About the Role

As a Senior Security Engineer, you will play a critical role in designing and implementing security controls across mobile applications, backend services, and web platforms.

You will help identify vulnerabilities, assess risk, and implement proactive security measures that strengthen the organisation’s overall security posture.

This role is ideal for a security engineer who enjoys working at the intersection of application security, secure architecture, and engineering enablement, helping development teams build resilient and compliant systems.
