Collaboration, communication, ownership, and impact are core to how our client works.

Your key responsibilities

Proactively conduct intelligence-led threat hunting and emulation based on emerging threats, adversary activity, and major external cyber incidents.

Translate hunt outcomes into actionable improvements for detection, prevention, and defensive architecture.

Map findings to MITRE ATT&CK; to clearly articulate threats, gaps, and priorities.

Communicate investigation outcomes in clear, executive-ready reports that support risk-based decision-making.

Leverage automation, AI-assisted analytics,



and Breach & Attack Simulation (BAS) to continuously validate threat hypotheses, test adversary techniques, and prioritise high-risk attack paths.

What are we looking for?

Experience with threat hunting methodologies, such as TaHiTi, PEAK, or others.

Proven experience in large enterprise environments, with technologies such as CI/CD, multi-cloud and containers.

Ability to translate threat intelligence into concrete, high-impact investigations.

Skill in identifying and validating meaningful security gaps rather than chasing alerts or noise.

Capacity to think and reason like an adversary while emulating attack scenarios.

Ability to deliver investigation outcomes that improve detection, controls, or resilience.

Clear communication of complex threats to both technical and non-technical stakeholders.

Ability to work effectively in an environment with ambiguity, autonomy, and high trust.
