Lead Threat Detection Engineer| London | Up to £120k + Bonus
I'm working with a leading global fintech on a senior hire into a newly established security function.
This is a hands-on role for someone who wants to go beyond responding to alerts and take real ownership of how threat detection and intelligence is built, automated and improved across a large-scale, multi-cloud environment.
You’ll be joining at a point where the core security tooling is already in place, but there’s significant scope to define what best-in-class looks like.
What you’ll be doing:
- Own and improve the threat detection lifecycle across a complex cloud estate
- Build and enhance SIEM detection rules, use cases and monitoring
- Automate manual detection and remediation processes
- Develop threat intelligence and threat-hunting capabilities
- Improve security monitoring across AWS, GCP and Azure
- Work closely with engineering teams to turn security findings into scalable technical improvements
- Review existing tooling and influence future technology decisions
- Provide technical leadership and help upskill others across the security function
What we’re looking for:
- Experience building detections rather than purely responding to SOC alerts
- Strong SIEM experience – Microsoft Sentinel, Splunk or similar
- Cloud security experience across AWS, GCP and/or Azure
- KQL, SPL or similar querying experience
- Python scripting / security automation
- Terraform / Infrastructure as Code exposure
- Experience with threat intelligence or threat hunting
- Strong ownership and stakeholder communication skills
This would particularly suit someone from a fintech, payments or financial‑services environment who wants the opportunity to shape a growing security capability rather than inherit a finished one.
