Platform Engineer - Defense

About ASI

ASI is the frontier AI company that dynamically orchestrates critical infrastructure and defense assets, across air traffic control, energy, logistics, and combat operations. ASI's systems simulate physical operations, hours, days, and weeks ahead, so the people running air traffic control, the electric grid, and military operations can catch problems early and act before they spread. ASI is powering vital infrastructure for customers like United Airlines, National Grid, the Federal Aviation Administration, Delta Air Lines and the Department of War. ASI is headquartered in Boston with offices in Washington, DC, Denver, and Europe, and is backed by leading investors, including Andreessen Horowitz, Citadel Securities, and Spark Capital.

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.
