- Description Lead Dev Sec Ops  Platform Engineer Leidos is seeking Lead Dev Sec Ops  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 Lead Dev Sec Ops  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, Git Lab 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. Primary Responsibilities
* Own the implementation and operation of software delivery pipelines, from build through production release

* Develop, administer, and maintain automated build, test, deployment, and release workflows using Git Lab CI/CD, Git Lab Runners, AWS Code Pipeline, AWS Code Build, and related automation technologies.

* Administer Git Lab platform infrastructure (projects, groups, runners, repositories, and permissions), and develop reusable CI/CD templates and pipeline libraries adopted across Agile teams.

* Integrate automated security capabilities into software delivery pipelines, including static application security testing (SAST), software composition analysis (SCA), container image scanning, secrets detection, Infrastructure-as-Code scanning, and software supply chain security.

* Design and maintain automated deployment strategies for Kubernetes-based applications utilizing Helm, Git Ops methodologies, and progressive deployment techniques.

* Configure and administer Git Lab Container Registry, package repositories, artifact repositories, and software dependency management solutions supporting secure software delivery.

* Collaborate with Cloud Systems Owners to ensure cloud platforms effectively support automated software deployment, scalability, operational monitoring, and application reliability.

* Partner with software development teams to improve build reliability, deployment consistency, release quality, and developer productivity through automation and self-service engineering capabilities.

* Work closely with cybersecurity teams to integrate security throughout the software development lifecycle and ensure compliance with organizational security requirements.

* Troubleshoot build failures, deployment issues, pipeline performance, dependency management, and software delivery problems across development, integration, and production environments.

* Develop and maintain pipeline documentation, deployment procedures, release management processes, operational guidance, and engineering standards.

* Participate in Agile ceremonies while supporting multiple software development teams through automation,…
