Senior Platform Engineer

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.
