  • Work within established configuration and change management policies to ensure awareness, approval and success of changes made to the network infrastructure
  • Select and implement security tools, policies, and procedures in conjunction with the company's security team
  • Liaise with vendors and other IT personnel for problem resolutions
  • Ensure security and compliance with policies and procedures
  • Provide technical support and troubleshooting to resolve network related issues
  • Stay updated with the latest trends in networking
  • Document and maintain network environment configurations and diagrams
  • Provide assistance and mentoring to other IT team members
Qualifications:

Must Have

  • 10+ years of experience as a Network Engineer
  • 5+ years of experience in a senior role
  • Deep understanding of network protocols (e.g., IPSEC, HSRP, BGP, OSPF, 802.11, QoS)
  • Solid understanding of the OSI or TCP/IP model
  • Hands-on experience with monitoring, network diagnostics and network analytics tools
  • Advanced troubleshooting skills
  • Experience with both on-premises and cloud (Azure preferred) networks
  • Experience deploying, managing, and troubleshooting firewalls
  • Experience deploying, managing, and troubleshooting VPN IPSEC tunnels
  • Professional certifications in networking
  • Effective communication skills (written and verbal)

Would be a Plus

  • Experience deploying, managing, and troubleshooting an IPS/IDS
  • Experience with Fortinet network devices and firewalls
  • Experience designing and managing networks to optimize VoIP traffic
  • Experience with F5 BigIP devices
  • Bachelor's degree in Computer Science, Engineering, or a relevant field

This is a home office-based position, with some travel for company/salesmeetings as well as to client sites. Flexibility to work outside of standard 9am-6pm local time zone hours may be required at times to support this global team.

Target Base Salary: $90,000K-$100,000K (based on experience) plus variable commissions.
