Senior Security Engineer, AWS Security

Job  | AWS EMEA SARL (UK Branch)

Amazon Web Services (AWS) is the leading cloud provider, offering virtualized infrastructure, storage, networking, messaging, and more to customers worldwide. AWS operates a globally distributed environment at massive scale, enabling businesses—from start-ups to enterprises—to run their operations and applications on AWS’s multi‑tenant infrastructure.

As a Senior Security Engineer, you’ll help build and manage services that detect and automate the mitigation of cybersecurity threats across Amazon’s infrastructure. You’ll collaborate with data scientists, software development engineers, and other security engineers across multiple teams to develop innovative security solutions. Your services will protect the AWS cloud for all customers and preserve their trust.

You will work in a team of industry‑leading security experts serving UK customers to operate and continuously improve security programs and processes. This team manages security programs and processes for personnel security, physical and logical accreditations, education, awareness and training, assurance, and cyber security. The position will have visibility at senior levels of government agencies, commercial institutions, and AWS—interacting directly with CISOs, CTOs, their staff, and AWS senior leadership.

In addition to a strong technical foundation, the role requires an understanding of security technologies, tool development, offensive and defensive tactics, and ideally experience with distributed systems. The team values knowledge sharing and mentorship, with senior engineers, data scientists, and managers actively mentoring junior engineers and colleagues from diverse backgrounds through one‑on‑one mentoring and thorough, kind code reviews.

You will need to be a UK national and able to obtain and maintain a UK Government Security Clearance. For more details, see UK Security Clearance Levels.
