About the Role

Hayfin is seeking a hands-on Cybersecurity Analyst to join their Cloud Infrastructure & Information Security team. This role involves managing the day-to-day security operations of their Microsoft-native environment, acting as a liaison with their managed Security Operations Centre (SOC), and leading incident response from escalation to root-cause analysis. The analyst will have the opportunity to shape the security roadmap and automate routine tasks.

Responsibilities

  • Act as first point of escalation from the managed SOC, leading investigation, containment, and root-cause analysis for Defender XDR and Sentinel incidents.
  • Develop and tune detections and KQL queries, and run threat hunts mapped to MITRE ATT&CK.
  • Harden the Microsoft environment across Entra ID, Intune, Defender for Endpoint, and Azure, and own the vulnerability management lifecycle.
  • Administer email, web, and data security controls, and run the phishing simulation and awareness program.
  • Produce audit evidence and monthly security metrics for ISO 27001, FCA, and DORA obligations, and support due diligence on vendors and portfolio companies.
  • Hold the managed SOC accountable and contribute to the security roadmap.

Requirements

  • Around 3 years' hands-on experience in a SOC, security operations, or security engineering role.
  • Strong practical experience with Defender XDR, Sentinel, Entra ID, and Intune.
  • Demonstrable incident response experience.
