Senior Security Engineer

Reference: 3o4wyqb912j8nl9if45t

We are seeking a Senior Security Engineer to strengthen the organisation’s ability to prevent, detect and respond to cyber threats across a complex technology environment. In this role, you will design, implement and continuously improve security controls across cloud platforms, networks, endpoints, applications and identity services. You will work closely with infrastructure, software engineering, operations and risk teams to embed security into the design and delivery of new services.

Your responsibilities will include leading security assessments, threat modelling, vulnerability management and incident response activities; investigating alerts and coordinating remediation of identified weaknesses; developing detection and response use cases; and maintaining security standards, procedures and technical documentation. You will contribute to security architecture reviews, advise on secure configuration and engineering practices, and support audits and regulatory requirements. The role will also involve mentoring less experienced colleagues, promoting security awareness and helping to define practical, risk-based improvements across the wider technology estate.

Applicants should have substantial experience in a security engineering, blue-team or infrastructure security role, with strong knowledge of network security, identity and access management, endpoint protection, vulnerability management and security monitoring. Experience with public cloud environments, SIEM and SOAR platforms, automation or scripting, and common security frameworks will be highly valued. You should be comfortable analysing complex incidents, communicating technical risks to both technical and non-technical audiences, and prioritising work in a fast-moving environment. Relevant professional certifications are advantageous, but demonstrable practical expertise, sound judgement and a commitment to continuous learning are equally important. The successful candidate will be collaborative, curious and capable of balancing robust security with usability, resilience and business needs.
