Identify recurring operational issues and develop automation, engineering solutions, and updated runbooks to prevent future incidents.
Coordinate incident response activities and technical escalations to ensure resolution within established service levels.
Partner with cybersecurity personnel to maintain security controls, continuous monitoring capabilities, and technical evidence supporting RMF authorization and continuous ATO.
Provide technical mentorship and guidance to Mid-Level engineers and Tier 2 support personnel, establishing consistent troubleshooting and operational practices.
Maintain technical documentation, operational procedures, and knowledge base content to support platform sustainment.
Participate in technical planning and operational coordination activities to support platform availability across the enterprise.
Participate in rotating on-site shifts and the shared after-hours on-call rotation to support continuous platform operations.

Location: This position is fully onsite in Chantilly, VA.
