About the job

Description

Senior Security Engineer

Location: Either Melbourne or Canberra based

Predominantly onsite role

NV2 clearance required (TSPV uplift supported) and OSA required or willing to obtain it

Due to the nature of the role, you must be an Australian Citizen who holds an active NV2, be willing to uplift to TSPV security clearance, and have OSA or be willing to obtain it.

Your New Role And Responsibilities

This role sits within Leidos’s Mission Software System’s capability and will report to the Security Lead. You will be capable of operating independently within your scope, while also working closely with the broader engineering teams.

There is flexibility in the role depending on your skills and experience. As a Senior Security Engineer, you will contribute to the design, delivery and uplift of security engineering and operations functions across the environment.

Do Work That Matters

  • SIEM / SOAR platform management (e.g. Splunk), including onboarding, health checks, patching, maintenance and incident resolution
  • Security engineering across endpoint, network, gateway and related technologies
  • Vulnerability management tooling, integration and continuous improvement
  • Support incident response activities using enterprise tooling
  • Managing data ingestion, building and optimizing Search queries, developing custom dashboards and alerts for monitoring, and ensuring system reliability, security, and scalability across the enterprise
  • Provide trusted security engineering advice to internal stakeholders
  • Develop and uplift security operations system requirements
  • Participate in change review and approvals
  • Build and maintain stakeholder relationships across internal teams and external partners

What You’ll Bring To Make An Impact

You’ll ideally bring experience across a number of the following:

  • EDR / Device Control / Application Control (e.g. Trellix, Carbon Black)
  • SIEM / SOAR platforms (e.g. Splunk)
  • Vulnerability management solutions
  • Multi-Factor Authentication (MFA)
  • Identity & Access Management (IAM)
  • Privileged Access Management (e.g. CyberArk, BeyondTrust)
  • Hardware Security Modules (HSM)

You don’t need experience across all technologies, but strong capability across several of these areas is important.

We’re Also Looking For Individuals Who

  • Have a strong engineering mindset and problem-solving approach
  • Can operate independently and collaboratively
  • Are passionate about cyber security and continuous improvement
  • Are motivated to support capability uplift and mentor junior team members
  • SIEM / SOAR platform management (e.g. Splunk), including onboarding, health checks, patching, maintenance and incident resolution
