Network Engineering information

What are some common challenges network engineers face when managing large-scale enterprise networks?

Network engineers in large-scale enterprise environments often encounter challenges such as maintaining network security across multiple sites, ensuring minimal downtime during upgrades or outages, and troubleshooting complex connectivity issues. Balancing the need for high performance with scalability and cost efficiency can also be demanding. Collaboration with cybersecurity, systems administration, and support teams is essential to address these challenges effectively and to keep the network resilient and efficient.

What is the work of a network engineer?

A network engineer designs, implements, manages, and maintains computer networks such as local area networks (LANs), wide area networks (WANs), and intranets. They troubleshoot network issues, configure hardware and software, and ensure network security using tools like firewalls and VPNs. Certifications like Cisco's CCNA or CompTIA Network+ are often required for this role.

Are network engineers still in demand?

Network engineers are currently in demand due to ongoing growth in IT infrastructure, cloud computing, and cybersecurity needs. They typically require skills in network design, troubleshooting, and certifications like Cisco CCNA or CompTIA Network+ to stay competitive in the job market.

  • 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

  • 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.
