Why we read it this way (8)
Location is not stated in the posting; CBSA/state fields are left blank. The company (WOONGJIN, Inc.) appears to be US-based but no city or state is specified.
The posting explicitly prohibits C2C (corp-to-corp) arrangements, suggesting a direct W2 hire, consistent with full-time employment.
CompTIA Security+ (or equivalent DoD 8570.1 IAT Level II certification) is stated as 'required' in the qualifications section and is treated as a hard gate. No security clearance itself is required — only the certification.
Linux certifications (CompTIA Linux+, RHCSA, RHCE) are listed as 'preferred,' so they are not treated as hard gates.
Cisco network equipment management is listed as 'preferred' in the qualifications, but network equipment management broadly is listed as a core job duty; Cisco is captured as a must-have skill with Mellanox as an alternative, reflecting the operational scope of the role.
VMware is called out with 'especially high skill level' in the qualifications section and is treated as a hard gate. KVM is listed alongside it in the job duties as an alternative virtualization platform.
Storage platforms (NetApp, Dell/EMC, PureStorage) appear in the job duties narrative rather than a formal requirements section and are marked as preferred.
Tools such as Jira, LDAP, Foreman, GLPI, FlexLM, Apache, and Windows Server appear in the duties/operational context rather than the qualifications section and are marked as preferred.
