Cyber Security Engineer

Cyber Security Engineer London | Hybrid (4 days onsite)

About the Company

A fast-growing, technology-led financial services business is looking for a Cyber Security Engineer to join its expanding security function.
Operating within a highly regulated environment, the organisation combines the pace and innovation of a modern tech company with the complexity of enterprise-scale infrastructure. Security is a major investment area for the business, with a strong focus on cloud security, cyber resilience, automation, and intelligent threat detection.

This is an opportunity to join a collaborative team where security is seen as a business enabler — not a blocker.

The Role

This is a hands-on engineering position suited to someone who enjoys solving complex security challenges across modern cloud and enterprise environments.
You’ll play a key role in strengthening detection capabilities, improving visibility across systems, enhancing incident response processes, and driving automation initiatives within a mature but evolving cyber function.

The role offers broad exposure across security engineering, detection engineering, cloud security, incident response, vulnerability management, and security architecture.

Key Responsibilities

• Design, implement, and improve security controls across cloud and enterprise infrastructure
• Enhance SIEM, SOAR, and EDR/XDR capabilities including alerting, tuning, and integrations
• Build intelligent detection and response workflows
• Develop automation solutions using scripting and AI-assisted tooling
• Lead technical investigations and incident response activities
• Improve threat visibility and reduce false positives through detection engineering
• Conduct vulnerability management and remediation initiatives
• Partner with engineering, infrastructure, and DevOps teams to embed security into operational processes and CI/CD pipelines
• Perform threat modelling, security reviews, and risk assessments
• Support compliance and audit initiatives across regulated environments
• Contribute to security standards, documentation, and operational best practices
• Monitor emerging threats and recommend improvements to security posture

Technical Environment

The team works across a modern cloud-first stack with exposure to:

• SIEM / SOAR platforms
• EDR/XDR tooling
• AWS cloud environments
• Identity & Access Management
• Vulnerability Management
• Security Automation & Scripting
• CSPM tooling
• AI-assisted security operations

What We’re Looking For

• 5+ years’ experience within Cyber Security Engineering, Security Operations, or Detection Engineering
• Strong understanding of cloud security and modern enterprise environments
• Hands-on experience with SIEM, EDR/XDR, and incident response workflows
• Experience with scripting or automation using Python, PowerShell, or similar
• Knowledge of security frameworks such as NIST, ISO 27001, SOC 2, or CIS
• Strong problem-solving mindset with the ability to operate across multiple security domains
• Experience within regulated or financial environments is beneficial but not essential

Desirable certifications include CISSP, CCSP, CEH, or AWS Security Specialty.

Why Apply?

• High-impact role within a growing cyber security team
• Strong investment in modern security tooling and automation
• Broad technical exposure across cloud, infrastructure, and security operations
• Opportunity to influence security strategy and engineering direction
• Collaborative and technically progressive environment
• Competitive package and long-term growth opportunities
