Behind the scenes of the world''''''''''''''''s hotels, restaurants, hospitals, and food producers is a company keeping the water clean, the environments safe, and operations running - in over 100 countries. Our client is a global leader in hygiene and infection prevention, and they''''''''''''''''re now investing heavily in the technology backbone behind that mission.

This person must be willing to go onsite to Naperville, IL, 3 to 4 days per week (no on-call schedule!)

This position is a key contributor to an active firewall and VPN cloud-migration effort -transitioning network security infrastructure into a true multi-cloud environment spanning AWS, Azure, and Google Cloud Platform. Deep, hands-on expertise with Palo Alto Networks firewalls and Panorama is essential, as this engineer will play a central role in designing, migrating, and managing firewall and VPN services across cloud platforms.

Key Responsibilities

  • Design, implement, and support cloud network infrastructure, including connectivity, routing, segmentation, and hybrid cloud networking
  • Monitor system and network performance, tuning configurations for better throughput, latency, and resilience
  • Diagnose and resolve platform issues spanning connectivity, outages, and deployments, including on-call support and clear communication during incidents
  • Use scripting and infrastructure-as-code tools to automate deployments, configurations, and patch management
  • Implement security measures per IT policy - access controls, patching, vulnerability remediation - and support disaster recovery testing and restoration
  • Partner with senior engineers, architects, and application teams to plan upgrades, translate business requirements into infrastructure solutions, and maintain technical documentation

Minimum Experience

  • Hands-on expertise with Palo Alto Networks firewalls, including centralized management via Panorama
  • Cloud network engineering experience (AWS, Azure, Google Cloud Platform, or comparable) — virtual networking, routing, connectivity, and security configurations
  • Proficiency in a scripting language (Python, PowerShell, Bash, etc.) for task automation; infrastructure-as-code experience (Terraform, Ansible) preferred
  • Strong troubleshooting skills and broad networking knowledge (LAN/WAN, VPN, DNS, TCP/IP), including root cause analysis across technology layers
  • Experience with server administration, DNS management, and virtualization or cloud environments
  • Solid understanding of IT security principles and backup/disaster recovery strategies
  • Excellent communication skills, with the ability to convey technical information to non-technical stakeholders
  • Relevant certifications (PCNSE, PCNSA, or cloud networking) a plus
