incident response.
- Design, develop, automate and continuously tune Splunk detection rules, improving alert fidelity, reducing false positives and
expanding visibility across our technology estate.
- Build and enhance automation and AI-driven workflows to improve threat detection, investigation and alert triage, enabling the
team to respond more effectively and efficiently at scale.
- Perform proactive threat hunting using threat intelligence and security telemetry to identify emerging threats, improve
detection capabilities and help shape our Security Operations roadmap.
- Support the administration, configuration and continuous optimisation of our SIEM platform (Splunk), ensuring it remains
resilient, up to date, cost effective and aligned with industry best practice.
