What this job asks for AI summary
A senior-level DevOps role supporting mission-critical, classified government applications built on AWS. Day-to-day work centers on managing cloud infrastructure across the full environment lifecycle, maintaining CI/CD pipelines, overseeing containerized workloads, and operating monitoring and logging systems. The position also involves incident analysis, root-cause reporting, and providing technical guidance to less experienced engineers. A TS/SCI clearance with polygraph is required.

Why we read it this way (9)
The role title is 'DevOps Engineer Principal' — GDIT uses 'Principal' as a seniority label in their internal leveling, but the actual scope (owning a portfolio of applications for a secure customer, providing technical guidance to less-experienced engineers) aligns with a Senior individual-contributor band rather than a true org-wide Principal. Seniority is assessed as Senior accordingly.
The role sits between Software Developers (15-1252) and Network/Systems Administrators (15-1244): it involves building and maintaining cloud infrastructure with IaC (Terraform, CloudFormation) and CI/CD pipelines, which leans toward 15-1252, but also has a strong operations/monitoring flavor. 15-1252 was chosen as primary given the emphasis on architecting, building, and coding (Python/Java, Lambda, Serverless Framework, CodeBuild/CodeDeploy).
A TS/SCI with Polygraph is explicitly required — this is a hard gate.
Python and Java are listed together as 'preferred' within the required skills block ('Python, Java preferred'), so they are treated as preferred rather than hard gates.
Aurora, MariaDB, and MySQL appear in a narrative 'experience with databases' sentence rather than the bulleted required-skills list; treated as preferred. Aurora is listed as the primary with MariaDB and MySQL as alternatives since all three are interchangeable relational database options in this context.
Splunk appears only in a narrative/context sentence ('ie. Cloudwatch, Splunk') rather than the required-skills bullet list; treated as preferred.
The AWS Certified DevOps Engineer certification is called out in the job family metadata and body text. Certifications are not emitted as skills per extraction rules, but hiring managers should note this is listed as a requirement.
The salary range of $157,250–$212,750 is described as a 'likely' range, not a guarantee.
Requires a TS/SCI clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
