Cyber Security Incident Response & Threat Intelligence Analyst in London

Cyber Security Incident Response & Threat Intelligence Analyst

Team OverviewThe Cyber Security Operations Team is responsible for monitoring, detecting, and responding to cyber threats across Thomas Millers estate. We ensure the protection of digital assets and safeguard confidentiality, integrity and availability of systems. Working in a fast-paced environment, the SOC provides 24/7 vigilance, rapid incident response, vulnerability oversight and actionable threat intelligence to reduce cyber risk

Who Are We Looking For?We are seeking a Cyber Security Incident Response & Threat Intelligence Analyst to strengthen our SOC capability. The successful candidate will focus primarily on incident response while also supporting threat intelligence analysis. This hybrid role ensures we can both react quickly to active threats and proactively reduce risk exposure through continuous threat monitoring and remediation efforts. The ideal candidate will have an in-depth understanding of the overall security landscape, be experienced in cyber security incident response, with a keen ability to detect and respond to complex security incidents, tuning detection systems to spot attacker Tactics, Techniques, and Procedures (TTPs)

They will lead responses to active incidents, collaborating with IT, security, and business stakeholders to mitigate threat actors from our systems as quickly as possiblle.They should have a deep understanding of threat detection techniques, advanced persistent threats (APT), and incident handling procedures. They will provide technical mentorship to junior members of the team, and act as an escalation tier for complex analysis. We are looking for an individual who can balance technical risks against business risks and consistently drive for the right results.

The successful candidate will have a good mix of deep technical knowledge, a demonstrated background in information security, and an analytical mindset that is driven by curiosity.

We value broad and deep technical knowledge, specifically in the fields of operating system security, network security, software security, malware analysis, forensics, security operations, incident response, and emergent security intelligence.
