Role:

  • We are looking for a hands-on Cybersecurity Engineer to support the security of complex, mission-critical systems across both project implementation and live production environments.
  • This role combines Day 1 security implementation with Day 2 production security, giving you exposure across infrastructure security, OS hardening, DevSecOps, container platforms, vulnerability management, IAM and security operations.
  • You’ll work closely with experienced security leads, infrastructure, systems, software, DevOps and SOC teams to implement controls, resolve vulnerabilities and maintain secure, reliable platforms.


Responsibilities:

  • Implement security controls based on approved security designs and standards.
  • Perform OS patching and security hardening across RHEL/Linux and Windows environments.
  • Support remediation validation, patch tracking and security baseline compliance.
  • Apply security controls across virtualised and container platforms such as OpenShift/Kubernetes, VMware and Azure Stack environments.
  • Support Kubernetes and container security, including RBAC, secrets management, network policies and image security.
  • Integrate and operate security controls within CI/CD pipelines.
  • Work with SAST, DAST, SCA and container/image-scanning tools.
  • Review vulnerabilities and work with technical teams through remediation, validation and closure.
  • Support security-risk assessments, audit evidence and production go-live readiness.


Required Skills:

  • 3–7 years of relevant cybersecurity, infrastructure security or related technical security experience, or equivalent demonstrated capability.
  • Hands-on experience implementing security controls in project or production environments.
  • Practical knowledge of OS patching and hardening across RHEL/Linux and Windows platforms.
  • Familiarity with virtualisation or hybrid infrastructure platforms such as VMware and Azure Stack.
  • Familiarity with security technologies such as SAST, DAST, SIEM or vulnerability scanners.
  • Ability to troubleshoot security issues and work through practical solutions.
