- Strong PowerShell scripting/automation skills; experience with infrastructure‑as‑code tools and/or configuration management (or demonstrated willingness to adopt and lead these efforts).
- Willingness to participate in an on‑call rotation and lead through high‑severity incidents.
- Meticulous attention to procedure, change management, and meeting service expectations.
Nice to Haves
