Job Description

Our client provides its services within a regulated industry. This position is crucial in implementing and maintaining robust security measures across their infrastructure, as well as managing incident response. The role involves developing, implementing, and sustaining security solutions designed to protect systems against cyber threats, with a focus on transitioning to a zero-trust operating model. The Cyber Security Engineer will be instrumental in implementing security initiatives in collaboration with the Cyber Leads and will play a pivotal role in enhancing the overall security posture. Additionally, the role will support the firm in its pursuit of ISO 27001 certification and the implementation of CIS controls.

Roles Responsibilities (not limited to):

  • Maintenance of the CrowdStrike platform, including configuring EDR policies, tuning SIEM rules, and optimising the system for performance.
  • Work with the network engineers to implement posture management ie ICE/NAC segmentation/lateral movement control and Firewalls.
  • Proactive collaboration with InfoSec to align CrowdStrike and other key security platforms with the security strategy and policies.
  • Leading or participating in incident response efforts, conducting root cause analysis, and developing runbooks for incident handling.
  • Monitoring for security threats, analysing alerts, and responding to incidents using CrowdStrike and other security tools. Conduct vulnerability scans and support remediation and risk mitigation efforts

The successful applicant will be able to demonstrate experience across key security disciplines, including vulnerability management, security operations, incident response, security tools and technologies, risk management, and wider cyber security engineering activities. A strong cyber-security background and a proven track record in security-focused roles is essential, ideally within a regulated industry.
