This role will support the deployment and sustainment of containerized workloads, infrastructure as code, CI/CD pipelines, and shared platform services while troubleshooting and resolving escalated technical issues across the enterprise. Working within a cross-functional engineering and operations team, the engineer will collaborate with senior personnel, cybersecurity staff, and Tier 2 support to deliver reliable platform capabilities to mission users.

What You Will Do

Deploy, configure, maintain, and troubleshoot platform components across hybrid cloud and on-premises environments, including Kubernetes-based container platforms.
Support the operation and sustainment of containerized workloads, including application deployments, configuration management, and platform updates.
Develop and maintain infrastructure as code using Terraform, Ansible, or similar automation technologies.
Support CI/CD pipeline development and maintenance to enable secure, repeatable platform deployments.
Implement and maintain platform security configurations, including identity-aware access, network segmentation, and least-privilege controls.
Assist with onboarding new mission tenants, applications, and shared services onto the enterprise platform.
Monitor platform health, availability, and performance using logging, metrics, alerting, and dashboard technologies.
Provide Tier 3 technical support for escalated incidents involving compute, storage, networking, identity, and container infrastructure.
Troubleshoot complex technical issues across Linux operating systems, DNS, routing, load balancing, firewalls, and identity and access management.
Investigate incidents, document findings, and support root cause analysis and corrective action development.
Resolve technical issues within established service levels and escalate complex problems to senior engineers and platform leadership as appropriate.
Develop and maintain technical documentation, troubleshooting procedures, and operational runbooks.
Support the implementation of corrective actions and automation improvements to reduce recurring incidents.
Collaborate with cybersecurity personnel to maintain security configurations, continuous monitoring activities, and accreditation documentation.
Provide technical guidance to Tier 2 support personnel and contribute to knowledge-sharing activities.
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.

Experience supporting at least one major cloud environment (AWS, Azure, or a government cloud region) and hybrid cloud or on-premises infrastructure.
Working knowledge of infrastructure as code technologies, including Terraform, Ansible, or similar tools.
Working knowledge of CI/CD pipelines and automated deployment processes.
Demonstrated ability to troubleshoot technical issues across Linux systems, networking technologies (DNS, routing, load balancing, and firewalls), and identity and access management layers.
