Security Engineer III
We are seeking an experienced Security Engineer III to design, implement, and improve security solutions across a complex technology environment. In this role, you will help protect infrastructure, applications, networks, and sensitive data by identifying risks, strengthening controls, and responding to emerging threats. You will work closely with engineering, operations, compliance, and product teams to embed security throughout the development and delivery lifecycle.
Key responsibilities include monitoring and investigating security events, conducting vulnerability assessments, supporting incident response, and developing practical remediation plans. You will design and maintain security controls across cloud and on-premises environments, contribute to threat modelling and security architecture reviews, and support identity, access management, encryption, endpoint, and network security initiatives. You will also automate recurring security processes, improve detection and response capabilities, maintain clear technical documentation, and provide guidance on secure coding, configuration, and operational practices. The role may include mentoring less experienced engineers and leading security projects from planning through implementation.
The successful candidate will have substantial experience in security engineering, infrastructure security, application security, or a related discipline, along with strong knowledge of common security principles, frameworks, and industry standards. Experience with cloud platforms, security information and event management tools, vulnerability management, automation, and scripting languages such as Python, PowerShell, or Bash is highly desirable. You should be comfortable analysing complex issues, prioritising risks, and communicating technical recommendations to both technical and non-technical audiences. Relevant professional certifications or equivalent practical experience are advantageous. A proactive, collaborative approach and a commitment to continuous learning are essential.
