Validation Engineer Jobs in Frederick, MD (NOW HIRING)

Leidos is seeking Senior 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.

Please note, this exciting position is currently unfunded and is in anticipation of future work.

In this position, you will serve as a Senior DevSecOps Platform Engineer, providing technical leadership for the design, implementation, and continuous evolution of secure software delivery platforms supporting multiple Agile development teams.
