Senior Security Engineer - Security Operations

As our next Security Engineer, you'll shape how secure software gets built at Checkatrade. You'll design the platforms, paved paths, and guardrails that let engineering teams ship fast without trading off security and use AI and automation to make secure-by-default the cheapest, easiest option every time. This isn't a checkbox security role. It's about building the rails so every team rolls forward securely.

Forget long lists, here’s what you’ll actually spend your time on :

• Design and implement scalable security controls and platform-level guardrails across our multi-cloud estate: build it once, make it the default everywhere.
• Drive a modern secure SDLC by embedding threat modelling, SAST/DAST/SCA, secrets management, and dependency hygiene directly into the developer workflow, not bolted on as an afterthought.
• Prototype and deploy AI agents that review code, triage findings, and turn vulnerability noise into actionable signals, becoming the assistant every developer wishes they had.
• Own the security of our IaC, CI/CD pipelines, and cloud platforms, making least privilege the default rather than a project.
• Partner with engineering to deliver paved paths, libraries, and tooling that make the secure way the easy way.
• Run technical security reviews for new applications and infrastructure changes, finding the issues that matter with the evidence to back it up.

It’s not about ticking every box. It’s about turning up curious, ready to crack on. You’ll do well here if you bring:

• Demonstrable experience across application security, cloud security, and modern platform engineering. You've built things, not just reviewed them.
• A strong, evidenced point of view on how agentic AI transforms code review, threat modelling, and developer enablement, with the receipts to back it up.
• Extensive hands-on experience securing complex multi-cloud environments (AWS, GCP, Azure), plus deep familiarity with Terraform, Kubernetes, and CI/CD security patterns.
• A genuine sense of developer empathy, built from sitting with engineers, watching them work, and shipping things they actually want to use.

We believe great work deserves great rewards. Here’s just a taste:

• Competitive salary + annual bonus
• Employee Share Programme
• Health, well-being and learning support
• Gym membership, Smart Tech Scheme and Cycle Scheme
• Birthday/Special day leave
• Buy & sell holiday scheme
• 1 week’s paid charity leave and much more!

How we’ll get to know each other

• Screening call with one of our Talent Acquisition Partners
• 1st stage interview with Hiring Manager - Head of InfoSec
• 2nd Stage interview with IT Manager & Director of Engineering

If this sounds like the place where you can do your best work, we’d love to hear from you, even if you don’t tick every box
