hackajob is partnering directly with Made Tech to hire for this role. To be considered for an interview, please make sure your application is full in line with the job specs as found below. Made Tech helps UK public sector organisations build and run better digital services. Our Cyber practice sits at the heart of that mission - working alongside government departments, agencies, and critical national infrastructure owners to improve how they detect, respond to, and learn from cyber threats. As a Lead Security Analyst, you'll be the most senior analyst on your engagement, setting the technical direction for the SOC and owning the quality of what the team produces - from detection engineering to threat-hunting to incident response. This isn't a role where you disappear into a ticket queue. You'll shape the threat-landscape narrative for your engagement, drive the detection backlog, and build the capability of the analysts around you. That means pairing on complex investigations, setting tradecraft standards, and making sure the team's detection content is version-controlled, peer-reviewed, and continuously improved - not left to age in a SIEM. You'll also be the trusted technical interface for client security stakeholders, translating what the SOC is seeing into the language that informs decisions. The UK public sector context matters here. You'll align your work to NCSC guidance, the Cyber Assessment Framework, and OFFICIAL handling requirements - not because compliance is the goal, but because those frameworks reflect the real risk environment your clients operate in. You'll engage with cross-government security communities, feed detection content and runbooks back into the Cyber practice, and help grow a bench of analysts who can operate at the same standard. Key Responsibilities Set the detection engineering standard - author, tune, and peer-review detections in KQL, SPL, EQL, or Sigma; manage the false-positive backlog; map coverage to MITRE ATT&CK; and train L1/L2 analysts to write and tune detections themselves. Own the threat-landscape narrative for your engagement - turn intelligence from NCSC advisories, sector feeds, and threat actor reporting into hunt themes, coverage gap analysis, and detection priorities that the SOC and client stakeholders can act on. Run the intelligence cycle as a managed discipline - maintain a collection plan, produce timely and rigorous intelligence products, and build feedback loops that keep the cycle honest and improving. Establish and lead security incident response practice - build playbooks, define the severity model, run exercises, and lead the team's response to significant incidents; run blameless post-mortems that the team actually learns from. Design the log and telemetry pipeline that detections run on - including bespoke application telemetry in cloud environments, not just commodity endpoint feeds; ensure the right signals are collected, parsed, and retained for both detection and investigation. Be the trusted technical interface for client security stakeholders - communicate what the SOC is detecting, investigating, and covering without losing fidelity; surface risks early and honestly, and align the team's priorities to the client's risk picture. Grow the analysts around you - pair on detection authorship and incident response as a default, set pairing as the team norm, and actively build the capability of L1 and L2 analysts through structured mentoring and coaching so knowledge isn't concentrated in one person. Contribute to the Cyber practice beyond your engagement - feed detection content, runbooks, and lessons learned back into shared practice resources; contribute to analyst assessment and hiring; and engage with public-sector security communities including NCSC CISP and relevant ISACs. Skills, Knowledge & Expertise We're looking for someone who holds one of the following, or an equivalent senior cyber operations leadership credential: Certified Information Systems Security Professional (CISSP) Certified Information Security Manager (CISM) CompTIA Advanced Security Practitioner (CASP+) Experience leading detection engineering in a SOC or similar environment - including writing and tuning detections in KQL, SPL, EQL, or Sigma, and managing coverage against MITRE ATT&CK Experience designing or improving a log and telemetry pipeline, including application-level telemetry from cloud-hosted services (AWS is a strong preference at this grade), with an understanding of how to design monitoring for failure modes and degraded states Evidence of running the intelligence cycle as a managed discipline - collection planning, production, and feedback - rather than consuming finished intelligence Working knowledge of UK government security standards and frameworks, including NCSC CAF Objective C, GovAssure, and OFFICIAL handling requirements Experience establishing incident response practice - playbooks, severity models, and exercises - not just responding to individual incidents Evidence of growing the technical capability of less experienced analysts through pairing, structured mentoring, or coaching, including setting clear goals and tracking progress over time Experience anchoring delivery on client outcomes rather than task completion - challenging the brief where it serves the client and making value visible rather than reporting effort Evidence of contributing reusable assets - detection playbooks, runbooks, templates, or accelerators - back into a practice or community, rather than leaving knowledge within a single team Tools and practices Familiarity with SOAR tooling and automation of triage and enrichment workflows Experience working in Kanban-led operating models, including managing triage queues, WIP limits, and class-of-service for incidents Experience running or contributing to skills-based technical assessments that evaluate demonstrated capability rather than credentials or years of experience Made Tech sponsors attainment of recognised cyber certifications for staff in scope. If you don't yet hold the essential credentials listed above but are working toward them - or can demonstrate equivalent capability through your experience - we'd still like to hear from you.
