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

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
