About The Position

We’re hiring across IT and Security Systems Administration Levels 1–3 (final level determined by experience). You will provide hands‑on Windows, Linux, and MacOS administration across on‑prem and cloud environments, deliver reliable desktop support to a high‑speed engineering org, and partner with IT & Security Engineering on larger‑scale, critical projects and hardening efforts. Experience working in or supporting data centers is valued; No formal on‑call rotation exists today; a rotation may be introduced in the future.

Requirements

Hands‑on Windows administration across on‑prem (AD/GPO) and cloud (Entra ID, Intune, Microsoft 365).
Demonstrated desktop support experience (L2/L3), strong troubleshooting, and clear documentation.
Security‑minded approach: least‑privilege, patch discipline, vulnerability remediation, and incident handling fundamentals.
Automation with PowerShell or Python or similar (modules, remoting, error handling) to turn manual tasks into reliable scripts.
Experience in or exposure to data center environments.

Nice To Haves

Background in nuclear, aerospace, or other highly regulated/critical systems environments.
Familiarity with endpoint protection/EDR, SIEM, and enterprise patch/orchestration tools (e.g., Autopilot/Autopatch, WSUS, MECM/SCCM or equivalents).
Virtualization (VMware or Hyper‑V or ProxMox), basic networking (VLANs, firewalls, VPNs), and PKI/certificates.
Infrastructure‑as‑code or config management (PowerShell DSC, Git; Terraform optional) and DR/backup practices.
If/when datacenter work is required: ability to maneuver equipment safely and follow DC procedures and protocols.

Responsibilities

Windows & identity administration (on‑prem + cloud)
Administer Active Directory/Group Policy, DNS/DHCP, and Microsoft 365/Entra ID; manage Intune/Endpoint Manager policies and device compliance for critical systems.
Own server/endpoint baseline configuration, access controls, and environment hygiene in a critical systems context.
Desktop support & reliability
Provide L2/L3 support, imaging, break/fix, VIP support, and escalations with clear comms and high customer satisfaction.
Maintain patch/update posture for OS and core applications; drive vulnerability remediation in coordination with Security.
Security collaboration
Apply least‑privilege/RBAC, hardening baselines (e.g., CIS), secure configuration, and change control appropriate to regulated environments with guidance from Engineering.
Operate endpoint protection/EDR and contribute data sources to SIEM in partnership with Security Engineering.
Automation & scale
Use PowerShell (and optionally Python) to automate builds, configuration, and repetitive workflows; emphasize configuration‑as‑code and documentation. This is a strong plus.
Data center & Infrastructure support
Periodic racking/stacking, cabling standards, and out‑of‑band management (IPMI/iDRAC/iLO) as needed; asset lifecycle and inventory accuracy.
