Senior Information Security Engineer
I'm partnering with one of the world's leading quantitative trading firms to hire a Senior Information Security Engineer into its globally recognised security engineering team.
This isn't a SOC or Incident response role.
It's an engineering role.
If your day is primarily spent monitoring alerts, triaging incidents and following runbooks, this isn't the right fit.
The team is looking for engineers who write code, build automation, integrate security tooling and build security capabilities that scale.
They want people who naturally look for inefficiencies, automate repetitive work and solve engineering problems rather than manually operating security tools.
Security is treated as an engineering discipline here.
You'll work across AWS, Microsoft 365, identity, enterprise infrastructure and security platforms, building internal tooling, improving detections, strengthening cloud security and reducing operational overhead through automation.
You'll be joining a business where technology sits at the heart of everything they do.




You'll work alongside exceptionally strong engineers who enjoy solving difficult problems, challenging conventional thinking and building high-quality systems.
The expectation is high, but so is the prospect to make a genuine technical impact.
You'll ideally have experience with:
Security engineering
DevSecOps or infrastructure security
Python and/or PowerShell scripting and automation
AWS security, including IAM, GuardDuty, CloudTrail, Security Hub and Config
Microsoft 365 security, including Entra ID, Defender, Conditional Access and PIM
Security tooling, API integrations and workflow automation
Detection engineering, vulnerability management and security operations improvements
Windows and Linux security
Identity and access management
Enterprise networking fundamentals
This role is suited to engineers who enjoy building rather than simply operating.
If you're passionate about creating security tooling, automating manual processes and solving complex technical problems at scale, I'd love to tell you more.
