Are you a technologist Security Engineer with a strong understanding of detection engineering?

You could be progressing your career in a senior, hands-on role at a tech driven, global Asset Manager with multiple billions of dollars under management.

Over time, you'll also contribute to initiatives including additional log sources, Microsoft 365 DLP policies, Network Access Control and wider Information Security projects aligned to frameworks such as NIST.

You'll also help to drive a shift-left approach to security, working with development teams to improve security earlier in the software development lifecycle. While the role is predominantly technical, you'll need the breadth and communication skills to contribute across the wider security function.

• You understand how detection works and are comfortable solving unfamiliar problems and can pick up new technologies quickly


• You have a good knowledge of both Windows and Linux OS


• You can script with Python, Terraform, PowerShell or similar and believe in automation


• You're collaborative with great communication and problem solving skills


• You're degree educated, having achieved a 2.1 or above from a top tier university in a STEM discipline

What's in it for you:

• Salary to £100k + bonus


• Pension


• Private medical insurance including 24 hour GP access


• Enhanced parental leave policy


• 25 days annual leave


• Ongoing training and development and financial support for courses
