Network & Systems Administrator - Infrastructure / IAM / Security
New Today
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.
About the Role
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.
Environment
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
Role Breakdown
50% - Server & Cloud Infrastructure (Azure optimization focus)
30% - AD / Cyber / Security & IAM
20% - Networking Support
Core Responsibilities
Server & Cloud Infrastructure
Manage and optimize Azure infrastructure including IaaS, hybrid identity, and cloud services
Administer on-premises server environments across multiple data centers
Drive Azure cost optimization, resource governance, and performance tuning
Maintain infrastructure health across a distributed, multi-site environment
Security & IAM
Active Directory administration (critical requirement)
Group Policy design, management, and enforcement
Lead Identity and Access Management (IAM) maturity initiatives
Drive SSO rollout across enterprise applications

Endpoint security deployment and monitoring (AV / EDR)
Evaluate all infrastructure changes for security posture impact
Networking Support
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
What We Are Looking For
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
Travel
2-3 trips per year to support remote locations
What This Role Is Not
Not a dedicated security engineer position
Not a pure network / firewall architect role
Not a helpdesk or tier-1 support position
What Success Looks Like
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
