Cyber Security Engineer (Contract) in London

We are seeking an experienced Cyber Security Engineer to join a growing security function within a confidential technology-focused organisation. This role is designed for an engineer who thrives at the intersection of cyber security, data, and emerging AI technologies. You will play a central role in designing, implementing, and continuously improving security capabilities that are increasingly enhanced by AI-driven detection, automation, and intelligent decision support.

The position combines deep technical security engineering with forward-looking exploration of AI-enabled security systems, detection engineering, and autonomous or semi-autonomous security workflows. You will help shape how AI is used to improve security visibility, accelerate investigation, and continuously adapt to evolving threats.

Working across multiple teams, you will be responsible for building scalable, intelligent, and adaptive security systems that evolve alongside both cyber threats and AI-enabled attack techniques.

• Strong foundation in modern cyber security engineering and detection engineering principles.
• Experience with security monitoring platforms, SIEM systems, and alerting/detection pipelines.
• Strong understanding of identity and access management, endpoint security, logging, network security, and vulnerability management.
• Experience building automation and security workflows using Python, PowerShell, or similar tooling.
• Familiarity with AI-assisted security tools, machine learning concepts for detection, or data-driven security analytics.
• Understanding of how AI can be applied to threat detection, anomaly detection, investigation support, and security operations automation.
• Awareness of emerging AI-driven attack techniques, including adversarial AI and automated exploitation methods.
• Strong analytical thinking with a structured, risk-based approach.
• Excellent communication skills with the ability to translate technical and AI-driven insights into actionable decisions.

Key Responsibilities:

• Design, implement, and continuously improve AI-enhanced security controls across enterprise environments.
• Design, implement, and continuously improve detection engineering pipelines, leveraging both traditional and AI-assisted approaches.
• Build and evolve intelligent monitoring systems that combine rule-based detection with behavioural and AI-driven analytics.
• Develop automation and AI-assisted workflows to improve alert triage, investigation speed, and operational efficiency.
• Work closely with engineering and security teams to integrate AI-enabled security capabilities into operational processes.
• Support incident investigations using advanced analytics, AI-assisted tooling, and structured threat analysis techniques.
• Conduct threat modelling and security architecture reviews with a focus on emerging AI-enabled risks and system complexity.
• Identify vulnerabilities and continuously improve remediation strategies using data-driven insights.
• Evaluate emerging cyber threats, including AI-generated attacks, autonomous malware, and adversarial machine learning techniques.
• Research, prototype, and implement AI-driven security capabilities to improve detection, response, and resilience.
• Design and maintain security standards, engineering patterns, and documentation for AI-enabled security systems.
• Support compliance and governance activities through automated evidence generation and control monitoring.
• Contribute to the long-term strategy for AI-driven security transformation and intelligent security operations.

Minimum Requirements:

• Minimum 5 years of experience in cyber security engineering, detection engineering, security operations, or related technical security disciplines.
• Bachelor's degree in Cyber Security, Computer Science, Information Technology, or equivalent practical experience.
• Familiarity with AI/ML concepts applied to security use cases is highly desirable.
• Experience working with or building automation, analytics, or data-driven security solutions is strongly preferred.
• Demonstrated curiosity and interest in AI, intelligent automation, and next-generation security technologies.

The Cyber Security team is responsible for protecting systems, digital assets, users, and data while enabling the organisation to operate securely at scale and speed. The team focuses on designing, implementing, and continuously improving intelligent security capabilities that integrate automation and AI to enhance visibility, detection quality, and response efficiency.

Security is treated as an important and evolving system—continuously evolving through data, automation, and AI-assisted decision-making—rather than a static set of controls. We are a collaborative and forward-thinking organisation that values technical excellence, curiosity, and innovation. We believe the strongest security outcomes are achieved by combining human expertise with intelligent systems, automation, and AI-driven insights.
