Splunk Security Specialist - Contract - Needed - 6 Months - London based - Financial services experience needed.

Build detections. Break threats. Level up SOCs.

We need Splunk Specialist to lead end‑to‑end Splunk ES engagements for enterprise clients. This is a delivery first contract role, designing detections, tuning alerts, and building dashboards that SOC teams actually use.

* Write sharp SPL for threat detection and hunting
* Map detections to MITRE ATT&CK
* Onboard, normalise and enrich logs across Windows and Linux
* Create clear, operational dashboards for SOC teams
* Support automation and orchestration initiatives (SOAR exposure a plus)
* Use Python and PowerShell to automate and enrich workflows
* Work closely with SOC, IR and engineering teams
* Coach junior engineers when needed - no people management fluff

What We're After
* Strong hands-on Splunk Enterprise Security experience
* Proven delivery on complex, client-facing cyber projects
* Solid SOC knowledge (IAM, incident response, detection engineering)
* Sharp analytical mindset
* Confident stakeholder communication
* Eligibility to work in the UK

Nice to Have
* SOAR or UEBA experience
* Large-scale cyber or infrastructure programme experience
* Enjoys knowledge sharing and mentoring


  • Proper hands-on Splunk work
    * High-impact projects
    * Trusted delivery ownership
    * Real influence on detection strategy
