Why we read it this way (6)
The role title is 'Systems Engineer' but the required skills are heavily software-development oriented (Java, Spring Boot, Puppet, Jenkins, Ansible, full-lifecycle development). It is classified as Computer Systems Analysts (15-1211) given the explicit systems analysis, requirements allocation, and interface definition duties, with Software Developers (15-1252) as a close runner-up.
The experience requirement is stated as a range tied to degree level: BS + 12 years, or Masters + 10 years, or Doctorate. The minimum (10 years with a Masters) is used for the overall years minimum; the degree requirement reflects the lowest qualifying degree (Bachelor's), though the posting does not accept equivalent experience in lieu of a degree.
No work location or CBSA is specified in the posting. The TS/SCI with polygraph clearance requirement strongly implies an on-site position near a cleared facility, but no city or state is stated.
The 'core languages' requirement lists Python, Java, JavaScript, C++, or C# as alternatives. Java is also called out separately as a hard requirement for software development, so it is listed both as the primary in the alternatives group and as a standalone required skill.
The 'Desired Skills' section lists Kubernetes, Docker, Node.js, AWS Lambda, SDKs, and AI — all treated as preferred. 'SDKs' was omitted as it names no specific technology.
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.
