• Familiarity with various networking equipment and data center infrastructure.
• Ability to thrive and work effectively in a network operations center (NOC) environment.

Key Responsibilities:

• Enhance the life-cycle of classified networks, from initial inception and design, through qualification and validation, to deployment, operation, and ongoing optimization.
• Scale systems sustainably through mechanisms such as automation, and continually evolve systems by advocating for changes that boost reliability and velocity.
• Collaborate with other team members and groups to thoroughly analyze requirements or potential problems and subsequently develop effective solutions and policy recommendations.
• Partner with internal application teams to design network infrastructure that meets both operational and stringent security requirements.
• Lead the development of production network infrastructure through the creation of published engineering design documents and specifications, which include detailed requirement analysis, engineering design, and robust solution development.
