevent incidents, improve our security posture, and enable the business to innovate safely. You'll be driven by the measurable reduction of risk and the knowledge that you're protecting our 'crown jewels'.
  3. Motivator: Building & Leading High-Performing Teams
  4. Daily: You'll thrive on mentoring your direct reports, helping them grow their careers, and fostering a collaborative, learning-focused environment. Seeing your team succeed and develop new capabilities will be a major source of satisfaction.
  5. Motivator: Solving Complex, Strategic Problems
  6. Daily: The challenge of translating technical threats into business risks, designing enterprise-wide security programmes, and navigating organisational politics to get things done will energise you. You're not just fixing bugs; you're solving puzzles that protect the entire company.

Potential Demotivators

Honestly, this job isn't always glamorous. You'll spend a fair bit of time trying to prove the ROI of preventing a disaster that hasn't happened yet—that's the 'Budget Justification Fatigue' we all know. Expect to discover the marketing team has been using a new, unsanctioned SaaS platform to store customer PII for the last six months (that's 'Shadow IT Surprises'). You'll likely be tasked with securing a newly acquired company that has a completely different tech stack, zero documentation, and a 'move fast and break things' culture (hello, 'M&A Integration Nightmares'). Your SOC team might be drowning in thousands of low-fidelity alerts, and you'll worry that the critical one will be the needle in the haystack they miss ('Alert Fatigue Burnout'). You'll constantly be fighting the perception that Security's only purpose is to slow down innovation and block projects, rather than enabling the business to take risks safely (the 'Department of No' syndrome). And yes, you'll often be brought into a major new product launch a week before go-live and expected to 'bless' the architecture with no time for a proper security review ('Why weren't we involved sooner?').

Common Frustrations

  1. Getting buy-in for security initiatives from teams who see it as 'extra work'.
  2. Dealing with legacy systems that are impossible to patch or properly secure.
  3. The constant battle against 'alert fatigue' and making sure your team isn't burnt out.
  4. Translating complex technical risks into language that non-technical executives understand and care about.
  5. The 'We Accept the Risk' button – when security flags a critical risk, but a business unit leader formally accepts it in writing to meet a deadline, shifting liability.

What Role Doesn't Offer

  1. A quiet, predictable 9-to-5 job with no surprises.
  2. The ability to make unilateral decisions without needing to influence others.
  3. A role where you're solely focused on deep technical work without people management.
  4. A guaranteed 'thank you' for preventing a breach that never happened.

ADHD Positives

  1. The fast-paced, often unpredictable nature of security management, especially during incidents, can be highly engaging and stimulating.
  2. The need to quickly pivot between strategic planning, team management, and incident response can suit a mind that thrives on variety and novelty.
  3. Hyperfocus can be a superpower when deep-diving into complex security challenges or strategic programme design.

ADHD Challenges and Accommodations

  1. Managing multiple long-term strategic programmes and detailed budget oversight might require strong organisational systems and tools (e.g., robust project management software, dedicated executive assistant support).
  2. The volume of administrative tasks inherent in a management role could be challenging; we can explore delegating routine tasks or using AI tools for drafting reports.
  3. We can work with you to structure your day, use visual aids for project tracking, and ensure clear, concise communication to help manage workload and focus.

Dyslexia Positives

  1. Often brings exceptional spatial reasoning, pattern recognition, and 'big picture' strategic thinking—all crucial for understanding complex threat landscapes and designing robust security architectures.
  2. Strong verbal communication skills can be a huge asset in influencing stakeholders and leading incident response efforts, where clarity under pressure is key.

Dyslexia Challenges and Accommodations

  1. The heavy reliance on written reports, policy documents, and board presentations can be demanding. We'll support you with access to proofreading tools, AI-powered drafting assistants, and administrative support for critical documents.
  2. We encourage the use of visual tools (diagrams, mind maps) for strategic planning and communication, and we value verbal presentations as much as written ones.
  3. We can provide access to assistive technologies like text-to-speech software and offer flexible approaches to documentation and reporting.

Autism Positives

  1. A strong logical and analytical mind, essential for dissecting complex security problems, designing robust controls, and understanding intricate systems.
  2. A dedication to accuracy and detail can be invaluable in GRC, policy development, and ensuring compliance.
  3. Direct, honest communication is highly valued, especially in a leadership role where clarity is paramount.

Autism Challenges and Accommodations

  1. Navigating complex organisational politics and unspoken social cues can sometimes be challenging. We'll ensure clear expectations for stakeholder engagement and provide support in navigating these dynamics.
  2. The need for frequent, often spontaneous, social interaction in a management role might require specific strategies. We can agree on preferred communication channels and meeting structures.
  3. We offer a clear, structured environment where expectations are explicit, and we're open to discussing any specific sensory or communication needs to help you thrive.

Sensory Considerations

Our main office environment is a typical open-plan space, which can sometimes be a bit noisy with team discussions and general office buzz. That said, we do have plenty of quiet zones, focus pods, and meeting rooms available for focused work or private calls. Visually, it's a modern, well-lit office. Socially, it's a collaborative culture, but we're flexible with communication styles and understand that everyone has different preferences for interaction. We're happy to discuss any specific needs you might have to make your workspace comfortable and productive.

Flexibility Notes

We believe in flexibility. While this is a leadership role that requires presence and collaboration, we're open to hybrid working arrangements, balancing office time for team connection and strategic meetings with remote work for deep focus. We'll work with you to find a rhythm that suits both you and the team.

Key Responsibilities

Experience Levels Responsibilities

  1. Level: Principal/Manager (L5)
  2. Responsibilities: Set the vision and strategy for your assigned security function (e.g., SOC, GRC, Cloud Security), making sure it aligns with the overall business goals and risk appetite. This means looking 12-24 months ahead, not just reacting to today's threats.
  3. Build and lead a high-performing team of security professionals, which includes hiring, mentoring, performance management, and career development. You're responsible for their growth and making sure they're delivering top-notch work.
  4. Own the P&L for your security function, managing a budget typically between £500K and £2M. This involves making smart investment decisions in tools, training, and personnel, and justifying those costs to senior leadership.
  5. Design and implement robust security programmes and processes within your domain. This isn't just about tweaking existing things; it's about transforming how we operate to improve our security posture significantly.
  6. Represent the organisation externally on security matters related to your function, whether that's with auditors, key vendors, or at industry conferences. You'll be a visible leader in your field.
  7. Drive continuous improvement across your function, regularly reviewing performance metrics, conducting post-mortems after incidents, and making sure lessons learned are actually implemented. We expect you to challenge the status quo.
  8. Act as a trusted advisor to executive peers and senior leadership on security risks and opportunities within your area. You'll translate complex technical issues into clear business implications, helping them make informed decisions.
  9. Supervision: You'll be largely self-directed, with quarterly objectives set with the Director of Security. We trust you to get on with it, but you'll have regular check-ins to discuss progress, challenges, and strategic alignment. Think of it as a partnership, not micro-management.
  10. Decision: You'll have full authority for your function, including budget allocation up to £500K (with oversight for larger sums), hiring and firing decisions for your team, and vendor selection up to £100K. Organisational design within your function is yours to shape. Any board-level decisions or significant external commitments will require alignment with the Director of Security or CISO, but you'll be the one presenting the case.
  11. Success: Success looks like a highly effective, motivated team that consistently meets its security objectives, a measurable improvement in our security posture within your domain, and strong relationships with internal and external stakeholders. You'll be seen as a leader who delivers and genuinely protects the business.

Decision-Making Authority

Save 15-20 Hours Weekly: Supercharge Your Security Leadership with AI

Let's be real, a Global Head of Security Manager has a lot on their plate. You're balancing strategic vision with operational oversight, managing people, and trying to stay ahead of the next big threat. What if you could reclaim a significant chunk of your week, not by working less, but by working smarter? That's where AI comes in.

ID:

Tool: Automated Alert Triage & Investigation

Benefit: Imagine your SOC team getting thousands of alerts daily. AI-powered platforms ingest these from all your tools (EDR, SIEM, Cloud), automatically investigate them by enriching with context, and dismiss 80% as false positives. This turns thousands of alerts into a handful of actionable incidents, freeing your team for proactive threat hunting and reducing burnout. For you, it means fewer escalations and a more efficient team.

ID:

Tool: AI-Powered Risk Quantification

Benefit: Trying to translate technical vulnerabilities into financial terms for the board can be a headache. AI models can analyse internal vulnerability data, threat intelligence, and business context to tell you, 'This vulnerability has a 15% chance of causing a £2M loss this year.' This gives you a defensible, data-driven narrative for budget and resource allocation, making your arguments much stronger.

ID:

Tool: Automated GRC & Compliance Mapping

Benefit: Audit prep is soul-crushing, right? AI tools continuously scan cloud configurations and system settings, automatically collecting evidence for compliance frameworks like ISO 27001 or SOC 2. It maps a single piece of evidence to multiple controls, eliminating repetitive work. For your GRC function, this means drastically reducing manual labour and accelerating audit readiness.

ID:

Tool: Generative AI for Board Reporting

Benefit: Drafting that crucial board deck can eat up hours. Feed raw data (incident metrics, risk reports, project status) into a secure, internal generative AI model. Ask it to 'Draft a 3-slide executive summary for the board focusing on risk reduction and ROI of our security investments.' It provides a solid first draft in seconds, allowing you more time to refine the strategic message.
