Job Title: Senior / Core Network Engineer
Location: Wayne, PA (On-site, 4 days per week)
Employment Type: Contract (W2 through ZipStaff)

About the Opportunity

ZipStaff is seeking a hands-on Senior Network Engineer to support a large enterprise office environment for a major investment-management organization in the Philadelphia suburbs.

You will design, implement, manage, and troubleshoot multi-vendor network technologies, drive network automation, and partner with cybersecurity and workplace technology teams. This is an operations-heavy senior role — not a design-only architecture seat.

What You’ll Do:

Design, implement, support, and optimize enterprise network infrastructure in a multi-vendor environment.
Configure, maintain, and troubleshoot routing and switching.
Support technologies from HPE, Aruba, Cisco, Palo Alto, Zscaler, and similar vendors.
Manage firewalls, secure web gateways, proxy services, and related network-security technologies.
Develop and maintain network automation using Python, Ansible, and related frameworks.
Automate provisioning, configuration management, monitoring, and operational workflows.
Support enterprise wireless / Wi-Fi — deployment, optimization, and troubleshooting.
Troubleshoot complex network performance, connectivity, and security issues.
Partner with cybersecurity on hardening and network-related security initiatives.
Collaborate with desktop support and workplace technology teams on end-user service issues.
Participate in projects covering networking, security, cloud connectivity, and office-technology modernization.
Create and maintain network documentation, standards, and operational procedures.
Use AI-assisted tools (Copilot, ChatGPT, Claude, or similar) to improve operational efficiency where appropriate.

Required Qualifications:

5+ years of enterprise network engineering experience.
Strong knowledge of routing and switching protocols and architectures.
Experience supporting enterprise firewall and network-security technologies.
Hands-on network automation using Python, Ansible, or similar tools.
Experience in multi-vendor networking environments.
Strong understanding of enterprise wireless / Wi-Fi.
Proven ability to troubleshoot complex infrastructure and connectivity issues.
Experience supporting corporate office environments and end-user technology services.
Excellent communication and collaboration skills.
Ability to work on-site in Wayne, PA four days per week.
Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:

Hands-on experience with HPE, Aruba, Cisco, Palo Alto, and/or Zscaler.
Experience supporting large enterprise office environments.
Exposure to cloud networking and hybrid infrastructure.
Familiarity with AI-assisted operational tools.
Experience on cybersecurity or infrastructure-modernization initiatives.
