5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Incident Response Actions (e.g., system isolation, blocking IPs) Escalate to Senior Analyst or Lead for approval and execution. Execute routine actions within defined playbooks; escalate novel situations. Full authority to execute technical response actions during critical incidents; consult with Legal/Leadership on broader business impacts.
New Detection Rule Implementation (SIEM/SOAR) Propose new rules to Senior Analyst for review and implementation. Develop and test new rules; require peer review before deployment. Design, implement, and tune advanced detection rules and automation playbooks; responsible for their effectiveness and false positive rates.
Security Tool Configuration Changes Perform changes under direct supervision or follow strict runbooks. Implement standard configuration changes independently; escalate complex changes. Lead configuration changes for critical security platforms; design and architect complex integrations; make recommendations on tool optimisation.
Mentorship & Training for Junior Staff Receive guidance and training. Informally guide new joiners on basic tasks. Formally mentor 1-2 junior analysts, providing technical guidance, code reviews, and career advice. Responsible for their technical development within your domain.

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.

Mean Time to Remediate (MTTR) for Critical Incidents
The average time it takes from detecting a critical security incident to fully resolving it and restoring normal operations.
Target · Reduce MTTR for critical incidents from 30 days to 15 days.

If a critical vulnerability is identified on 1st January, and it's fully patched and verified by 15th January, that's 15 days. We track this across all major incidents.

Successful Threat Detections & Proactive Hunts
The number of high-fidelity threats identified and mitigated through proactive threat hunting activities, not just reactive alerts.
Target · Identify and neutralise 2-3 significant threats per quarter through proactive hunting.

Discovering a previously undetected persistence mechanism used by an attacker in our APAC region through a custom SIEM query, leading to its removal before any data exfiltration.

Security Control Uptime for Critical Platforms
Ensuring our core security tools (like SIEM, EDR, CSPM) are always running and collecting data as expected.
Target · Maintain 99.9% uptime for critical security platforms.

If our SIEM goes down for 8 hours in a month, that's a significant hit to our ability to detect threats, and you'll be on point to make sure it's back up and stable.

Incident Post-Mortem Quality & Action Item Closure
The thoroughness of incident reviews and the timely implementation of lessons learned to prevent recurrence.
Target · Achieve 90% closure rate of high-priority action items from incident post-mortems within agreed timelines.

After a phishing campaign, you'd ensure the recommended email gateway rule changes are deployed and verified within the fortnight, not just left on a backlog.

Technical Leadership in Incident Response
Your ability to take charge during a live incident, guiding junior analysts and coordinating with other technical teams effectively.
  • You're the first person the SOC team calls when a major incident breaks. You clearly articulate the technical steps required, delegate tasks, and maintain a calm, authoritative presence. Post-incident feedback from the SOC Manager and engineering leads consistently highlights your decisive technical guidance.
Mentorship and Knowledge Transfer
How well you help junior team members grow their technical skills and understanding of complex security concepts.
  • Junior analysts regularly seek your advice on complex queries or incident investigations. You actively run internal 'lunch and learn' sessions on new threat techniques or tools. Your code reviews for detection rules aren't just about finding errors, but about teaching best practices. We'll see junior team members taking on more complex tasks after working with you.
Proactive Threat Hunting & Detection Engineering
Your initiative in developing new detection rules and hunting for threats that our automated systems might miss.
  • You regularly propose and implement new SIEM detection rules based on emerging threat intelligence. You conduct weekly or bi-weekly proactive hunts, documenting your methodology and findings. You're not just waiting for alerts
  • you're actively looking for the needle in the haystack.
Cross-Functional Technical Collaboration
Your effectiveness in working with other technical teams (e.g., Cloud Engineering, DevOps) to implement security controls and remediate vulnerabilities.
  • Engineering teams proactively involve you in their design reviews because they trust your technical judgment. You can explain complex security issues to non-security engineers in a way they understand and act upon. You don't just point out problems
  • you help them find practical, secure solutions.

7Would you like it

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

What people enjoy
Solving Complex Technical Puzzles

You thrive on dissecting intricate malware, tracing complex attack paths through multiple systems, and reverse-engineering novel threats. The more challenging the technical problem, the more engaged you are. You love the 'aha!' moment when you finally crack a tough case.

Spending hours correlating logs from different cloud providers, endpoint protection, and network devices to piece together the full timeline of a sophisticated intrusion, ultimately identifying the attacker's method and closing the gap.

Protecting the Organisation from Real Threats

You get a genuine kick out of knowing your technical skills are directly safeguarding our company, our data, and our customers. You see the tangible impact of your work in preventing breaches and maintaining trust. It's a sense of purpose beyond just coding or configuring.

Successfully hunting down and neutralising a persistent threat actor who was attempting to exfiltrate sensitive intellectual property, knowing your actions directly saved the company from significant loss.

Continuous Learning & Technical Mastery

You're constantly learning new attack techniques, defence strategies, and security tools. You enjoy diving into technical documentation, experimenting with new technologies, and sharing your knowledge with others. Staying at the forefront of cybersecurity is a core driver for you.

Spending your personal time researching a new zero-day vulnerability, then immediately applying that knowledge to develop a custom detection rule for our SIEM before it's widely exploited.

What frustrates people
  • The '2 AM Call': Knowing your sleep can be interrupted at any moment by a critical incident that requires your immediate, full attention.
  • Alert Fatigue Burnout: Drowning in thousands of low-fidelity alerts from poorly-tuned systems, making it hard to find the real threats.
  • The 'Swivel Chair Problem': Manually copying and pasting data between different, non-integrated security tools during an incident.
  • Fighting for Resources: Constantly having to justify the need for new security tools or training, even after a near-miss incident.
  • Legacy Systems: Dealing with ancient, unpatchable systems that are critical to the business but a nightmare to secure.
What this role does not give you
  • A predictable 9-to-5 schedule (especially during incidents).
  • A role where you only focus on one specific technology or area of security.
  • A quiet, solitary environment without frequent interruptions or urgent requests.
  • A job where you never have to explain complex technical concepts to non-technical people.

8Who you work with

This role is absolutely critical for our international resilience. You're directly responsible for reducing our 'Mean Time to Detect' (MTTD) and 'Mean Time to Respond' (MTTR) for incidents that could otherwise cripple our global operations. Your work ensures our compliance with various international data protection laws, which, frankly, keeps us out of hot water with regulators and maintains customer trust. You're essentially the shield for our international digital assets.

Inside the business
  • Security Operations Centre (SOC) Team
  • Cloud Engineering and DevOps Teams
  • Legal and Compliance Departments (especially for GDPR/PIPL)
  • Regional IT Managers (EMEA, APAC, Americas)
  • Product Development Teams
Outside the business
  • External Incident Response Firms (when needed)
  • Cyber Threat Intelligence Providers
  • Law Enforcement (in case of major incidents)
  • Industry Peer Groups for threat sharing

9What you need before you start

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

  • Proven experience (5+ years) in a hands-on security role, ideally in incident response, threat hunting, or security operations.
  • Demonstrable experience with at least one major SIEM (Splunk, Sentinel) and SOAR (Cortex XSOAR) platform, including rule creation and playbook development.
  • Strong understanding of networking protocols, operating systems (Windows, Linux), and common attack vectors.
  • Experience with cloud security concepts and tools (Azure, AWS, CSPM platforms).
  • Ability to script in Python or PowerShell for automation and analysis.
  • Excellent problem-solving skills and the ability to work effectively under pressure.
  • Strong written and verbal communication skills in English.

10What to practise next

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

Advanced Threat Intelligence Correlation & Application

The volume of threat intelligence is overwhelming. Simply consuming feeds isn't enough; you'll need to become an expert at correlating disparate intelligence sources, identifying patterns, and translating raw intel into specific, actionable detection and prevention strategies tailored to our organisation and international presence.

Diamond Model of Intrusion Analysis · Threat Actor Profiling · Intelligence-Driven Defence

  • This week: Deep-dive into our current TIP (Recorded Future/Mandiant) and explore its advanced querying capabilities.
  • This month: Develop a custom threat intelligence feed focused on a specific region or industry sector relevant to us.
  • Month 2: Lead a 'purple team' exercise, using specific threat actor TTPs to test our detection capabilities.
  • Month 3: Present a brief to leadership on an emerging geopolitical threat and its specific technical implications for us.

Quick win: Regularly review our SIEM rules against the latest MITRE ATT&CK techniques, ensuring we have coverage for the most common and impactful TTPs.

11Staying current once you are in

What people here do to keep up
  • Regularly participate in cybersecurity conferences (e.g., Black Hat, DEF CON, RSA Conference) and local meetups.
  • Contribute to open-source security projects or share your threat hunting queries/scripts with the community.
  • Subscribe to leading threat intelligence feeds and cybersecurity research publications.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, cybersecurity is a constant battle, and the bad guys aren't sleeping. You're probably drowning in alerts, logs, and manual tasks. What if you could reclaim a significant chunk of your week, focusing on high-value threat hunting and strategic defence, rather than the tedious stuff? Our AI Productivity Hub is designed to do just that.

For a Senior Security Engineer, AI isn't about replacing you; it's about making you a cyber-superhero. Imagine having an intelligent assistant that handles the grunt work, sifts through mountains of data, and even drafts your reports. This frees you up to do what you do best: outsmarting attackers and building robust defences. We're investing heavily in these tools, and we want you to use them to their full potential.

Automated Triage & Response

Use AI within our SOAR platform (like Cortex XSOAR) to automatically investigate, enrich, and even close low-level alerts – think brute-force login attempts from known bad IPs. This means fewer false positives hitting your queue and more time for actual threats.

Anomaly & Behaviour Analysis

Leverage AI/ML-driven User and Entity Behaviour Analytics (UEBA) to detect subtle, anomalous patterns that signature-based rules would completely miss. Picture an admin account accessing unusual data at 3 AM – AI can flag this in minutes, not days.

Geopolitical Threat Summarisation

Use an AI assistant to scan and summarise hundreds of daily threat intelligence feeds, news articles, and dark web forums. It'll highlight threats specific to our industry and international locations, giving you targeted, actionable intelligence without the manual grind.

Incident Report Drafting

Utilise generative AI to create the first draft of your incident post-mortem reports or technical summaries for engineering leads. Translate complex technical data into clear, concise business language, saving you hours of writing and ensuring consistent communication.
