Senior Linux/Unix Systems Administrator

Responsibilities

Peraton is seeking an enthusiastic and talented Senior Systems Administrator to build on ongoing modernization efforts for the US Navy with enabling microservices to be rapidly built, tested, fielded, and integrated to container orchestration platforms through heavy use of automation tools and security processes.

We work in small-to-mid size, diverse teams with clear ownership of tasking. Engineers are trusted in solving problems and aren’t waiting for permission to execute.

U.S. Navy warfighters need your help to rapidly deliver cutting edge software solutions to the fleet for planning and executing missions for carrier strike groups conducting operations around the world. Mission planners need to collaborate in order plan for anti-surface warfare, anti-submarine warfare, ballistic missile defense, autonomous drone swarm information gain, and a wide range of other mission areas.

• Containerization & Orchestration
• Deploy and manage containerized applications using Kubernetes and other orchestration tools.
• Utilize containers (e.g., Docker) and orchestration configurations (e.g., Helm) to support microservice architectures.
• Collaboration & Problem Resolution
• Work closely with application developers, operations teams, and subject matter experts to support production applications and mission-critical software systems.
• Provide guidance, assistance, and coordination on complex issues to ensure timely resolution and seamless integration of system components.
• Support new AA installs and troubleshoot issues with existing AA instances at secure labs, aboard ships, and other customer sites.
