About The Position

Atos Public Safety is hiring an L3 Infrastructure Engineer to provide senior-level engineering and operational support for the Windows, Linux, and VMware infrastructure that supports Next Generation 911 (NG911) services. The engineer is the senior escalation point for complex issues not resolved by L1 or L2 support teams and works across servers, virtualization, networking, storage, security, monitoring, databases, and application dependencies to restore and maintain reliable service. The role involves administering and troubleshooting Windows Server and Linux systems, managing VMware vSphere and vCenter environments, supporting infrastructure onboarding and production readiness, and maintaining technical documentation. The engineer contributes to incident, problem, change, and major incident management, performs root-cause analysis, and recommends improvements to reliability, performance, security, monitoring, capacity, and recoverability. The position supports production, non-production, laboratory, reference, and interoperability environments. It requires collaboration with NOC, engineering, application support, security, cloud operations, service delivery, project teams, and vendors. The work environment is mission-critical; participation in maintenance outside normal business hours and on-call or escalation coverage may be required.
