Senior Security Engineer (Azure / SOC / Threat Hunting)
London or Manchester (2 days per week) | Hybrid | SC Clearance required or eligible
I’m working with a highly respected, UK regulatory organisation building out their in‑house Security Operations capability following a transition away from an outsourced SOC.
This is a hands‑on Senior Security Engineer role with strong influence across architecture, ideal for someone who enjoys threat hunting, incident response, and working across Azure security tooling in a complex, regulated environment.
The Role
You’ll act as a senior escalation point across the SOC (2nd/3rd line), working closely with analysts while also contributing to the ongoing evolution of the security architecture.
This is a busy, high-impact environment where you’ll need to make rapid, informed decisions in response to threats, while proactively improving detection and response capabilities.
What You’ll Be Doing
- Acting as a technical escalation point for security incidents (2nd/3rd line)
- Leading threat hunting activities using KQL across Microsoft Sentinel
- Supporting incident response and rapid triage of security events
- Working closely with the SOC team to strengthen detection and response
- Contributing to the design and improvement of Azure security architecture
- Investigating and resolving network security‑related issues
- Driving improvements across a hybrid (cloud + on‑prem) environment
Tech Environment
- Microsoft Sentinel (well established)
- Entra ID / Active Directory (hybrid)
- Microsoft security stack (Defender, etc.)
- Hybrid infrastructure (cloud + on‑prem)
What They’re Looking For
- Strong experience in a SOC environment (2nd/3rd line / escalation level)
- Hands‑on expertise with Microsoft Sentinel + KQL (essential)
- Proven threat hunting and incident response capability
- Solid background in Azure security (not multi‑cloud)
- Strong understanding of network security principles (LAN/WAN/Wi‑Fi)
- Experience working in regulated environments (e.g. government, finance, etc.)
- Background in project‑based delivery, not just BAU
Why It’s Interesting
- Recently brought SOC in‑house — lots of opportunity to shape and improve
- Blend of hands‑on engineering + architectural input
- Exposure to a complex, regulated environment with real‑world impact
- Working with modern Microsoft security tooling in a cloud‑first (Azure) setup
If you’re a Senior Security Engineer who enjoys being close to the action but still influencing the bigger picture, this is a great opportunity to step into a high‑visibility role.
