Senior Security Engineer, Corporate Services Security

Are you passionate about solving complex security challenges at scale? We are looking for a Security Engineer to join our team and help protect Amazon's products, services, and customers. In this role, you will tackle large, ambiguous security problems - designing and validating security controls, conducting threat modeling, and driving risk mitigation strategies that have broad and lasting impact. You will work across teams to ensure that systems are built securely from the ground up, balancing pragmatic trade-offs with long-term security goals. If you are a collaborative problem solver who thrives in technical depth and wants to shape how security is practiced across an organization, this role offers the opportunity to do meaningful work at remarkable scale.

Key job responsibilities
- Lead security reviews, threat modeling, and architecture assessments for complex systems, identifying risks and guiding teams toward pragmatic, scalable mitigations.
- Design and build security frameworks, runbooks, and rubrics for emerging problem domains, enabling repeatable and consistent security outcomes across multiple teams.
- Partner with product and system owners to proactively design, implement, and validate security controls, ensuring solutions are extensible and have low adoption costs.
- Evaluate source code and system designs to identify vulnerabilities, recommend remediation strategies, and set a culture of secure engineering best practices including authentication, authorization, and least-privilege principles.
- Communicate security risk and design decisions clearly in writing to both technical and non-technical audiences, and mentor other engineers to raise the security bar across the organization.

A day in the life
You might start your morning reviewing a security design proposal from a partner team, identifying gaps in their authentication model and working with them to close those gaps before launch. After that, you could be building out a new threat-modeling rubric that will help dozens of teams assess risk consistently. In the afternoon, you may join an incident response discussion, analyzing root causes and recommending controls that prevent recurrence. Throughout it all, you collaborate with engineers, share your expertise, and help shape the security direction for your organization.

About the team
Our team is committed to maintaining the highest security standards across Amazon's products and services. We work at the intersection of security engineering and product development, partnering closely with builders to ensure that what we ship is secure by design. We value an inclusive team culture where every voice is heard and where engineers at all levels are encouraged to grow. Whether you are refining how we approach risk at scale or mentoring the next generation of security engineers, you will play a key role in our mission to earn and keep customer trust.
