Job Description:

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. Your impact will be visible. Success is measured by the real security improvements you deliver into the environment.

Job Responsibility:

  • 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

Requirements:

  • 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
