When something gets in, somebody has to be the one who stays calm and works the problem. That is this job.

You would join the incident response team of a multinational defence organisation in Mons, Belgium, under the section head — responding to security incidents around the clock, and helping the wider alliance and its partners do the same.

What you would be doing

• Running incident response — triage, containment, eradication, recovery — in normal hours and on occasional call-out
• Giving technical coordination and support to operating authorities across member and partner nations, non-governmental organisations and industry partners
• Leading or supporting response teams sent out to extend that coverage to one or several physical locations, including on operations and missions
• Building and maintaining the taxonomy behind the branch's information, and the content of the portals that sit on it
• Designing and distributing the reports, briefings and dashboards that business owners, the operational community, service management and security people each need
• Keeping a live network of security peers, so an urgent action can be coordinated when it is needed rather than when it is convenient
• Finding and implementing improvements to the response process as the threats move
• Writing the standard operating procedures and instructions that cover it all
• Acting as the response expert in meetings across the organisation and in an incident task force

What you would bring

• At least four years of hands-on incident response, or a directly adjacent field — digital forensics, threat hunting, or malware and network analysis
• A thorough grasp of computer and communications security, networking, and where modern operating systems and applications actually break
• Recent hands-on intrusion detection and response inside an enterprise-scale response team, ideally against the MITRE ATT&CK framework
• At least three years in information and knowledge management, preferably in security
• Working alongside IT service management
• Very good communication and analysis, and professional English
• Vulnerability assessment and scoring — CVSS, SSVC, coordinated disclosure
• A relevant certification such as CISM, CISSP or a GIAC security qualification
• A bachelor's degree in a related discipline with three years of related experience — or, exceptionally, ten years of progressive expertise in this kind of work

Nice to have

• A degree in cyber or IT security, or information management
• Practical work or research on using AI and language models in defensive security
• Vulnerability management end to end: ingestion, scoring, prioritisation, impact
• An IT service management certification, and depth on security event sources and how to read them
• Hands-on system and network administration, including TCP/IP engineering
• Time in a large organisational response team, and contribution to recognised communities such as FIRST

Why this one is worth a look

Very few response teams operate at this scale or with this reach, and the work is genuinely operational rather than advisory.
