Description du poste

Security tools only protect anything once they are properly installed, tuned and handed over. A multinational defence organisation in Mons needs a senior, hands‑on engineer to deliver its cyber security capabilities end to end: plan the change, build and test it, document it, and hand it to the people who will run it. On site, with occasional travel to other locations.

• Planning deliveries: writing up designs and change requests and steering them through approval with project managers, engineers and operational stakeholders
• Installing, configuring and testing network tapping and aggregation equipment
• Deploying and tuning vulnerability assessment, forensics and monitoring tools - Tenable.SC, Nessus, Fidelis and Splunk among them
• Applying and validating security settings on Cisco and Juniper kit and on Linux and Windows systems
• Investigating faults and performance problems and putting improvements in place
• Running tests and acceptance, documenting what was built, and handing it over to operations with guides, baselines and training
• Advising on security architecture, tool configuration and integration

What you would bring

• At least five years of hands‑on cyber security engineering
• Broad working knowledge of boundary protection: firewalls, IDS/IPS, traffic aggregation, data diodes, encryption, identity and access management
• Recent experience with Juniper, Palo Alto, web proxies, Splunk, Tenable.SC, Nessus and Fidelis
• Infrastructure design skills across routing, switching and VMware virtualisation
• A track record of delivering security capabilities into live operational environments - installation through to handover
• Excellent English, written and spoken, and a bachelor's degree or equivalent depth of experience
• Nice to have: work for or alongside military or government organisations
