6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Reduction in Critical Vulnerabilities

The number of high-severity vulnerabilities identified in production systems that remain unpatched or unmitigated.

Target · Reduce critical vulnerabilities by 25% quarter-on-quarter in your assigned domains.

If we started the quarter with 20 critical vulnerabilities in the cloud environment you own, we'd expect to see that drop to 15 by the end of the quarter, with a clear plan for the remaining ones.

Security Design Review Acceptance Rate

The percentage of new system or application designs that successfully pass your security review without requiring major re-architecture.

Target · Achieve an 85% acceptance rate for security designs within the first review cycle.

You review 10 new product designs this quarter. 9 of them get your security sign-off with only minor tweaks, meaning 1 didn't meet the bar and needed a rethink.

False Positive Reduction in SIEM/EDR

The rate at which our security tools generate alerts that turn out to be benign, requiring manual investigation.

Target · Reduce false positive rates by 30% in key detection rules within 6 months.

If a particular EDR rule was generating 100 false positives a week, we'd expect you to tune it down to 70 or fewer, freeing up the SOC team's time.

Security Automation Coverage

The percentage of routine security tasks (e.g., evidence collection, initial incident enrichment) that are automated.

Target · Automate 20% of manual security tasks in your domain within the next year.

You identify 5 tasks that take 2 hours each per week. Automating one of those tasks completely would be a 20% automation gain.

Architectural Soundness

How well your designed security solutions integrate with existing systems, scale for future growth, and meet business requirements without unnecessary friction.

Your designs are consistently adopted by engineering teams without significant pushback. Solutions are robust under load and don't introduce new operational headaches. You're proactively consulted on new system architectures, not just brought in at the end.

Mentorship and Technical Leadership

Your ability to guide and develop junior and mid-level engineers, sharing your expertise and helping them grow their skills.

Junior engineers actively seek your advice and feedback. They show measurable improvement in their technical skills and problem-solving abilities. You lead technical discussions effectively and help unblock the team when they're stuck. You're seen as a trusted technical advisor.

Proactive Threat Hunting & Risk Identification

Your initiative in actively searching for threats and identifying potential risks before they become incidents, rather than just reacting to alerts.

You regularly present findings from threat hunts. You identify new attack vectors or misconfigurations that weren't picked up by automated tools. You contribute to our internal threat intelligence and risk register with actionable insights.

Cross-Functional Influence

Your ability to influence and gain buy-in from non-security teams (e.g., Product, Engineering) for security best practices and architectural changes.

Other teams actively seek your input early in their design phases. You can clearly articulate security risks in business terms. You successfully negotiate security requirements without being seen as 'the department of no'.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy

Solving Complex Puzzles

You'll be happiest when you're dissecting a new threat, reverse-engineering an attack chain, or designing a robust defence for a tricky system. The harder the problem, the more engaged you'll be.

Spending an afternoon deep-diving into network flow logs to understand how an attacker moved laterally, rather than just blocking an IP.

Building and Protecting

You get satisfaction from seeing your architectural designs implemented and knowing they're actively protecting the organisation. It's about creating something secure and resilient.

Successfully rolling out a new Zero Trust policy that significantly reduces our internal attack surface, and seeing the positive impact on our security posture.

Mentoring and Guiding

You enjoy sharing your knowledge, helping junior engineers grow, and leading technical discussions. You'll find satisfaction in seeing your team members develop under your guidance.

Spending time with a junior engineer, walking them through a complex vulnerability assessment and explaining the nuances of threat prioritisation.

What frustrates people

Alert Fatigue: Drowning in thousands of low-fidelity alerts from a poorly tuned SIEM, making it easy to miss the one that actually matters, despite your best efforts to tune them.
The 'Department of No': Constantly being perceived as a blocker to innovation because you have to say 'no' to insecure applications or rushed deployments, even when you're trying to be helpful.
Management Risk Acceptance: Spending weeks proving a critical risk, only to have senior management formally accept it because the fix is 'too expensive' or 'slows down business' (even if you disagree).
Patching Politics: The endless battle with infrastructure or product teams who resist patching critical vulnerabilities on production systems because they fear it will cause downtime, often delaying essential fixes.
Blame Without Context: Being asked 'How did this happen?' after an incident, when your budget requests for the exact tool or headcount that would have prevented it were denied for the last three years. It's frustrating, but you'll learn to manage it.

What this role does not give you

A purely reactive 'firefighting' role – we need you to be proactive and strategic.
An environment where security is always the top priority without negotiation.
A role with zero ambiguity or messy, incomplete information.
A quiet, isolated role where you don't have to talk to other teams much.

8Who you work with

This role directly shapes our security posture, influencing how we design, build, and operate all our IT systems. Your architectural decisions will determine our resilience against cyber threats and our ability to meet regulatory obligations. Get it right, and we save millions in potential breach costs and reputational damage. Get it wrong, and the consequences are pretty severe, frankly.

9What you need before you start

Not a wish list. The things you would be expected to already have.

A solid 5+ years of hands-on experience as a Senior IT Security Engineer, where you've owned significant security projects and led incident responses.
Demonstrable experience in designing and implementing security solutions across at least two major domains (e.g., cloud, network, application).
A proven track record of mentoring junior engineers and leading technical initiatives.
Strong scripting skills in Python or PowerShell, with examples of security automation you've built.
Experience with enterprise-level SIEM/EDR platforms and advanced threat hunting techniques.

10What to practise next

Where the job is going, and what to do about it starting this week.

Security Chaos Engineering

Just like chaos engineering tests system resilience, security chaos engineering intentionally injects failures or attacks to test our security controls and incident response capabilities in a controlled manner. It's about finding weaknesses before attackers do.

Game Days & Red Team Exercises · Automated Security Testing · Measuring Security Resilience

This week: Read 'Chaos Engineering' by Richard Cook and Nora Jones.
This month: Propose and plan a small-scale security 'game day' for a non-critical system.
Month 2: Research open-source security chaos engineering tools and experiment with one.
Month 3: Present a proposal for integrating security chaos engineering into our annual security testing programme.

Quick win: Identify a non-production environment and simulate a simple attack (e.g., port scan) to see if it's detected by our SIEM.

11Staying current once you are in

What people here do to keep up

Regularly attend industry conferences (e.g., Black Hat, DEF CON, RSA Conference) to stay current on emerging threats and technologies.
Actively participate in security communities and forums (e.g., local OWASP chapters, B-Sides events) to share knowledge and network.
Contribute to open-source security projects or develop personal security tools/scripts.
Pursue advanced training in areas like malware analysis, reverse engineering, or advanced persistent threat (APT) emulation.
Mentor junior security professionals and actively share your knowledge through internal workshops or presentations.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, security engineering can be a demanding gig, full of repetitive tasks and mountains of data. But what if you could offload a significant chunk of that grunt work to AI? We're not talking about replacing you; we're talking about making you incredibly more effective and freeing you up for the truly strategic stuff.

Our AI Productivity Hub is designed specifically for technical roles like yours. It's not just a buzzword; it's a suite of practical tools and integrations that will help you automate the tedious, accelerate your analysis, and get to insights faster. Imagine having an AI assistant that understands security concepts and can help you tackle the daily grind.

Alert Triage Automation

Use AI-powered SOAR platforms to automatically investigate, enrich, and close those low-level, high-volume alerts (think impossible travel, brute force attempts). This frees up your valuable human analyst time for complex threat hunting. Honestly, it's a game-changer for alert fatigue.

Anomaly Detection Acceleration

Leverage User and Entity Behaviour Analytics (UEBA) to spot subtle deviations from normal activity that signature-based rules just can't catch – like an admin account accessing unusual data at 3 AM. This drastically shortens the 'dwell time' of an attacker in our network, which is critical.

Threat Intelligence Synthesis

Use Large Language Models (LLMs) to rapidly summarise new CVE disclosures, threat actor reports, and dark web chatter. You can ask it to 'Explain the business impact of this vulnerability and list immediate mitigation steps for our tech stack,' saving you hours of manual research.

Reporting & Communication Generation

Draft initial versions of incident post-mortems, executive summaries, or security awareness bulletins. Just give the AI the technical details and ask it to 'Write a 3-paragraph summary for a non-technical audience.' It's not perfect, but it's a brilliant starting point and saves a ton of time on documentation.

Common questions

How do you become a Lead IT Security Engineer?

Common routes in include Senior Security Engineer (Internal Promotion) (3-5 years as a Senior Engineer), Security Consultant (External Hire) (8-12 years in various consulting roles) and DevSecOps Lead (External Hire) (8-12 years with a strong focus on secure development and automation). Times vary with prior experience.

Where can a Lead IT Security Engineer progress to?

This role can lead on to Principal Security Engineer (IC Path) (3-5 years) and Security Engineering Manager (Management Path) (2-4 years), depending on the skills you build.
