Are you a hands-on Cyber Security Engineer with strong experience in SIEM, threat detection and security automation?

I’m working with a well-established, global financial services organisation looking to appoint an experienced Cyber Security Engineer to join its proactive security function.

This is an exciting opportunity to play a key role in developing and enhancing security capabilities, improving threat detection and implementing preventative security controls across a complex technology environment.

You’ll be responsible for strengthening the organisation’s security infrastructure, developing detection capabilities and driving automation across the security technology stack.

Key responsibilities include:

  • Design, implement and enhance SIEM capabilities, including detection rules, log ingestion and monitoring.
  • Develop and maintain advanced threat detection use cases and proactive threat-hunting capabilities.
  • Build and improve security automation and orchestration (SOAR) processes.
  • Conduct threat modelling, risk assessments and security control reviews.
  • Develop scripts and automated remediation solutions using PowerShell and Python.
  • Work closely with SOC, infrastructure and engineering teams to improve security monitoring and incident response.
  • Integrate and optimise security technologies across cloud and on-premise environments.
  • Support identity-based threat detection, privileged access security and vulnerability mitigation.

What We’re Looking For

  • 5+ years’ experience in Cyber Security Engineering, Security Automation or a similar technical security role.
  • Strong hands-on experience with SIEM technologies, ideally Microsoft Sentinel.
  • Experience developing detection rules, custom queries and threat-hunting use cases.
  • Knowledge of EDR, SOAR and security monitoring technologies.
  • Scripting experience with PowerShell and/or Python.
  • Good understanding of Active Directory security, Windows event logging and network security.
  • Familiarity with cloud security environments such as Azure, AWS or GCP.
  • Understanding of security frameworks including MITRE ATT&CK and NIST.
  • Relevant certifications such as SC-200, AZ-500 or CompTIA Security+ would be advantageous.

Why Consider This Opportunity?

This is a fantastic opportunity for a technically driven security professional who enjoys being hands-on and wants to have a genuine impact on an organisation’s security posture.

You’ll be joining an established cyber security function, working across a varied technology environment with opportunities to influence security tooling, automation and threat detection strategy.
