Full Job Description

Your Impact

Own your opportunity to support our nation's defense. Make an impact by connecting and securing critical operations across the globe, keeping our country safe and secure.

Job Description

Principal DevSecOps / Platform Engineer

We are seeking a developer-focused DevSecOps engineer to join a high-performing team building and operating software factories, security automation platforms, and AI-enabled development environments for Department of Defense and Federal customers. This role emphasizes hands-on software development within a DevSecOps context - you will write production code, build tooling, and develop applications, not just configure pipelines.

The team supports multiple concurrent internal R&D efforts and customer delivery engagements across defense and federal programs. You will contribute to a range of workstreams including agentic AI application development, software factory platform enhancements, security and compliance automation, and secure software delivery for classified environments.

MEANINGFUL WORK AND PERSONAL IMPACT

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

WHAT YOU’LL NEED TO SUCCEED - REQUIRED SKILLS
Bring your engineering expertise along with a drive for innovation to GDIT. The DevOps Engineer Principal must have:

Education: Bachelor's degree and 8+ years experience. In lieu of degree 12+ years of hands-on experience
Experience: 5+ years of related experience in Software Engineering, DevOps / DevSecOps technologies; 3+ years of hands on experience with Kubernetes

Experience using AI-powered development tools (code assistants, LLM-based tooling, AI-augmented workflows) in daily engineering work — and enthusiasm for pushing their adoption forward
Hands-on experience with CI/CD pipeline development — GitLab CI strongly preferred; Jenkins, GitHub Actions, or similar accepted
Experience integrating security scanning tools into automated pipelines (SAST, DAST, SCA, container image scanning)
Proficiency with Infrastructure as Code (Terraform and/or Ansible)
Experience with containerization (Docker, Helm, OCI artifacts) and container registry management
Strong Linux systems skills — administration, shell scripting, troubleshooting
Solid understanding of Git-based workflows, branching strategies, and GitOps deployment patterns
Experience working in or deploying to classified or air-gapped environments
Ability to work across multiple concurrent projects with shifting priorities
Strong written and verbal communication skills
Security clearance level: Secret Clearance required to start
Location: Remote with travel up to 10%
Citizenship: US Citizenship

PREFERRED QUALIFICATIONS

Experience with Platform One / Big Bang, Iron Bank baselines, or DoD-hardened Kubernetes distributions
Familiarity with DoD security and authorization frameworks (NIST 800-53, RMF, cATO, software factory authorization patterns)
Knowledge of software supply chain security practices — artifact signing, attestation, and SBOM generation (e.g., Sigstore/Cosign, Syft, in-toto)
Experience deploying or operating AI/ML infrastructure or AI development platforms in enterprise or air-gapped environments (model serving, GPU scheduling on K8s, enterprise code-assistant rollout)
Experience supporting growth activities — contributing to proposals, RFI responses, or technical briefings, and engaging customers as a technical SME

GDIT IS YOUR PLACE
At GDIT, the mission is our purpose, and our people are at the center of everything we do.

Growth: AI-powered career tool that identifies career steps and learning opportunities
Support: An internal mobility team focused on helping you achieve your career goals
