The Opportunity
We’re working with a leading global financial services organisation to recruit an experienced Security Engineer to join its Proactive Security team.
This is a key role within a mature cyber security function, offering the opportunity to work across security engineering, detection engineering, threat hunting, SIEM, SOAR, automation and security improvement initiatives.
You’ll play an important role in strengthening the organisation’s cyber resilience by designing and implementing security technologies, improving detection and monitoring capabilities, and developing automation that enables teams to respond to threats more effectively.
The role would suit someone who enjoys getting hands-on with technology while also having the opportunity to influence wider security strategy and continuous improvement.

- Build and enhance solutions for proactive threat detection, configuration monitoring and automated remediation.
- Develop and integrate security automation and SOAR capabilities across the security technology stack.
- Design, implement and optimise SIEM capabilities, including data connectors, analytics rules, workbooks, playbooks and automation workflows.
- Develop advanced queries to support threat hunting, investigations, reporting and security monitoring.
- Identify and onboard new security log sources, improving logging coverage across critical infrastructure and applications.
- Troubleshoot log ingestion and data pipeline issues and work with custom log formats to maximise detection visibility.
- Develop and continuously improve threat detection use cases, translating threat intelligence and vulnerability information into practical detection capabilities.
- Conduct proactive threat hunting based on emerging threats, adversary behaviours and attack techniques.
- Improve security visibility across infrastructure, applications, identities and cloud environments.
- Work closely with SOC and incident response teams to enhance detection capabilities and operational readiness.
- Develop security playbooks, operational procedures and automation workflows.
- Provide security engineering expertise across projects, applications and infrastructure initiatives.
- Evaluate new security technologies through proof-of-concepts and gap assessments.
- Contribute to security metrics, control assurance and wider cyber security improvement programmes.
