About The Position

Leidos is seeking Lead DevSecOps Platform Engineers to join the Air Traffic Business Area within the Homeland Sector, supporting the development of next-generation flight service and air traffic systems. This work aligns with the FAA's broader initiative to modernize legacy flight service capabilities, replacing aging infrastructure with scalable, cloud-based platforms designed to improve safety and operational efficiency—particularly in remote and high-dependency aviation environments. These efforts focus on delivering mission-critical, future-ready solutions that provide safety-critical flight services to the pilot community. In this position, you will serve as a Lead DevSecOps Platform Engineer supporting Agile software development teams through the design, implementation, and continuous improvement of secure software delivery platforms and automated development pipelines. You will be responsible for enabling automated build, test, security scanning, deployment, and release processes while integrating security throughout the software development lifecycle. This role is primarily responsible for the software delivery platform, GitLab administration, CI/CD pipelines, deployment automation, and developer enablement. Cloud infrastructure, Kubernetes platform administration, and cloud operations are performed in close partnership with the Cloud Systems Owner team. Working closely with software engineers, Cloud Systems Owners, systems engineers, cybersecurity personnel, Product Owners, and solution architects, you will help ensure software can be developed, validated, and deployed rapidly while meeting the operational, security, and compliance requirements of mission-critical FAA applications. This position supports government programs and requires the ability to obtain and maintain a favorable Public Trust investigation.
