• Purple Team - Collaborate with our Adversarial Simulation team in Purple Team exercises to test, validate, and improve detection logic and response.

• Incident Response SME support - Act as a Subject Matter Expert during security incidents, providing deep technical analysis and aiding remediation.

• Collaboration - Work closely with the wider Security Operations team, and other stakeholders to uplift Starling’s security posture and improve detective controls.

• Documentation - Maintain clear documentation for detection rules, hunting playbooks, and processes.

• 3+ years in a technical security role, such as detection engineering, threat hunting, incident response, or threat intelligence.

• Attacker Knowledge: Practical experience analysing attacker behavior, with a strong understanding and application of threat analysis models like MITRE ATT&CK to prioritize and enhance detective controls.

• SIEM Expertise: Hands-on experience with SIEM platforms (e.g., Splunk, Google SecOps, Elastic, Sentinel) for rule/query creation and analytics.

• Threat Hunting: Experience conducting proactive threat hunts, defining hypotheses, and developing hunting methodologies.

• Cloud Security: Solid knowledge of security risks and detection strategies for AWS, GCP, Azure.
