Description du poste

As a Network Security Consultant, you are the technical authority on our network and security engagements. You design, implement and optimize complex multi-vendor environments built around our core stack: Cato Networks (SASE/SSE), Illumio (Zero Trust Segmentation) and our emerging partners.

You operate as a hands-on technical lead: leading delivery on the most demanding projects, mentoring team members, and acting as the third-line escalation point when things get hard. You enjoy the mix of deep engineering, customer dialogue and team enablement.

Our customers operate in a wide range of sectors, from SMEs to multinationals. Together with the team, you are eager to take ownership of the projects and contribute to the continued growth of the netsec team.

Task

• Lead the design, configuration and implementation of complex network and security solutions.


• Act as technical lead on projects: own the end-to-end delivery.


• Optimize the security posture of our customers: review and tighten policies, segmentation models, reference architectures and operational practices.


• Perform expert-level troubleshooting across network and security layers (routing, firewalling, VPN/IPsec, SD-WAN, identity, application traffic).


• Translate business requirements into reference architectures: propose options with clear pros and cons, then guide the customer team through implementation.


• Contribute to pre-sales: shape technical proposals, build and run demos, and represent us in scoping conversations with prospects.


• Automate where it pays off: write scripts and reusable libraries for deployments, configuration management and validation.


• Build reusable assets (documentation, scripts, templates, runbooks) and share best practices to lift the whole team.


• Coach junior colleagues and support their path to excellence.

Profile

• You have experience in network and security consulting or engineering, with a track record of leading delivery on complex customer projects.


• You have expert-level skills in at least two of our core domains: SASE/SSE (ideally Cato Networks), Zero Trust Segmentation (ideally Illumio), or Next-Generation Firewalling (ideally Palo Alto Networks, or equivalent Fortinet / Check Point background you’re willing to convert).


• You have solid fundamentals in routing, firewalling, VPN/IPsec, SD-WAN, BGP, and modern identity-based access concepts (ZTNA, SSO).


• You are comfortable with scripting and automation (Python, Terraform) and can independently build, validate and document new functionality, turning scripts into reusable libraries where possible.


• You can propose a reference architecture from business requirements, defend the trade-offs, and then guide a team through the implementation.


• You communicate confidently with technical and non-technical stakeholders.


• You take initiative: you spot problems, propose solutions, and move them forward without waiting to be told.


• You are a team player who enjoys mentoring, sharing knowledge and lifting others but equally able to work autonomously under pressure.

What we offer

• Salary package Competitive salary package with lots of fringe benefits such as car, insurance, FIP plan, or the possibility of starting as a freelancer.


• Hybrid workplace We offer a flexible hybrid working environment, giving you the freedom to work from home, in the office or at the client's premises, allowing you to strike a good work-life balance.


• Challenging and engaging work Engage in interesting and demanding tasks that allow you to fully utilize and expand your technical talents.


• Training opportunities We offer extensive training opportunities so that you can continuously grow and develop your skills, both through online and on-site training.


• Work-Life Balance We prioritize a good work-life balance with flexible hours and a hybrid work place.


• Team activities We regularly organize team activities to foster a strong team spirit and create an enjoyable working environment.
