Why we read it this way (11)
The role is listed as 'DevOps Engineer' with no explicit seniority level in the title; however, the Basic Qualifications require a Bachelor's degree plus 5 years of combined Linux/scripting/configuration management experience, which maps to a Mid-level band. The scope is team-member delivery rather than cross-team technical leadership, so Senior was not warranted despite the 5-year floor.
TS/SCI with Polygraph is explicitly required ('TS/SCI with Poly' stated in the posting header). This is a hard gate.
Primary location is Herndon, VA (Washington DC metro); Denver, CO is listed as an optional alternative location. The DC metro CBSA is used as the primary.
The degree requirement is a Bachelor's in Computer Science or AIS — stated as required with no 'or equivalent experience' escape clause, so it is treated as a hard gate.
GitLab CI is listed alongside Git/SVN/CVS/GitLab as revision control experience; it is the only CI-specific tool named and is captured separately from the general Git/version-control skill.
Bash, Korn, and Bourne shells are listed together as a single scripting requirement; Bash is used as the canonical name with Korn and Bourne as alternatives.
Lustre and NFS are listed together under Desired Skills as filesystem experience; Lustre is the primary name with NFS as an alternative since they serve the same file-system role in HPC contexts.
InfiniBand and OmniPath (Omni-Path) are listed as interchangeable high-speed fabric options under Desired Skills.
RDMA communications experience (InfiniBand/OmniPath) and Ethernet networking are listed under Desired Skills and are marked preferred accordingly.
Security+ certification is listed under Basic Qualifications and is treated as a hard gate.
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.
