Cyber Security Engineer

</br>

Hedge Fund | Small, High-Impact Security Team | London

</br>

We are partnering with a highly successful investment management firm seeking a Security Engineer to join a small, technically strong security team responsible for protecting critical trading, research, and corporate technology environments.

</br>

This is an opportunity to work in a fast-paced hedge fund where security is viewed as a business enabler rather than a compliance function. You will have exposure across infrastructure, cloud, applications, endpoints, and software engineering teams, helping to build and mature security capabilities that directly support investment operations.

</br>

The role offers significant breadth, ownership, and visibility, making it ideal for an engineer who enjoys solving complex security challenges across multiple domains.

</br>

</br>

• </br>
• Protect and secure Windows and Linux environments across corporate and production infrastructure
• </br>
• Enhance endpoint security controls, monitoring, detection, and response capabilities
• </br>
• Help design, implement, and maintain cloud security controls across Azure and other cloud environments
• </br>
• Partner with software engineers to embed security throughout the Software Development Life Cycle (SDLC)
• </br>
• Drive Application Security initiatives including secure code reviews, threat modelling, and vulnerability remediation
• </br>
• Build and improve DevSecOps capabilities within CI/CD pipelines
• </br>
• Lead vulnerability management activities, including scanning, prioritisation, risk assessment, and remediation tracking
• </br>
• Support incident response investigations and security monitoring activities
• </br>
• Develop security automation to improve operational efficiency and reduce risk
• </br>
• Contribute to security architecture reviews and technology assessments
• </br>
• Work closely with engineering, infrastructure, quant, and investment technology teams to ensure security is integrated into business-critical systems
• </br>

</br>

What We're Looking For

• Experience with application security testing and secure development practices
• </br>
• Strong understanding of vulnerability management frameworks and tooling
• </br>
• Experience implementing security controls within CI/CD pipelines
• </br>
• Knowledge of DevSecOps principles and security automation
• </br>
• Familiarity with authentication, identity management, network security, and encryption technologies

</br>

Why Join?

</br>
