As a Threat Response Engineer, you will lead and improve how we investigate, respond to, and learn from security incidents. This is a senior, hands-on role that combines deep digital forensics and incident response expertise with strong threat intelligence knowledge. You will lead complex investigations, perform forensic analysis, conduct threat hunting, and leverage intelligence to understand who we are up against and how they operate.

You'll help build a mature, intelligence-driven IR capability, focused on the adversaries who target organisations like ours, including state-sponsored actors, well-resourced criminal groups, and attackers making growing use of AI.

What you'll be doing:

• Act as technical lead on our security incidents, owning the investigation end-to-end, from triage and scoping through containment, eradication, recovery, and post-incident review.
• Act as the escalation point for the SOC on confirmed and complex incidents, directing SOC analysts on containment and monitoring during live response.
• Perform digital forensic analysis across endpoints, servers, cloud, SaaS, and identity environments, preserving evidence and reconstructing attacker activity and timelines.
• Use what you find to understand adversary tradecraft, likely objectives, and related activity, and use that understanding to guide scoping and response decisions.
• Work alongside IT, Engineering, Identity, Service Management, legal, privacy, and communications teams during major incidents, and with external incident response partners where needed.
• Rapidly assess emerging threats, zero-days and actively exploited vulnerabilities for real-world exposure across our environment, and drive preemptive response where needed.
• Lead proactive, hypothesis-led threat hunts informed by investigation findings, intelligence, and emerging tradecraft, and work with the SOC to turn the results into tested, high-fidelity detections.
• Produce internal threat reporting that translates what we're seeing in our environment, and across the threat landscape relevant to us, into clear assessments and actions for security teams and leadership.
• Contribute to our threat intelligence capability, including intelligence requirements and the sources and tooling that support them, keeping it directly connected to investigation, hunting, and detection work.
• Expand incident response playbooks, forensic procedures, and evidence handling standards, raise the standard of how we run complex investigations, and coach SOC analysts through live investigations.
• Design and run tabletop exercises for technical and executive audiences.
• Track post-incident remediation actions through to closure.
• Use AI as a core part of how you work, building and applying AI-assisted workflows and automation for evidence collection, enrichment, triage, and analysis, and integrating them with our security tooling.
• Take part in an on-call rota for high-severity incidents.

Key Responsibilities:

• Extensive hands-on experience in digital forensics and incident response, including leading complex, high-severity investigations across hybrid, cloud, and SaaS environments.
• Practical forensic skills across endpoint, memory, network, log, and cloud evidence, with a sound approach to evidence handling and chain of custody.
• An intelligence mindset developed through investigative work: you naturally ask who is behind activity, what they want, and what else they're likely to have done, and you can turn investigation findings into intelligence that drives hunting, detection, and reporting.
• Working knowledge of intelligence analysis fundamentals, such as intelligence requirements, structured analysis and confidence assessments, and how they apply to incident response.
• Experience leading hypothesis-driven threat hunting and converting findings into detections.
• Demonstrable, hands-on experience using AI in security work, such as building AI-assisted investigation or triage workflows, using LLMs to accelerate analysis, or developing automation and integrations, with a grounded view of where it helps and where it doesn't.
• Solid scripting ability (e.g. Python) to support this.
• Good knowledge of SIEM, SOAR, and EDR/XDR platforms and how they support investigation, hunting, and response.
• Strong understanding of attacker behaviour and the MITRE ATT&CK framework, particularly across enterprise, cloud, and SaaS environments.
• Ability to explain complex technical findings clearly and concisely, in writing and in person, to executive audiences, including CISO-level stakeholders.
• Calm, structured judgement during high-pressure incidents, with a drive to share knowledge and raise the capability of the wider team.

Desirable:

• Familiarity with the cybercrime underground, including how criminal forums and marketplaces, initial access brokers, and ransomware ecosystems operate, and experience safely operating and managing research personas.
• Familiarity with intelligence models such as the Diamond Model and F3EAD.
• Relevant certifications such as GCFA, GCIH or GCTI.
• Experience designing or running tabletop exercises or crisis management.
