For one of our clients based in Geneva, we are looking for an experienced Security Engineer focused on vulnerability management and patching.

Context

As part of strengthening its security approach, the IT team is seeking an operational profile to support the patching of its systems.

Supporting the existing security engineer, you will be responsible for handling vulnerabilities (CVEs) end-to-end, from analysis to effective remediation, working directly on various environments: Windows, Linux, appliances, applications, and containers.

• Perform patching of Windows servers and workstations directly via SCCM (MECM)

• Patch and remediate Linux systems

• Apply patches on appliances (network, security, storage) and applications, liaising with vendors

• Manage patching of containerised environments: updating, rebuilding, and redeploying images

• Implement workarounds or hardening measures when no patch is available

• Plan interventions: impact analysis, maintenance windows, rollback, post-intervention checks

• Track vulnerability remediation status and document actions taken

Essential skills

• Proven experience in a similar role: operational vulnerability management and patching (mid to senior level, no junior profiles)

• CVE management: reading security advisories, CVSS scores, prioritisation

• Windows patching via SCCM / MECM

• Linux administration and patching

• Updating appliances and applying application patches

• Strong security focus: hardening and mitigation measures

Desirable skills

• Container patching (Docker, Kubernetes) and image scanning

• Vulnerability scanning tools (Qualys, Tenable / Nessus, Rapid7 or equivalent)

• PowerShell / Bash scripting to automate checks and deployments

Personal qualities

• Autonomy, rigour, and sense of priorities

• Ability to intervene in production environments with discernment

• Comfort working closely with a security engineer

• Immediate availability
