Red Team Operator (Cyber Resilience)

Reference: a2chg7mw1xsz12fm8z4o

As a Red Team Operator (Cyber Resilience), you will help assess and strengthen the organisation’s ability to prevent, detect, respond to and recover from sophisticated cyber threats. Working as part of a collaborative security function, you will plan and deliver authorised adversary simulation exercises that test people, processes and technology across a range of scenarios.

Your responsibilities will include developing realistic attack plans based on current threat intelligence, conducting red team and purple team activities, and emulating the tactics, techniques and procedures used by relevant threat actors. You will assess controls across networks, cloud environments, applications, endpoints, identity services and operational processes, while maintaining strict adherence to agreed rules of engagement and legal requirements.

You will work closely with security operations, infrastructure, engineering, risk and business stakeholders to validate detection and response capabilities. This will involve documenting findings, evidencing attack paths, assessing business impact and producing clear reports for both technical and senior audiences. You will also support post-exercise reviews, recommend practical improvements and help track remediation through to completion. Where appropriate, you will contribute to incident response exercises, crisis simulations and wider cyber-resilience testing.

Applicants should have practical experience in red teaming, penetration testing, adversary simulation, security testing or incident response, with a strong understanding of common attack methodologies and defensive controls. Experience with scripting or programming languages such as Python, PowerShell or Bash, together with familiarity with cloud platforms, Active Directory, networking and security tooling, is desirable. Relevant professional certifications are welcome, but demonstrable capability and sound judgement are equally important.

You will need excellent communication skills, a methodical approach and the ability to operate discreetly in complex environments. The successful candidate will be curious, adaptable and comfortable challenging assumptions while building constructive relationships. A strong commitment to ethical conduct, confidentiality, continuous learning and responsible vulnerability handling is essential.
