• Design, implement, and maintain CI/CD pipelines that support repeatable, secure builds and deployments across environments.
• Provision and manage the GovCloud/IL5 hosting environment, ensuring it meets program security and compliance expectations.
• Implement infrastructure as code (IaC) for cloud resources, cluster provisioning, network/security configuration, and environment replication.
• Deploy and operate Kubernetes platforms for application and data services, including cluster configuration, upgrades, and workload reliability.
• Establish platform observability (logging, metrics, tracing) and operational readiness (runbooks, alerting, incident response support).
• Partner with security and architecture teams to implement platform security controls (least privilege, secrets management, network segmentation, patching cadence).
• Drive reliability engineering practices: backup/restore, disaster recovery planning, performance testing support, and capacity planning.

What you should have

• Clearance: Must maintain a Top Secret security clearance
• Active Security+ Certificate
• Ability to obtain AWS Certificate (Cloud Practitioner, Solutions Architect: Associate/Professional) within one month after onboarding.
• Bachelor's Degree and 5 to 8 years of experience; Master's Degree and 3 to 6 years of experience
• 5+ years of DevOps / platform engineering experience delivering and operating systems in a government cloud environment.
• Strong experience with event streaming architecture and operations (Kafka or equivalent), including production support and performance tuning.
• Demonstrated experience with infrastructure as code (Pulumi, Terraform and/or Ansible) and disciplined configuration management.
• Hands-on experience in AWS GovCloud or Azure Government environments
• Strong Kubernetes experience (deployments, Helm or equivalent packaging, cluster operations, and troubleshooting workload).
• Experience implementing DoD security controls and remediations (hardening and patching OS)
• Experience working in compliance-driven environments (e.g., IL5, RMF-aligned controls) with a security-first operations mindset.
• IC/DoD experience

Tools & Technical Environment

• Kafka (or equivalent event streaming platform)
• Pulumi / Terraform / Ansible (IaC and configuration management)
• Kubernetes
• AWS GovCloud or Azure Government
• ECS (with EC2 or Fargate)

What we'd like you to have

• Operational ownership: builds platforms that are supportable, observable, and resilient.
