Your Impact

Do you want to develop your engineering career while helping operate, maintain and improve secure platforms that protect national security? At Leonardo, our Platform Engineers provide the hands-on engineering and operational support that keeps critical customer services secure, available and fit for purpose.

Your work at Leonardo UK will see you solve customer and service problems in an agile, innovative and team-centric manner. This is an operational role supporting highly controlled environments, requiring regular on-site working and close collaboration with senior engineers, service management, security and customer teams.

Leonardo UK is seeking a Platform Engineer to join the Cyber & Security Solutions Division team. This role is focused on operating, maintaining and improving platform and systems engineering solutions that underpin critical defence, government and public sector services.

What you will do as a Platform Engineer

• Operate, maintain and support secure Windows, Red Hat Enterprise Linux and virtualised platforms within highly controlled environments.

• Deliver assigned operational engineering tasks, including deployments, configuration changes, monitoring, patching, upgrades, backup and service enhancements.

• Support incident, problem and change activity, investigating technical issues and contributing to recovery and root-cause analysis.

• Maintain secure configurations, platform baselines, support documentation, runbooks and knowledge articles.

• Troubleshoot platform, network, integration and service issues, escalating complex problems where appropriate.

• Contribute to low-level designs, implementation plans, testing, technical evidence and operational documentation.

• Work with Senior and Principal Engineers to support operational readiness, service acceptance and transition into business-as-usual support.

• Contribute to continuous improvement through automation, reusable engineering patterns and improvements to support processes.

• Share knowledge with colleagues and support the development of wider team capability.
  

What you’ll bring

• A solid grounding in IT infrastructure, with hands-on experience in system administration, engineering or technical support.
• The ability to work independently on defined activities while collaborating effectively within a wider operational engineering team.
• A disciplined service mindset, with attention to detail and a willingness to take ownership of assigned issues and tasks.
• A proactive approach to learning new technologies and developing broader platform engineering capability.
• The ability to communicate clearly with technical, service management, security and customer stakeholders.

Core areas (must have):

• Hands-on experience with Windows Server and/or Red Hat Enterprise Linux administration and support.
• Experience with enterprise virtualisation technologies, such as VMware or Hyper-V.
• Networking fundamentals including TCP/IP, DNS, DHCP, routing and firewalls.
• Experience supporting infrastructure or platforms within a controlled, regulated or secure environment.
• Infrastructure lifecycle activities including deployment, configuration, monitoring, patching, upgrading, backup and sustainment.
• Understanding of incident, problem, change and configuration management within an ITIL-aligned service environment.
• Awareness of cyber security controls, system hardening and vulnerability remediation.
• Troubleshooting and fault-finding across integrated infrastructure and platform services.
• Creation and maintenance of technical documentation, such as support guides, runbooks and configuration records.

Desirable:

Experience in one or more of the following areas would be highly desirable:

• VMware Cloud Foundation, including vSphere, vSAN, NSX or VMware Aria.
• Automation or scripting using PowerShell, Bash, Python, Ansible or Terraform.
• Privileged Access Management, including CyberArk or comparable technologies.
• Public Key Infrastructure, certificate lifecycle management or trust services.
• Cross-domain solutions, secure data transfer or controlled data flows across trust boundaries.
• DevOps, DevSecOps, CI/CD pipelines or Infrastructure as Code.
• Active Directory, identity services and wider enterprise integrations.
• Security monitoring, SIEM, endpoint security or integration with SOC tooling.
• Cloud platforms such as Microsoft Azure or Amazon Web Services.
• Containerisation platforms such as Kubernetes or Docker.
• Relevant Microsoft, Red Hat, VMware, ITIL, cyber security or cloud certifications.

Candidates are not expected to have experience in every area. We are particularly interested in capable operational platform engineers who have a sound technical foundation, bring experience in one or more relevant domains and are keen to develop across the wider secure-service environment.
