About the Team

You’ll join a team where people work with integrity, inclusion, innovation, agility, collaboration and commitment. In practice, that means sharing ownership, solving complex problems together and staying connected to the customer context, the purpose behind the work and how each role contributes to meaningful outcomes.

The Opportunity

This role is an opportunity to contribute to the Matrix Engineering Group by designing, building, supporting and accrediting large enterprise infrastructure platforms for mission-critical Federal Government environments.

In this role, you will:

• Translate customer requirements into detailed designs and supporting services for complex Platform as a Service solutions.
• Install, configure, upgrade and maintain Microsoft Windows Server and Red Hat Enterprise Linux platform services delivered through VMware environments.
• Tune system performance and use automation and infrastructure-as-code practices to streamline builds, configuration deployment, health checks and repeatable operational processes.
• Produce and maintain technical, system and operational documentation, provide specialist advice and resolve complex infrastructure issues, including hands-on support at customer sites when required.

The technical environment includes Cisco UCS, VMware Cloud Foundation, Microsoft Windows Server, Red Hat Enterprise Linux, Active Directory, DNS, DHCP, DFS, enterprise backup products, storage technologies and infrastructure-as-code practices.

• Ability to diagnose and resolve complex infrastructure issues, tune system performance and produce clear technical and operational documentation.
