Network Security Engineer

Introduction

As a Network Security Engineer at Curios you secure our clients’ network infrastructure — firewalls, segmentation, VPN, NAC and network architecture reviews. This is the network role in our engineering team; our Security Engineer covers platform and identity, and our Cloud Security Engineer the cloud estate. It is client-facing consultancy work across Belgian and international organisations, in Dutch and English.

What you’ll do

• Design, implement and manage secure network architectures for our clients — firewalls, segmentation, VPN and NAC
• Monitor client network environments, identifying and mitigating security risks
• Conduct network vulnerability assessments and security audits
• Review and harden network architecture and connectivity

What we’re looking for

Must have

• At least 2 years in network security
• Experience with firewall management, IDS/IPS and VPN configuration
• Proficiency with network diagnostic, monitoring and analysis tools
• Strong understanding of current cybersecurity trends and best practices
• Professional working proficiency in Dutch and English — you’ll work with Belgian clients in both

Nice to have

• A bachelor’s degree in Computer Science, Information Security or a related field
• Network certifications such as CCNA, CCNP Security or CISSP

What we offer

• A training and certification budget. We’re a team of 48+ certifications and we intend to keep it that way — your next certification is part of the job, not something you fit around it.
• A competitive salary with a 13th month, plus a net expense allowance on top.
• A company car and fuel card — you’ll be moving between client sites, home and our Antwerp office.
• Meal vouchers and eco-vouchers.
• Hospitalisation insurance.
• Phone and laptop.
• A 40-hour week with 12 ADV days, on top of your statutory holiday.
• Hybrid working — home, client sites and the Antwerp office.
• Consultancy work with real variety — Belgian and international organisations, across strategy and hands-on technical work.
