This role will take ownership of critical platform components, lead root cause analysis, and drive engineering improvements that strengthen platform availability, security, and operational performance. The Senior Platform Engineer will also provide technical guidance to junior engineers and Tier 2 support personnel while collaborating with architecture, cybersecurity, and operations teams to support mission-critical platform services.

What You Will Do

Design, deploy, configure, and sustain enterprise platform components across hybrid cloud and on-premises environments, including Kubernetes-based container orchestration platforms.
Own the technical implementation and operational health of assigned platform components, shared services, and infrastructure capabilities.
Develop and maintain infrastructure as code using Terraform, Ansible, or similar technologies to automate infrastructure provisioning and configuration management.
Design, implement, and maintain CI/CD pipelines that support secure, automated, and repeatable platform deployments.
Implement and maintain zero trust security controls, including identity-aware access, network segmentation, and least-privilege policies.
Lead technical onboarding activities for new mission tenants, applications, and shared services, ensuring integration with established platform standards and architecture.
Identify and implement improvements to platform reliability, scalability, performance, and operational efficiency.
Establish and improve observability capabilities, including centralized logging, metrics, alerting, and operational dashboards.
Serve as a senior Tier 3 escalation resource for complex incidents across compute, storage, networking, identity, and container infrastructure.
Independently troubleshoot and resolve complex production issues across Linux systems, cloud infrastructure, Kubernetes, networking, and identity and access management.
Lead root cause analysis for significant incidents, develop corrective action plans, and coordinate remediation across engineering teams, vendors, and partner organizations.
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.

Qualifications

Extensive hands-on experience operating, engineering, and troubleshooting production containerized workloads using Kubernetes or a Kubernetes-based platform.
Experience designing and supporting infrastructure across at least one major cloud environment (AWS, Azure, or a government cloud region) and hybrid cloud or on-premises environments.
Experience developing and maintaining infrastructure as code using Terraform, Ansible, or similar automation technologies.
Experience designing, implementing, and maintaining CI/CD pipelines and automated deployment processes.

Experience independently managing production incidents, problem management, and technical escalations under established service levels.

Experience providing technical guidance or mentorship to engineering or operations personnel.

Experience implementing zero trust architecture principles and security controls within enterprise cloud environments.
Experience with IT service management (ITSM) tools, including ServiceNow.
Experience implementing and maintaining observability platforms such as Prometheus, Grafana, Splunk, or Elastic.
Experience supporting Risk Management Framework (RMF) authorization activities, continuous monitoring, or continuous Authority to Operate (cATO).
