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

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

Use Claude, Codex, Copilot and future approved tooling to accelerate investigations, coding, testing, documentation and detection engineering

Contribute through GitHub: create branches, raise and review pull requests, write tests, respond to feedback and support controlled deployment

Instrument agentic workflows with logs, traces, metrics, evaluation results and failure signals so behaviour and outcomes are observable

Apply safe harness design, least privilege, scoped tool access, approval gates, evidence validation, rollback and human review for consequential actions





Communicate incidents, risks, decisions and technical outcomes clearly to engineering and leadership audiences
