• Identify gaps in logging, detections and security visibility and recommend improvements

• Support vulnerability management activities, including reviewing and prioritising findings

• Translate technical findings into clear customer recommendations and security outcomes

• Contribute to automation, tooling improvements and broader SOC capability development

• Mentor and support junior analysts, helping improve investigation quality and decision-making across the team

• Collaborate with specialist CyberCX teams, including incident response and broader managed security capabilities

• Participate in the team’s rotating after-hours on-call roster What you’ll bring

• Practical understanding of incident response, containment and escalation

• Experience analysing logs and correlating activity across multiple security data sources

• Experience with detection tuning, alert optimisation and ideally developing new detection logic

• Practical threat hunting experience, including working from intelligence, TTPs or suspicious indicators

• A good understanding of attacker behaviours and frameworks such as MITRE ATT&CK

• The ability to look beyond the alert itself and understand the customer, business impact and security outcome
