About the Role

Peraton is seeking a Platform Engineer Subject Matter Expert (SME) to provide senior technical leadership for the operation, engineering, and sustainment of a mission-critical enterprise software platform supporting an Intelligence Community customer. The platform delivers a standardized developer and user experience across multiple classified enclaves, leveraging a zero trust, hub-and-spoke architecture.

This role will guide platform reliability, automation, infrastructure optimization, and operational excellence while ensuring engineering solutions align with enterprise architecture, security requirements, and mission needs.

In addition to hands-on technical leadership, the SME will serve as a shift lead, coordinating engineering and operational activities, mentoring technical personnel, and driving resolution of enterprise-wide issues. The SME will work closely with program leadership, architecture, cybersecurity, and partner organizations to ensure the platform remains secure, resilient, and available to mission users.

What You Will Do

Establish technical direction and engineering standards for the deployment, operation, and sustainment of enterprise platform infrastructure and shared services.
Lead the design, implementation, and optimization of platform capabilities across hybrid cloud and on-premises environments, including Kubernetes-based container orchestration platforms.
Provide technical oversight of infrastructure as code, configuration management, automation, and CI/CD pipeline capabilities to ensure secure, scalable, and repeatable deployments.
Guide implementation and sustainment of zero trust security controls, including identity-aware access, network segmentation, and least-privilege policies.
Oversee technical onboarding and integration of mission tenants, applications, and shared services across the enterprise platform.
Evaluate platform architecture, engineering practices, and operational processes to identify opportunities to improve availability, scalability, resiliency, security, and performance.
Serve as the senior technical escalation authority for complex platform incidents involving compute, storage, networking, identity, cloud infrastructure, and container orchestration.
Lead major incident response activities, coordinating technical resources, engineering teams, vendors, and partner organizations to restore mission services within established service levels.
Direct root cause analysis and corrective action efforts for significant incidents, ensuring systemic issues are addressed through engineering improvements and automation.
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.
