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 4 or more years of experience (or Master’s degree with 2 or more years of experience) or equivalent experience in lieu of degree.

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.
