Senior Network Infrastructure Engineer

******** UPDATE ON THIS ROLE:

The need has shifted a bit to be more storage/hypervisor focused, particularly around Prox Mox, Linux based storage that goes with that, and general data center / enterprise storage background. Our client is currently a VMWare shop, but they intend to move us to Prox Mox in the next year. Storage wise, they have a mix of Cisco UCS/Cloudian/Qumulo products in a three-tiered deployment based on need and retention.

Location:inner SE Portland, OR (Hybrid – ~3 days/week on-site)

Type:2-year contracts (potential for extension)

We’re supporting our client as they add a Senior Network Infrastructure Engineer to their Network & Server team. This role focuses on high-availability, converged network infrastructure in a complex enterprise environment where reliability and safety really matter.

This role can be one of two skill-sets:

• Lead design, deployment, and support of next‑gen firewalls (Palo Alto preferred) in a highly segmented environment.
• Help build out new network modules to isolate services (e.g., separating CCTV from rail environments) and reduce blast radius.
• Serve as a primary/secondary SME for firewall policy, rule sets, and security best practices (PCI/HIPAA exposure is a plus)

• Own design and support of Cisco wireless controllers and Meraki environments across yards, facilities, and vehicles.
• Support existing operations where vehicles use Wi‑Fi and cellular to offload CCTV footage, and help drive the long‑term move toward real‑time cellular connectivity across the fleet.
• Work on projects involving mobile/vehicle RF, MPLS networking, and future cellular‑first architectures.

If you’re stronger on one side (firewalls
or
wireless/Meraki) but have strong route/switch fundamentals and are comfortable learning, our client is open to candidates who can grow into the tools.

In either role, you’ll:

• Plan, design, implement, and manage our client’s IT communication and network infrastructure, with an emphasis on high availability and security.
• Support and improve a complex, converged environment:
  Cisco switches/routers, wireless, firewalls, VPN/remote access, and monitoring/platform tools.
• Troubleshoot network and server issues in a mission‑critical 24/7 environment
  , quickly resolving outages and degraded service in coordination with internal teams and vendors.
• Integrate with Microsoft‑centric platforms:
  Active Directory, M365 hybrid
  , virtualization, backup, and real‑time monitoring systems.
• Participate in, and sometimes lead,
  complex projects
  from design through implementation and cutover.
• Help drive IT process maturity
  , documentation, and cross‑team collaboration as they continue to modernize their infrastructure and practices.
• Some off‑hours / on‑call participation is expected to support critical systems.

• ~4+ years
  of hands‑on experience in
  network management and network security
  in a complex enterprise setting.
• Strong experience designing, implementing, and supporting multi‑site network environments.
• Proven background supporting mission‑critical systems (public sector, utilities, transportation, healthcare, financial services, etc. all translate well).

• Strong routing/switching
  (Cisco) and converged network design.

• Next‑gen firewalls (ideally
  Palo Alto
  , but Fortinet/Check Point/etc. are also relevant).
• Network segmentation, policy design, and rule‑set hygiene.

• Cisco wireless controllers
  and
  Meraki
  wireless management.
• Experience with large‑scale Wi‑Fi deployments and/or vehicle/yard environments is a…
