What this job asks for AI summary
A software engineering role supporting Electrical Ground Support Equipment (EGSE) on a long-running naval ballistic missile program. Day-to-day work involves modernizing test equipment software for improved efficiency, security, automation, and scalability, collaborating with software, systems, electrical, and test engineers in an Agile environment. Suits candidates with hands-on programming experience (C/C#/C++, LabView, Python, or TestStand) and hardware/software integration background who can obtain a Top Secret clearance.

Why we read it this way (7)
The role sits at the boundary between software development (15-1252) and test engineering (15-1253): the primary work is developing and modernizing Electrical Ground Support Equipment (EGSE) software, but test equipment integration and validation are central duties. 15-1252 was chosen as the primary code because the JD emphasizes software engineering, modernization, and development lifecycle over pure QA/testing.
The programming language requirement lists C, C#, C++, LabVIEW, Python, and TestStand as a single 'one or more of the following' gate. C/C#/C++ are captured as alternatives of each other under one skill; LabVIEW, Python, and TestStand are each emitted separately since they are distinct tools — a candidate need only hold one of the group to satisfy the gate, but each is a named technology in its own right.
The JD states 'Secret Clearance needed to start with the ability to obtain and maintain a Top Secret clearance.' The clearance gate is set to Top Secret per the explicit Clearance Level field and the requirement to obtain/maintain TS.
A Bachelor's degree in Engineering is listed under Desired Skills (not Basic Qualifications) and explicitly allows 'equivalent experience/combined education,' so the degree requirement is set to None.
The salary range quoted ($93,200–$164,450) is explicitly for Colorado (among other states) and is the range applicable to the Littleton, CO work location.
The 3+ years of experience requirement is stated in the role description section ('Key activities') and repeated implicitly by the 'Experienced Professional' experience level label; it is treated as the overall role-level minimum.
Requires a Top Secret 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.
