• Collaborate with development teams to improve build times, deployment frequency, and reliability 

• Support incident response and troubleshooting of infrastructure and deployment issues 

• Implement software supply chain security controls including SBOM generation, artifact signing, and dependency vulnerability scanning 

• Manage artifact repositories and build provenance ensuring integrity of software deliverables throughout the pipeline 

• Support developer platform capabilities including self-service environment provisioning, documentation, and developer experience improvements 

• Embrace an AI-first engineering culture by actively adopting AI-assisted development tools, automation, and modern engineering practices that improve productivity, code quality, and delivery velocity. 

Core Technical Qualifications: 

• Bachelor’s degree in Computer Science, Information Technology, or related discipline with 8 or more years of experience (or Master’s degree with 6 or more years of experience) or equivalent experience in lieu of degree.  

• Expert at building and maintaining CI/CD pipelines (Jenkins, GitLab CI, or GitHub Actions) 

• Hands-on experience with Kubernetes cluster management and container orchestration 

• Proficiency with Terraform or equivalent infrastructure-as-code tools 

• Strong experience with Docker and containerization technologies 

• Solid Linux systems administration skills 

• Proficiency in scripting languages (Bash, Python) for automation 

• Experience with security scanning tools and DevSecOps practices 

• Understanding of networking, load balancing, and service mesh concepts 

• Familiarity with Agile/SAFe delivery and DevOps culture 
• Experience with software supply chain security tools (Sigstore, SLSA, SBOM generation) 
• Knowledge of artifact management systems and build provenance tracking 
• Experience supporting internal developer platforms and developer experience initiatives 

• Ability to obtain and maintain a Public Trust
• U.S. citizenship required
• Successful completion of background investigations as required by the government customer

Preferred / Desired Qualifications 

• Experience with cloud platforms (AWS, Azure) including GovCloud environments

• Desired but not required: Commutable distance (1 hour or less) to Gaithersburg, MD; Eagan, MN; or Egg Harbor Township, NJ.

Why Leidos?

You’ll work on systems where performance, precision, and reliability matter — every second. This is not experimental AI for prototypes. This is disciplined, responsible AI applied to mission-critical software that supports national infrastructure.

If you’re excited by solving complex problems in regulated, real-world environments — and using AI as a force multiplier rather than a shortcut — we’d like to talk.
