Senior Network Engineer
About The Position
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. This senior-level role offers the opportunity to apply deep technical expertise to the design, integration, and hands-on implementation of enterprise networking solutions supporting a Software-Defined Data Center (SDDC). You will help deliver secure, resilient, and automated network infrastructure across Enterprise Core Services (ECS), Client Provisioning Services (CPS), Infrastructure as a Service (IaaS), and Service Management Control (SMC). Working closely with infrastructure, virtualization, cybersecurity, and DevOps teams, you will support the full delivery lifecycle—from solution design and integration through site deployment, testing, and customer acceptance. This position offers an exciting opportunity to work directly with international customers and technical partners, with approximately 25% travel to The Hague, Netherlands, and other NATO locations as needed to support solution integration, implementation, testing, and customer acceptance. It is an ideal opportunity for a senior engineering leader interested in advancing mission-critical cloud capabilities while gaining valuable international program experience.
