Job Description Summary
Help defend one of the UK's largest organisations against evolving cyber threats. As a Detection & Response Engineer in Lloyds Banking Group's Cyber Defence Centre, you'll play a key role in protecting the organisation from cyber threats by leading complex investigations, identifying malicious activity, and enhancing our detection and response capabilities.
Working alongside experienced cyber defence professionals, you'll act as a technical specialist contributing to the identification, investigation, containment and remediation of security incidents whilst continuously improving how we detect and respond to threats. You'll combine deep expertise with a curious and analytical perspective to solve complex security challenges and strengthen the Group's cyber resilience.
Job Description
This role is an individual contributor and is ideal for an experienced cyber security professional with a passion for threat detection, incident response and continuous improvement. As a senior member of the team, you'll provide technical leadership through expertise, coaching and mentorship rather than formal line management responsibilities.
You'll partner closely with engineers across the Cyber Defence Centre, helping to raise technical standards, share knowledge, and support the development of less experienced colleagues. You'll have opportunities to influence how we detect and respond to threats while remaining hands-on in the investigation of complex security incidents and cyber defence activities.
What you'll do
- Lead complex investigations into security alerts, incidents and emerging threats, driving effective containment, eradication and recovery activities.
- Perform detailed analysis of security events, attacker behaviours and threat intelligence to identify risks and determine appropriate response actions.
- Undertake threat hunting, forensic investigations and proactive cyber defence activities to identify previously unknown threats.
- Contribute to the development and improvement of Cyber Defence by utilising the Continuous Detection Continuous Response (CD/CR) model.
- Use automation, AI and modern security tooling to improve the effectiveness and efficiency of detection and response engineering.
- Mentor and coach Detection & Response Engineers, providing guidance and technical support to help develop team capability.
- Act as a technical role model within the team, sharing lessons learned to drive continuous improvement and engineering excellence.
