Senior Security Engineer I
We are seeking a Senior Security Engineer I to help protect critical systems, applications and data across a complex technology environment. This role will contribute to the design, implementation and continuous improvement of security controls, while working closely with engineering, infrastructure, compliance and operational teams to reduce risk and strengthen resilience.
You will monitor and investigate security events, support incident response activities and help identify, contain and remediate threats. You will also conduct vulnerability assessments, prioritise findings based on business impact and work with technical teams to deliver practical solutions. The role includes reviewing security alerts, analysing logs and forensic evidence, documenting findings, and contributing to post-incident reviews.
Key responsibilities include developing and maintaining security standards, procedures and technical documentation; supporting identity and access management controls; improving endpoint, network and cloud security; and assisting with security architecture reviews. You will contribute to threat modelling, secure design assessments and the implementation of automated security checks within development and deployment processes.
The successful candidate will have substantial experience in information security, security engineering, incident response or a related technical discipline. You should have hands-on knowledge of common security principles, vulnerability management, network security, authentication technologies and cloud security concepts. Experience with security monitoring platforms, endpoint protection, scripting or automation, and infrastructure-as-code will be advantageous.
You will be a confident communicator who can explain technical risks clearly to both specialist and non-specialist audiences. Strong analytical and problem-solving skills, sound judgement and a methodical approach are essential. You should be comfortable managing competing priorities, collaborating across teams and working independently when required. Relevant professional certifications or equivalent practical experience are welcomed.
This is an opportunity to make a meaningful contribution to a mature and evolving security programme, helping to improve defensive capabilities while enabling secure, reliable delivery. The role may include participation in an out-of-hours incident response rota.
