Context/ROLE

The Threat Engineer Lead is responsible for transforming internal and external threat intelligence into actionable detection capabilities, threat hunting programs, automated response workflows, and AI-driven security operations improvements.

A senior individual-contributor role owning the evolution of Edenred's threat hunting, detection, and response capabilities. The position focuses on proactively identifying threats, engineering scalable and high-fidelity detections and continuously improving incident response outcomes across Edenred's security ecosystem. By applying AI/ML selectively and pragmatically to detection, triage and investigation workflows, the role drives greater speed, precision and operational effectiveness while ensuring robust validation and governance. This is a highly technical leadership role with enterprise-wide influence and no people management responsibilities. The role serves as the critical bridge between Cyber Threat Intelligence (CTI), CSIRT, detection Engineering and security Automation. The successful candidate will design and implement processes, technologies and operating models that enable proactive identification, detection and response to emerging cyber threats.

Position SCOPE & Key Responsibilities

Threat Engineering Lead - Threat Hunting, Detection & Response will:

• Identify opportunities to automate threat intelligence processing, triage, investigation, and response activities
• Own the detection data pipeline and a reference architecture; threat-model current and new systems; evaluate and select tooling; align to MITRE ATT&CK, NIST CSF and ISO 27001 (PCI DSS / DORA where applicable) and report coverage
• Implement detection engineering, test and maintain detections as code; own the false-positive / false-negative lifecycle; map coverage to ATT&CK; favor behavior-based detections; report detection-quality metrics
• AI / ML for threat detection & response - accelerate authoring and translation behind an automated validation harness; automate alert triage and enrichment; apply ML to support anomaly-driven threat hunting and behavioral baselining; always human-in-the-loop, never an unchecked decision-maker
• Partner closely with CTI providers, SOC analysts, incident managers and security engineering teams to transform threat intelligence, incident learnings and emerging threat indicators into enterprise detection and response capabilities
• Lead the development of threat hunting campaigns, detection use cases, behavioral analytics, automated response workflows and security architecture improvements
• Validate outcomes through threat emulation, coverage assessment, detection quality metrics and operational response effectiveness.

Required skills & profile

Experience

• 8+ years across detection engineering, threat hunting and incident response, owning detection content end-to-end
• Splunk experience, EDR experience (CrowdStrike, Defender, TrendMicro), Zscaler experience, Azure experience, AWS experience
• Detection-as-code practice: version control, testing and CI; able to defend detection quality with metrics
• Strong automation in Python (a plus); production security tooling and API integrations
• Demonstrated application of AI/ML to security workflows, with a discipline of validating outputs before production
• MITRE ATT&CK fluency; Windows / Linux / macOS and M365 / Azure / AWS security; security architecture and threat-modelling ability
