Digit'Eaux acts as the digital transformation partner for public water and sanitation organisations in Wallonia, delivering infrastructure and security projects that must meet NIS2 and ISO standards. This role exists to strengthen the cybersecurity practice by contributing hands-on SecOps work, SIEM/EDR tuning and Azure-based security for multiple public-sector clients, working closely with the CISO and Information Security Officer.
The mission
The security team protects information systems for a consortium of intermunicipal services active in water, sanitation, land use and renewable energy, operating under NIS2 obligations. You will work across on-premises and cloud environments, apply hardening benchmarks (CIS, NIST, ANSSI) and help unify vulnerability management for multi-client MSP environments.
On a day-to-day basis you will participate in operational security (SecOps), manage detection and response tooling, and perform technical security reviews of projects and production estates. You will coordinate with the CISO, the internal security team and client technical teams to qualify SOC alerts, run incident response activities and produce posture reports that support NIS2 and ISO27001 compliance.
Your responsibilities
- Operate and optimise SIEM/EDR platforms, create detection rules, dashboards and automated playbooks that reduce mean time to detect and respond
- Triage and escalate SOC alerts, lead containment and remediation efforts and deliver clear incident reports to stakeholders
- Harden servers, network devices and cloud tenants using CIS/ANSSI/NIST benchmarks and document secure configurations
- Configure and secure client environments including firewalls, VPNs, VLAN segmentation and identity services (IAM/Entra ID)
- Conduct technical security reviews and produce pragmatic remediation plans tied to risk and compliance (NIS2, ISO 27001)
- Produce security metrics and dashboards that inform the CISO and support audit preparation
