Location: At the client’s site (remote work can be discussed with the client)
Employment type: Full-time
Experience level: Mid / Senior (3–7 years)

About the Role

As a Network Engineer, you are responsible for the design, management, and maintenance of our clients’ network and security infrastructures. You ensure that connections are reliable, secure, and perform optimally — both on-premise and in the cloud.

In your consultancy role, you’ll work on-site at one of our clients, often for an extended period. This allows you to help build their IT environment and get to know the organization well, while still enjoying the variety and growth opportunities that consultancy offers — new clients, new environments, new challenges.

Your Responsibilities

• Manage, configure, and optimize network components (routers, switches, firewalls, VPNs)

• Implement network improvements and security measures

• Analyze and resolve network incidents and outages

• Perform network monitoring, capacity management, and performance tuning

• Contribute to migrations, upgrades, and new network projects

• Document changes and provide advice on optimizations

Who You Are

You are an experienced networking professional who thinks in terms of connections — both literally and figuratively. You have an eye for detail, work in a structured way, and enjoy discussing improvements and innovations within infrastructure.

You have:

• At least 3 years of experience as a network administrator or network engineer

• A degree in an IT-related field

• Knowledge of routing & switching, LAN/WAN, VPN, Wi-Fi, and firewalls

• Experience with vendors such as Cisco, HP/Aruba, Fortinet, or Palo Alto

• Experience with network monitoring tools (e.g. PRTG, SolarWinds, Zabbix)

• Basic knowledge of security, cloud networking (Azure, AWS), or SD-WAN

• Certifications such as CCNA, CCNP, CompTIA Network+, Fortinet NSE, or Aruba Certified are a plus

• Good command of Dutch and English (French is an advantage)

• A category B driver’s license

Location

As a consultant, you’ll be assigned to projects at clients throughout Flanders. We do take your region into account. Our consultancy assignments are long-term, typically with one fixed client.

What We Offer

• A permanent contract with Exert

• Varied assignments with leading clients

• Opportunities for professional growth and development

• Training and certification programs

• A competitive salary package with a wide range of extra-legal benefits
