Why we read it this way (7)
SOC classification is a genuine judgment call: the role primarily operates and troubleshoots existing infrastructure (Linux, GPU, networking, VMs) rather than building new software, pointing to 15-1244. However, it also involves writing Python/Bash diagnostic tooling and automation, which edges toward 15-1252. 15-1244 was chosen because the dominant day-to-day work is infrastructure operations and escalation support, not shipping software.
No overall years-of-experience floor is stated in the posting; seniority was assessed from scope (independent ticket ownership, escalation handling, runbook authorship) as mid-level.
The schedule options (Mon–Fri fully on-site, or Sun–Thu with one WFH day) mean this is effectively an on-site role; remote is set to false.
TensorFlow and PyTorch appear in both the responsibilities narrative (assisting clients) and the Nice-to-Haves section; they are listed as preferred.
Prometheus and Grafana appear only under Nice-to-Haves.
Firewall rules are listed as a required networking fundamental but are a concept rather than a named tool, so they are not emitted as a discrete skill.
RHCSA and CompTIA Linux+ certifications appear only under Nice-to-Haves and are certifications rather than named technologies, so they are not emitted as skills.
