What You Will Do:

As a Platform Engineer on the defense engineering team you will design, build and run Kubernetes clusters on bare metal from the ground up. You will own the platform end to end: hardware bring-up, cluster lifecycle, day-2 operations, security hardening and accreditation support. You will work closely with our development and product teams to get mission software delivered.

What We Value:

- Bringing up bare-metal hardware from the rack up, including out-of-band management (BMC, IPMI, Redfish) and automated OS provisioning.

- Building and running production Kubernetes on bare metal from scratch, including cluster lifecycle, upgrades, operators, networking, storage and ingress.

- Automating infrastructure as code with Ansible and Terraform/OpenTofu.

- Building CI/CD pipelines (Argo CD, Jenkins, GitLab CI) that deliver software into disconnected environments.

- Running platforms in production, including monitoring, alerting, incident response, capacity planning and runbooks.

- Working with network and security teams to bring external data sources onto the platform, including firewall rules, cross-domain transfers, and data feed connectivity.

- Strong grounding in Linux systems administration, networking and security.

- Hardening and accrediting systems to NIST and RMF standards in restricted, disconnected or classified environments.

- Explaining technical and mission concepts clearly to partners and customers.

- Working well with operations and development teams in different locations.

Requirements:

- An active TS/SCI clearance.

- A bachelor’s degree and 5+ years in platform engineering, DevOps, systems administration, infrastructure or a related field.

- A DoD 8140 Cyber Workforce certification for privileged users (such as Security+ CE).

- Willing to work onsite in Virginia 50% of the time and to provide on-call support during designated surge events.
