Senior Platform Engineer

About this role

Join the Leidos Homeland Sector and contribute to a high-impact international program delivering secure, next-generation private cloud capabilities within a NATO-secured environment. These new, fully funded senior-level positions offer the opportunity to apply deep technical expertise to the design, integration, and hands-on implementation of enterprise platform infrastructure supporting a Software-Defined Data Center (SDDC).

You will help deliver secure, scalable, and automated platform services across Enterprise Core Services (ECS), Client Provisioning Services (CPS), Infrastructure as a Service (IaaS), DevOps, and Service Management Control (SMC). Working closely with infrastructure, networking, cybersecurity, and DevOps teams, you will support the full delivery lifecycle—from solution design and integration through deployment, testing, and customer acceptance.

The positions also provide an exciting international travel opportunity, with approximately 25% travel to The Hague, Netherlands, and other NATO locations as needed to support implementation activities. This is an excellent opportunity for senior professionals interested in supporting the Homeland Sector’s mission while gaining valuable experience working directly with international customers and partners on a mission-critical global program.

• Deploy and integrate enterprise platform technologies including VMware Cloud Foundation (VCF), vSphere, vCenter, ESXi, NSX, vSAN, and associated platform services.

• Collaborate with networking, cybersecurity, DevOps, and infrastructure engineering teams to integrate platform capabilities into secure enterprise solutions.

• Develop platform automation using Infrastructure as Code (IaC), Ansible, Terraform, PowerShell, or similar automation technologies to standardize infrastructure deployment and configuration.

• Integrate Commercial Off-The-Shelf (COTS) platform technologies including compute, virtualization, storage, and cloud infrastructure into secure enterprise environments.

• Design and implement enterprise virtualization, resource management, clustering, high availability, and workload optimization solutions.

• Develop and maintain platform architectures, engineering designs, implementation plans, configuration standards, build guides, and technical documentation.

• Participate in Agile development activities including sprint planning, technical reviews, engineering design reviews, and cross-functional collaboration.

• Mentor engineers and provide technical guidance on platform engineering, virtualization, automation, and infrastructure modernization best practices.

• Travel to NATO sites to install, configure, integrate, validate, test, and troubleshoot enterprise platform infrastructure while supporting deployment, commissioning, technical validation, and customer acceptance activities.

• Support infrastructure modernization initiatives, technical planning, platform strategy, and proposal development activities.

• Required Experience, Skills, and Education:

• Bachelor's degree in Computer Science, Information Technology, Engineering, or related discipline with 8–12 years of relevant experience, or Master's degree with 6–10 years of relevant experience.
