Sr. Systems and Network Engineer

Invent the future with us.

Ampere is a semiconductor design company for a new era, leading the future of computing with an innovative approach to CPU design focused on high‑performance, energy efficient AI compute.

As a pioneer in the new frontier of energy efficient high‑performance computing, Ampere is part of the Softbank Group of companies driving sustainable computing for AI, Cloud, and edge applications. Join us at Ampere and work alongside a passionate and growing team.

Join a friendly, cooperative environment supporting a global workforce. We are expanding our secure access capabilities by building out Cisco ISE (NAC) and strengthening our end‑to‑end infrastructure across systems, security, and network connectivity.

As a Senior Systems & Network Engineer, you will lead and troubleshoot complex, cross‑domain issues—often with minimal supervision—while delivering secure, reliable environments. You’ll help us deploy and improve our VMware‑based infrastructure, Linux/Windows security hardening, SD‑WAN connectivity, and network access controls (NAC), and help build out a new data center.

• Participate in/lead new technology rollouts and infrastructure upgrades.
• Support and troubleshoot global VMware environments.
• Ensure systems and network devices are configured securely and reliably for production operations.

• Implement security hardening and best practices for primarily Linux systems.
• Support vulnerability remediation workflows, patch coordination, and access control alignment.
• Use policy‑driven configuration approaches and maintain baseline documentation.

• Help in maintaining and troubleshooting SD‑WAN solutions and site‑to‑site connectivity.
• Preferred: exposure to AT&T, Lumen, or Cato SD‑WAN (or similar service provider SD‑WAN offerings).
• Analyze connectivity/performance issues and drive corrective actions across network and security layers.

• Support and expand Cisco ISE deployments for posture/authentication and network authorization.
• Any prior NAC experience is valuable (e.g., Packet Fence, ISE, or equivalent NAC technologies).
• Assist with:
• device profiling and posture‑based access decisions
• segmentation/VLAN assignment (as applicable)
• troubleshooting authentication failures and policy edge cases
• integrations needed for NAC (directory services, RADIUS, syslog/telemetry, etc.)

• Own complex incidents end‑to‑end and drive RCA (root cause analysis).
• Document technical findings, runbooks, and changes.
• Write and maintain policies (security and operational), ensuring they’re practical, testable, and followed.

• Bachelor’s degree in an IT‑related discipline or equivalent with 5 years minimum relevant experience; or Master’s degree in an IT related discipline or equivalent with minimum 3 years experience.
• Senior‑level, hands‑on experience in systems and networking.
• Senior‑level working experience with VMware.
• Demonstrated security expertise in Linux and Windows environments (e.g., hardening, access control, secure configuration).
• Experience supporting/troubleshooting SD‑WAN (vendor‑agnostic acceptable).
• Experience with NAC technologies (Cisco ISE preferred; Packet Fence or other NAC experience acceptable).
• Experience with data center builds or equivalent infrastructure provisioning projects.
• Proven ability to work independently, take ownership, and resolve issues effectively.
• Strong troubleshooting skills across network + systems + security.
• Ability to write clear policies and documentation (runbooks, standards, configuration guidance).
• Familiarity with network segmentation concepts (e.g., VLAN/VRF) and access control models.
• Scripting/automation skills (e.g., Power Shell, Python, or Bash) to support troubleshooting and policy consistency.
• Experience implementing or integrating Cisco ISE (or comparable NAC platforms), with familiarity acceptable if not already deep.
• Scripting/automation and/or prior experience that demonstrates consistent policy enforcement and operational readiness.

• VMware (e.g., VCP…
