This role requires candidates who are currently authorized to work in the U.S. without sponsorship, and C2C arrangements are not accepted. This role is hybrid in Torrance, CA.

Please submit your resume and send to  if you are interested. Thank you!

We are looking for a hands‑on Network & Systems Administrator to join a lean IT team supporting a fast‑paced, distributed environment spanning dozens of locations nationwide. This is not a pure security role, and it is not a pure networking role — it is an infrastructure generalist with deep identity and access management ownership and a security‑first mindset.

The ideal candidate evaluates every infrastructure decision through the lens of security impact. If that is how you naturally think, this role is built for you.

• Over 500 users across the organization
• Several thousand managed endpoints
• Dozens of physical locations nationwide
• Hybrid cloud infrastructure (on‑premises + Azure)
• Lean, collaborative IT team

• 30% — AD / Cyber / Security & IAM
• 20% — Networking Support

• Manage and optimize Azure infrastructure including IaaS, hybrid identity, and cloud services
• Drive Azure cost optimization, resource governance, and performance tuning
• Maintain infrastructure health across a distributed, multi‑site environment

• Active Directory administration (critical requirement)
• Group Policy design, management, and enforcement
• Lead Identity and Access Management (IAM) maturity initiatives
• Manage Azure AD / Entra  hybrid identity configurations
• Identity lifecycle management: provisioning, de‑provisioning, and role‑based access
• Endpoint security deployment and monitoring (AV / EDR)
• Evaluate all infrastructure changes for security posture impact

• Understand and work within existing firewall policies
• Configure network ports and support switching as needed
• Handle physical infrastructure support and on‑site troubleshooting across facilities
• Support remote sites as needed

• Experience supporting multi‑site organizations with 20+ locations strongly preferred
• Strong Active Directory and IAM background — required
• Hands‑on experience rolling out SSO across multiple enterprise applications
• Azure administration experience with a focus on optimization and hybrid identity
• Familiarity with endpoint security platforms (EDR, AV, device management)
• Ability to own projects independently within a lean IT team
• Background in environments with 500+ users, thousands of endpoints, and hybrid cloud infrastructure

• 2–3 trips per year to support remote locations

• Not a dedicated security engineer position
• Not a pure network / firewall architect role
• Not a helpdesk or tier‑1 support position

• SSO successfully rolled out across core enterprise applications
• Identity and access processes tightened, documented, and enforced
• Clear visibility into endpoint security posture
• Azure infrastructure optimized for performance and cost
• Reduced access sprawl and stronger policy enforcement across the environment
