Location: Santa Clara, CA
Position Type: Contract
Description: This role focused on delivering a successful installation and configuration of a new enterprise application. As the Senior Systems Administrator, you’ll lead environment readiness and cutover activities across servers, networks, identity, and security. You’ll own the Cisco stack (switching/routing/wireless, ASA/Firepower or Meraki, AnyConnect VPN, ISE/NAC) needed to support the application—planning and implementing network segmentation, firewall/NAT rules, VPN access, load balancing, QoS, and certificate/PKI requirements.
In parallel, you’ll architect and administer Duo for MFA/SSO at scale, including SAML/RADIUS integrations with the application, conditional access policies, device trust, enrollment workflows, and user lifecycle.
Responsibilities include building and hardening Windows/Linux hosts, integrating with AD/Entra ID and DNS/DHCP, establishing monitoring/logging, documenting configs/runbooks, and coordinating change management with vendors and internal teams.
Required Skills:
· The ideal consultant has 7+ years in systems/network administration (3+ in a senior capacity) with deep, hands-on expertise in Cisco networking/security and Duo administration supporting production application deployments.
· You’re comfortable executing on an aggressive timeline: scoping and sequencing tasks, troubleshooting complex issues, and driving cutover/rollback plans with minimal downtime.
· Required strengths include automation/scripting (PowerShell; Bash/Python a plus), secure cloud/network patterns (Azure/AWS connectivity, conditional access), endpoint/MDM familiarity (e.g., Intune), and experience in regulated environments (SOC 2, HIPAA, or CJIS).
· Excellent communication and stakeholder management are essential, along with crisp documentation and knowledge transfer to client staff at project close.
Preferred certifications:
· Cisco CCNP (or higher), Duo Certified Administrator, Microsoft AZ-104/SC-300, and/or Security+.
