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.
