Senior Security Engineer - Security Assurance Scaling

Apple Services Engineering (ASE), the team behind iCloud and Media services and the infrastructure that powers them, is looking for a Senior Security Engineer to partner with engineering teams working on new products and features. You will collaborate with developers, site reliability engineers, and security teams to protect ASE services and design a secure foundation for services at Apple. Your work will include scaling assurance activities, including security risk assessments, threat modeling, and development of security standards. You will work with partner teams in security engineering, privacy, and offensive security to keep Apple's services secure for our users. If you love diving into complex technical systems, sharing security improvements, and making security better, we want to talk with you!

In this role, you will partner with infrastructure and application teams to identify areas where security standards and where security controls should be applied across the ASE organization. You will work with engineering teams throughout their development lifecycle, conduct security reviews, and develop threat models, and using the insights from these engagements to build standard methodologies. As Apple's security risk experts for these services, you will help prioritize which security capabilities and controls need to be applied, and partner with our security engineering team and other platform teams to get them enforced. You will help define, prioritize, and advocate for platform-wide security improvements, raising the security bar for all engineering teams at Apple.

As a technical lead responsible for the security of Apple's internet-facing services and backend infrastructure, you will be:

Innately curious, listening for nuances and digging into details to understand systems and their weaknesses
Able to identify areas ripe for improvement and establish appropriate security goals
Experienced and comfortable establishing relationships with teams to drive security improvements
Current on new security technologies, vulnerabilities, and methodologies
Able to identify opportunities for automated enforcement and partner with security and platform engineering teams to implement them
Able to use data to drive security review efficiency and prioritize high-value security team engagement
Responsible for security decisions impacting millions of users

Minimum Qualifications

8 or more years conducting security reviews, threat modeling, tracking findings, and communicating risk to engineering and leadership
Hands-on experience in cloud security engineering with demonstrated expertise in securing at least one major cloud platform (AWS, GCP, or AliCloud) in production environments
Experience securing cloud-native applications and workloads, including containerized environments (Kubernetes/EKS/GKE), serverless architectures (Lambda/Cloud Functions), and modern CI/CD pipelines
Experience building, evaluating or directing the use of AI/ML-based security tooling to scale secure design review capacity, demonstrating the ability to recognize and act on automation opportunities
Conversant in at least one programming language such as Python, Java, Go, or Swift

Preferred Qualifications

Bachelor's degree or equivalent experience preferred
Experience identifying and prioritizing security enforcement points within infrastructure-as-code (e.g., Terraform, CloudFormation, Pulumi) and CI/CD pipelines, and partnering with platform/security engineering teams to embed controls that apply consistently across many teams, rather than relying on manual, one-off reviews
Familiarity with policy-as-code approaches (e.g., Open Policy Agent, Sentinel, Checkov) sufficient to define control requirements and evaluate proposed implementations for coverage and risk reduction, even if not personally authoring the policy code
