4680 – Senior Network Infrastructure Engineer

Senior Network Infrastructure Engineer (2 Openings)

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 two Senior Network Infrastructure Engineers to their Network & Server team. These roles focus on high-availability, converged network infrastructure in a complex enterprise environment where reliability and safety really matter.

 

We’re recruiting for two senior-level roles:

Sr. Network Engineer – Firewall / Security Focus

– 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)

 

Sr. Network Engineer – Wireless / Mobility (Cisco / Meraki) Focus

– 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 both roles, 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.

 

Core background (senior-level):

– ~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).

 

Technical strengths we’re targeting (mix across both roles):

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

– Firewall / Security role:

Next-gen firewalls (ideally Palo Alto, but Fortinet/Check Point/etc. are also relevant).

Network segmentation, policy design, and rule-set hygiene.

– Wireless / Mobility role:

Cisco wireless controllers and Meraki wireless management.

– Experience with large-scale Wi-Fi deployments and/or vehicle/yard environments is a plus.

– Exposure to MPLS, mobile/vehicle RF networking, CCTV, and voice/telephony is helpful.

-Experience with cloud/hybrid (Azure and/or AWS) is a nice-to-have.

-Relevant certifications (CCNA/CCNP, Network+, Security+, Microsoft, etc.) are appreciated but not required.

 

Soft Skills & Culture Fit

Our client is very focused on collaboration and communication as they raise IT maturity across the organization. They’re looking for someone who:

– Communicates clearly with both technical and non-technical stakeholders.

– Can translate technical tradeoffs into business language and help shape requirements.

– Works well across teams instead of in silos.

– Is curious, adaptable, and willing to learn new tools (e.g., Palo Alto, Meraki) as long as the core fundamentals are solid.

-Cares about public service, safety, and reliability for the community.
