Head of Linux Platform Security (Hands-on)

Back to Job Search

I have partnered with one of the world’s leading hedge funds, who are building a management layer under their security leadership and are hiring a hands-on leader to drive meaningful improvements to their Linux platform security. This is a player/coach role: you’ll lead a team, partner closely with infrastructure engineering, and get hands-on when needed to deliver hardening and security changes into production.

Responsibilities include:

 

  • Lead and develop a team focused on improving Linux OS/platform/infrastructure security.
  • Assess the current environment, identify gaps, and prioritise work that materially reduces risk.
  • Drive implementation and rollout of platform security improvements (not just designs).
  • Partner with engineering teams to ship changes safely and measurably.
  • Improve authentication and privileged workflows (e.g., MFA, modern auth patterns such as OIDC alongside legacy dependencies).
  • Use data to understand usage patterns and validate that changes are effective.

 

My client is looking for:

  • Prior people management experience (this is not a first-time manager role).
  • Deep Linux platform expertise with strong security instincts.
  • Practical experience implementing controls such as Linux security modules (e.g., SELinux/AppArmor), hardening, sandboxing concepts, and secure authentication patterns.
  • Comfortable with UNIX fundamentals and scripting (shell; basic Python helpful).
  • Strong internal communication skills: able to deconstruct problems and align engineers on what/why/how.

 

This role stands out to me as your impact will be visible. Success is measured by the real security improvements you deliver into the environment.
