Principal DevSecOps / Platform Engineer

• Work across a broad portfolio rather than a single narrow program - variety and exposure to cutting-edge problems in government software delivery
• Significant investment in AI, automation, and modern platform engineering - not legacy maintenance
• Small, senior team where individual contributions have outsized impact
• Opportunity to shape how the our customers’ missions are built and delivered using secure software at scale
• Exposure to Growth activities (proposals, customer engagements) for engineers who want to develop business acumen alongside technical depth

KEY RESPONSIBILITIES

DevSecOps Engineering - Primary Focus

Utilize AI-assisted Development tools and frameworks to:

• Design, develop, and maintain CI/CD pipelines for build, test, security scanning, and release across unclassified and classified environments
• Integrate and operate security scanning toolchains (SAST, SCA, container scanning, SBOM generation) as automated pipeline stages
• Use AI-assisted development workflows daily - code generation, automated testing, intelligent code review, and documentation - and champion their adoption across teams
• Contribute to the development of agentic AI capabilities including tool orchestration, prompt engineering, and workflow automation
• Build tooling and automation to support continuous Authority to Operate (cATO) processes, including automated evidence collection, compliance reporting, and policy enforcement
• Develop and maintain hardening pipeline templates that product teams consume for secure-by-default software delivery
• Support platform’s security pipeline layer - build, test, and release process for software packages that include both application code and runtime platform components
• Implement and enforce software supply chain security controls (signing, provenance, artifact integrity)
• Troubleshoot build and deployment failures, support development teams consuming shared pipeline services

Platform Engineering

• Deploy and operate Kubernetes clusters (Big Bang / Iron Bank baseline) in classified (CUI/IL5) environments
• Deploy, configure, and support AI-powered development tools (GitLab Duo, LLM-based code assistants, agentic AI frameworks) for platform consumers and internal team use
• Support AI/ML platform infrastructure (model serving, GPU workloads, data pipelines) as part of the broader platform offering
• Stand up and maintain shared platform services: Harbor (container registry), Nexus (artifact repository), Vault (secrets management), ArgoCD (GitOps deployment)
• Implement Infrastructure-as-Code for environment provisioning, cluster lifecycle, and configuration management (Terraform, Ansible)
• Support multi-cluster management and hub/spoke deployment models - build in shared services, deploy into downstream accounts
• Configure and troubleshoot network connectivity, Zscaler integration, and Okta/SAML identity federation for platform consumers
• Contribute to platform evolution including self-service namespaces, developer onboarding, and golden-path templates
• Maintain and improve multiple production software factory environments serving diverse federal customers
• Contribute to runbooks, operational documentation, and incident response procedures
