Site Reliability Engineer

Leidos•Norfolk, VA

About The Position

The NMCI Service Management Integration and Transport (SMIT) group at Leidos seeks a Site Reliability Engineer to improve the reliability, performance, and scalability of complex distributed systems. Under the SMIT Contract, the team supports the Navy-Marine Corps Intranet core backbone, including cybersecurity services, network operations and engineering, service desk, seat support services, and data transport. This role contributes to developing robust, scalable services that operate reliably in production and to the maturity of the Site Reliability Engineering program. The engineer supports, migrates, automates, and optimizes software development and deployment processes, infrastructure as code, and cloud infrastructure. Working with SRE, development, and operations teams, the engineer creates automated testing frameworks and workflows that validate services under normal and stressed conditions, including failure scenarios. The role also maintains complex computer systems by writing code to automate releases, monitor systems, and identify and resolve problems before they affect users. The position requires supporting program execution in classified environments and the ability to access SIPRNet from an NMCI location on short notice, involving local travel. The role requires an active DoD Secret security clearance and a DoD 8570.01 IAT Level II certification before onboarding, which must be maintained while supporting the SMIT Contract.
