Senior Security Engineer, AWS Security

Reference: qza9c5d6meap4xe32596

We are seeking a Senior Security Engineer to help design, implement, and continuously improve security capabilities across cloud infrastructure and services. In this role, you will work with engineering, operations, compliance, and product teams to protect highly available systems, strengthen security architecture, and manage risk across the organisation. You will provide technical leadership on complex security initiatives and help establish scalable, automated controls that support secure delivery at pace.

Key responsibilities include designing and reviewing cloud security architectures; developing identity and access management strategies; implementing controls for network, data, application, and infrastructure security; and improving monitoring, detection, and response capabilities. You will investigate security events, lead root-cause analysis, and coordinate remediation of vulnerabilities and misconfigurations. The role will also involve building security automation using infrastructure-as-code, scripting, and security tooling; contributing to incident response exercises; supporting audits and compliance activities; and creating clear technical documentation, standards, and guidance. You will mentor engineers, promote secure-by-design practices, and communicate security risks and recommendations to both technical and non-technical stakeholders.

Applicants should have significant experience in cloud security engineering, with strong knowledge of AWS services and security best practices. You will ideally bring hands-on experience with IAM, VPC networking, encryption and key management, logging and monitoring, vulnerability management, container or serverless security, and security information and event management platforms. Experience with Terraform or similar infrastructure-as-code tools, Python or another scripting language, CI/CD security, and threat modelling is highly desirable. Relevant professional certifications are welcome but not essential. We are looking for a pragmatic, analytical engineer who can operate independently, influence across teams, manage competing priorities, and turn security requirements into practical, resilient solutions.
