Role Description

As a Cyber Incident Response Analyst, you will be a key part of a high performing SOC team, with a desire to continually improve and advance our capabilities to protect SMBC Group. You will bring your passion for Cybersecurity to a team of like-minded professionals and leverage this passion to ensure our monitoring and response capabilities are effective and efficient and that we keep pace with a rapidly changing threat landscape.

You will relish your core role in supporting the monitoring and response of cyber security alerts and incidents by digging into and investigating them to find the root cause and identifying the gap in controls that allowed a threat to reach that point in the kill chain. If you identify an incident, you will lead that technical analysis, tracking down the actions of that threat actor as part of the incident response, while supported by the wider Incident response process and members of the SOC and CSIRT teams. If you identify a false positive, you will drive the effort to tune or refine our detections, or to drive improvements to our preventative controls to prevent a recurrence, freeing more time for the SOC to focus on improving our skills and capabilities. With your knowledge and expertise, you will develop and hone the SOC through work-product review, mentoring, and ownership of projects to develop the technical capabilities of the SOC.

As part of a wider team of SOC analysts, you are able to focus on an area you are passionate about, or if sufficiently experienced, take the lead. You will develop deep expertise and expand our capabilities in domains ranging from across Purple Teaming, Threat hunting, Digital Forensics and Incident Response (DFIR), Security Automation, Detection Engineering and Threat Intelligence and share this knowledge to develop the depth of knowledge of the SOC. As part of a Financial Group with offices and data centers across the Globe, you will have access and exposure to leading technologies and tools. If there is a gap in our toolset, you can help us identify and bridge that gap by acting as Subject Matter Expert to do so. You will bring fresh ideas, challenge the status quo, and seek always to answer - how can we improve?

This role is best suited for candidates who enjoy and have experience within SOC or CSIRT teams and enjoy investigating and finding the root of an issue or incident and working on getting the most from leading edge security toolsets and platforms and processes.
