  • Collaborate with product owners, architects, and engineers in an Agile/SAFe environment

  • Participate in sprint planning, daily standups, reviews, and retrospectives

  • Collaborate with systems engineering and program teams to translate requirements into working software solutions

  • Develop clean, maintainable, and testable code following CI/CD and DevSecOps practices

  • Contribute to system design discussions and technical decision-making

  • Integrate services with databases, messaging systems, and external APIs

  • Support troubleshooting, performance tuning, and continuous improvement

  • Familiarity with Scaled Agile Framework (SAFe)

  • Experience working with relational and/or NoSQL databases

  • Hands-on experience with Kafka or other event-streaming technologies

  • Cloud experience (AWS, Azure, or GCP)

  • Desired but not required: Commutable distance to Gaithersburg, MD 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.
