- Automating repetitive workflows and response actions using Python, PowerShell, or Azure Logic Apps.
- Establishing strong, trusted relationships with stakeholders across C-suite, corporate, engineering, and business units, clearly communicating risk and business impact.
- Staying ahead of the evolving threat landscape and contributing to long-term cyber strategy and uplift programs.
Experience Needed:
- 4+ years' experience in Security Operations, such as SOC, DFIR, detection engineering, or incident response.
- Proven experience working in complex enterprise-scale environments.
- Experience with Microsoft Sentinel and KQL for threat hunting, detection, and investigation.
- Demonstrated expertise in incident response and leading escalations.
- Scripting and automation experience (Python, PowerShell, Azure Logic Apps).
- Excellent stakeholder engagement skills - comfortable working with C-level leaders, corporate teams, and customer-facing functions.
Why You'll Love This Role:
- Play a key role in shaping the organisation's cyber defence landscape at the corporate level
- Work with leading tech and access ongoing learning
- Partner with leadership to define the cyber strategy, including emerging threats and AI's role in defence.
