Establish operational standards, technical procedures, and escalation practices to improve incident response and reduce recurring service disruptions.
Provide technical oversight of observability capabilities, including centralized logging, metrics, alerting, dashboards, and platform health monitoring.
Partner with cybersecurity leadership to ensure platform security controls, continuous monitoring, and technical evidence remain aligned with RMF authorization and continuous ATO requirements.
Provide technical leadership and mentorship to Senior and Mid-Level engineers, establishing expectations for engineering quality, troubleshooting, documentation, and operational execution.
Serve as shift lead, coordinating daily platform operations, assigning technical priorities, managing escalations, and ensuring continuity across rotating shifts.
Coordinate with program leadership and customer stakeholders on platform health, operational risks, significant incidents, technical dependencies, and recommended improvements.
Lead technical working sessions and collaborate with architecture, cybersecurity, development, and operations teams to resolve enterprise-level engineering challenges.
Maintain and improve technical documentation, operational runbooks, incident response procedures, and knowledge management practices.
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.
