Why we read it this way (8)
The role requires an active Secret clearance at hire, with eligibility to obtain TS/SCI — the TS/SCI is a condition of employment, not a day-one hard gate, but the clearance requirement is set to TopSecretSci to reflect the eligibility requirement.
The offensive toolset requirement names Kali Linux and Cobalt Strike as examples ('such as'); both are listed under the same requirement, so Cobalt Strike is captured as an alternative to Kali Linux rather than a separate skill.
The OSCP/OSWE/CRTO/etc. certification requirement allows up to 1 year post-hire to obtain — it is still a hard gate (must obtain), so it is marked required with all named alternatives captured.
The DoD 8570 IAT Level II certification (Security+, CySA+, CCNA-Security, or CND) is a hard gate; the specific cert options are not broken out individually as they are interchangeable fulfillments of the same requirement.
Total years minimum is set to 3, reflecting the stated 'at least 3 years of experience in computer design, software development or computer networks'; the 1-year penetration testing requirement is captured on the Penetration Testing skill.
The alternative occupation code 15-1252 (Software Developers) is noted because the role explicitly requires rapid tool/script development in multiple programming languages, but the primary day-to-day work is offensive security/red team operations.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Network Protocol Analysis, DoD 8570 IAT Level II, Red Team C2 Infrastructure.
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.
