Security Engineer (Threat Response), Sophos Security Team (IDR)

About the job

Role summary

Independently detect, investigate and respond to cyber threats across Sophos and its products, while engineering the detections, automations, reusable skills and agentic workflows that scale Internal Detection and Response. The role combines incident response judgement with security engineering and the safe, measurable and observable use of AI.

What You Will Do

• Own complex investigations across the incident lifecycle, from triage and evidence collection through containment, recovery and lessons learned.
• Act as a trusted front door for security issues, coordinating response across IDR, engineering, product and business teams.
• Perform DFIR and endpoint forensics, including log, network and packet analysis, malware analysis and firewall investigation where applicable.
• Write and improve detections, playbooks, orchestrations and preventions using evidence from incidents and threat hunting.
• Build production-quality automation that removes repetitive work, improves consistency and enables analysts to operate at a higher layer.
• Design model-agnostic, reusable skills and workflows that run across approved AI and agent platforms rather than depending on one model.
