Classified Platform Engineer

About the Role

Anduril Industries is seeking a Classified Platform Engineer to serve as the technical lead for our classified software team. This role involves designing and building platform services and user-facing applications for multi-level classified computing, including a virtual desktop and application broker, a policy-enforcing storage gateway, and administrative interfaces for an access control platform. You will own these components end-to-end, from architecture through the DevSecOps pipeline, working with Cybersecurity, Systems Engineering, and Infrastructure Engineering. This is a hands-on role with technical authority, where you will set the architecture, choose patterns, and establish engineering standards. As the team grows, you will lead it technically with a path towards formal technical leadership.

Key Responsibilities

• Act as technical lead for the classified software and platform team: own the architecture of the application portfolio, set standards, and make tradeoff decisions.
• Design and build production web applications in React and Go that operate fully air-gapped inside accredited classified environments.
• Develop and work with S3 storage APIs and policies.
• Build administrative and operator interfaces for the access control platform, and design relational and distributed datastores for authorization decisions, audit records, and application state.
• Own the DevSecOps path to production: containerize and deploy to Kubernetes through GitOps CI/CD pipelines that scan, sign, and produce required accreditation evidence.
• Decompose multi-quarter programs into well-scoped work for other engineers and grow team members through design review, code review, and pairing.
• Partner with Cybersecurity, Program Management, and business line stakeholders to capture requirements and translate them into a technical plan delivered on time and on budget.

Requirements & Tech Stack

• Professional experience building and shipping production web applications with React (or a comparable modern front-end framework) and TypeScript, including interfaces for complex domains where operator workflow matters.
• Professional experience developing backend services in Go.
• Experience designing and working with relational databases such as PostgreSQL or CockroachDB, including schema design, migrations, and query performance.
• Experience with containerization and container orchestration (Podman or Docker, and Kubernetes).
• Experience with GitOps and Continuous Integration / Continuous Delivery (CI/CD) pipelines in an Agile development process.
• Knowledge and experience with Linux Operating Systems (OS) such as Red Hat Enterprise Linux (RHEL), Rocky Linux, or Ubuntu.
• Experience leading technical work: owning system architecture, reviewing designs and code, setting direction for a small team, and communicating clearly in design documents, tradeoff analyses, and decision records.
• Eligible to obtain and maintain a US Top Secret Clearance with customer's approval.
• May be required to obtain and maintain a DoD 8140/8570 qualifying certification.

Qualifications (Desired)

• Experience with virtual desktop infrastructure or application and desktop brokering (e.g., Citrix, Omnissa/VMware Horizon, Leostream, Apache Guacamole, Kasm), and with virtualization orchestrated through Kubernetes such as KubeVirt.
• Experience implementing authorization systems (RBAC, ABAC, or relationship-based models), integrating applications against an external policy decision point, and Policy as Code (PaC) tools such as OPA, Oso, Cedar, or Kyverno.
• Experience with S3-compatible object storage APIs, POSIX filesystem semantics, or FUSE.
• Experience building software for air-gapped or network-isolated environments, including dependency vendoring and offline builds.
• Experience with DevSecOps supply-chain security practices including SBOM generation, artifact signing, and provenance attestation.
• Proficiency with core security concepts including encryption, authentication, identity and access management, and Zero-Trust Architecture (ZTA), plus an understanding of NIST SP 800-53 controls and their technical implementation.
• Experience with observability tooling: structured logging, metrics, and distributed tracing.
• Experience as a tech lead or founding engineer on a product team, including establishing engineering practices, onboarding new engineers, and interviewing/hiring software engineers.
