We are looking for a senior cybersecurity professional who is motivated not only by technical excellence, but also by the peace of mind that their work brings to clients.

You will be driven by the certainty that your efforts allow our clients to sleep soundly at night, reassured by the security we provide. This role combines advanced technical expertise, strong leadership, mentoring, and a deep commitment to service quality.

You will play a key role in the evolution of our detection and response capabilities by leveraging your expertise in the Microsoft 365 security suite and Microsoft Sentinel, while integrating other major security solutions to build a robust and comprehensive defense strategy. Your goal will be to continuously improve the maturity of our SOC operations and deliver measurable value to our MDR customers.

• Lead complex incident response efforts, ensuring thorough analysis, effective resolution, and clear communication with customers;
• Conduct root cause analysis and provide accurate post-incident reports to internal and external stakeholders;
• Act as a senior escalation point for advanced threats identified by SOC analysts;
• Collaborate with detection engineers to improve detection logic, alert quality, and event fidelity;
• Contribute to playbook development and event tuning to optimize automation and response efficiency;
• Integrate and adapt detection strategies based on emerging threats and attack techniques observed in the field;
• Mentor SOC team members by promoting a culture of excellence, attention to detail, and continuous improvement;
• Foster cohesion and skill development within the L3 analyst team;
• Ensure alignment between detection efforts and actual customer needs, delivering results that build trust and security assurance.

What you bring to the role

• Over 7 years of experience in SOC, detection engineering, or incident response;
• Solid experience with the Microsoft 365 security suite (Defender, Purview, Intune, Entra, etc.) and Microsoft Sentinel;
• Good knowledge of other security platforms and technologies (SentinelOne, CrowdStrike, Palo Alto, Splunk, EDR / XDR tools);
• Experience in malware analysis, reverse engineering, and endpoint threat detection;
• In-depth understanding of detection engineering, security architecture, and incident triage;
• Advanced proficiency in KQL and other investigation tools in cloud and hybrid environments;
• Strong written and oral communication skills;
• Strong attention to detail, with a focus on results that matter to customers;
• Strong sense of responsibility, rigor, and ability to manage complex priorities with calm and clarity;
• Excellent verbal and written communication skills in English and French, with the ability to present complex security concepts to non-technical anglophone stakeholders
