Senior DevSecOps Engineer

Help power the cloud-based data platforms that enable Intelligence Community analysts and data scientists around the world to turn complex information into actionable intelligence supporting critical national security missions.

Leidos is seeking an innovative, mission-driven Senior DevSecOps Engineer to support the Chinook Program serving our Intelligence Community (IC) customer. In this role, you'll help ensure that more than 400 analysts, engineers, and data scientists worldwide have reliable, secure access to the cloud-based tools and computing resources they depend on to process data, develop analytical solutions, and support mission-critical decisions.

This is an exciting opportunity to combine your Bash or Python scripting expertise with cloud platform administration, automation, and DevSecOps engineering. You'll support multiple Amazon Web Services (AWS) Virtual Private Cloud (VPC) environments hosting Databricks and/or Syntasa platforms, helping configure and maintain user access, compute resources, clusters, and critical cloud infrastructure. Your contributions will directly improve platform reliability, streamline administrative operations, strengthen security, and accelerate the delivery of data-driven capabilities to mission users.

You don't need to be a Databricks or Syntasa expert on day one. We're looking for an adaptable, technically curious engineer with strong scripting skills, experience administering commercial off-the-shelf (COTS) applications, and a passion for solving complex challenges. You'll receive hands-on, on-the-job training (OJT) to develop specialized expertise in these platforms while contributing to meaningful engineering and automation initiatives.

If you thrive on solving technical challenges, enjoy automating repetitive tasks, and want your engineering expertise to support intelligence professionals across the globe, this is your opportunity to make an impact where it matters most.
