Senior Security Engineer, Special Projects

Innovators wanted! Are you an entrepreneur? A builder? A dreamer? This role is part of an Amazon Special Projects team that takes the company’s Think Big leadership principle to the extreme. We focus on creating entirely new products and services with a goal of positively impacting the lives of our customers. No industries or subject areas are out of bounds. We launched products such as Comprehend Medical, Echo Frames and Amazon Explore. If you’re interested in innovating at scale to address big challenges in the world, this is the team for you.

As the Sr. Security Engineer, you will own the end-to-end threat model and translate it into concrete engineering deliverables: hardware attestation for compute nodes, encrypted workload delivery, result integrity verification, API authentication, and workload isolation guarantees. You will work across every component — reviewing the runtime's sandbox model, the scheduler's trust assumptions, the API surface, and the network layer's encryption — to ensure the system is secure by design.

Key job responsibilities
- Author the threat model for the platform architecture, identifying attack surfaces across compute nodes, network transit, and the control plane.
- Design and implement the attestation flow that verifies node integrity before workloads are dispatched, leveraging TPM/TEE where available and defining fallback assurance levels.
- Specify and validate encrypted workload delivery, ensuring model weights and inference inputs/outputs are protected at rest and in transit.
- Build result integrity verification mechanisms, conduct security reviews, lead penetration test preparation, and author compliance documentation.

About the team
Amazon Special Projects is building distributed infrastructure that operates across compute environments Amazon does not fully control. That sentence alone should tell you why this role matters. You will design the trust model that makes this architecture viable: ensuring that workloads are protected, results are verifiable, and the platform meets a bar that earns the confidence of internal and external customers. Security is not a layer we bolt on — it is a constraint that shapes every design decision from day one.

Basic Qualifications

- Knowledge of at least two of the following programming languages: Scala, Java, Python, C/C++, or Go
- Experience (non-internship) in troubleshooting systems issues, analyzing logs, or automating complex tasks using command line tools
- Experience (non-internship) in industry-based security vulnerabilities identification, attack patterns, and remediation techniques
- Experience as a mentor, tech lead or leading an engineering team
- Experience with threat modeling and penetration testing, or experience that includes strong analytical skills, attention to detail, and effective communication abilities and experience in Linux and Networking protocols
- Deep expertise in hardware attestation (TPM, TEE, secure enclaves) and cryptographic protocols
- 7+ years of experience in security engineering, with at least 3 years focused on systems or infrastructure security
- Strong understanding of zero-trust architectures and their practical implementation

- Experience securing edge or distributed platforms where hardware is not under direct organizational control
- Background in secure enclave programming (Intel SGX, ARM TrustZone, or AWS Nitro Enclaves)
- Familiarity with ML model protection, including model watermarking or obfuscation techniques
- Published research or patents in applied cryptography, remote attestation, or secure computation
