This is an amazing employee-first Global FS organisation undergoing a major transformation of its cyber defence capability. This is a build-focused leadership role, not a traditional security operations position, with the mandate to design and scale a modern detection engineering function, leading a technical and cultural shift toward:
- Detection as Code
- Automated response and orchestration
- Engineering-led security delivery
- Measurable, high-fidelity threat detection
To be considered for this role, you must possess a strong background in Detection Engineering & Security Engineering, with deep experience building detection use cases within enterprise SIEM platforms. Experience implementing or working within Detection-as-Code/content-as-code models, hands-on experience with CI/CD pipelines and engineering-led delivery practices, and strong scripting or programming capability (Python, PowerShell or similar) are essential. You should have cloud-based telemetry and security tooling experience and the ability to operate across engineering, security, and operational stakeholders.
You will be tasked with building the detection platform itself, not managing alerts, where security is treated as an engineering discipline, not an operational function. This is a high-visibility role with influence across cyber, engineering, and platform teams, and you will need to define modern detection delivery at scale.
THE ROLE
- Define how detection capabilities are built, tested, deployed, and continuously improved across a complex global estate.
- Design and deliver a scalable detection engineering capability.
- Build and implement Detection-as-Code frameworks using version-controlled environments.
- Establish CI/CD pipelines for detection and automation, including testing, validation, and controlled deployment.
- Develop and optimise detection logic across Identity Cloud environments.
- Design and implement automated response workflows to reduce manual intervention and false positives.
- Align coverage to real-world threat patterns.
- Introduce and enforce engineering standards across security (code quality, testing, release management, governance).
- Partner closely with incident response teams and platform/cloud engineering teams.
- Lead, mentor, and scale a team of engineers in a globally distributed environment.
Technology environment
- Cloud-native SIEM platforms (e.g. Microsoft Sentinel / Splunk / Elastic)
- SOAR/automation tooling and playbook orchestration
- Endpoint and identity telemetry platforms (e.g. Defender / CrowdStrike / cloud identity systems)
- Cloud environments (Azure-led, with multi-cloud exposure)
- Git-based version control
- CI/CD pipelines (GitHub Actions, Azure DevOps, Jenkins or similar)
- Infrastructure as Code (Terraform / ARM / similar)
- Scripting and development (Python, PowerShell or equivalent)
Frameworks / approaches
- MITRE ATT&CK aligned detection strategy
