Security Engineer, Specialized Business Services Cryptography

Role Overview

The Specialized businesses security team at Amazon is responsible for the security of Amazon devices and their connected backend services including Alexa, the Kindle, Fire TV, network systems such as Kuiper and Sidewalk, and Ring devices such as video doorbell, cameras, and lighting. SBS team members are the experts in secure development and implementation, pen‑testing, and the secure development lifecycle.

The Specialized business security Cryptography (DS‑Crypto) team in SBS sets strategic direction for use of cryptography in the SBS organization through research, development, training and consultation. The team is looking for strong crypto security engineers to design, analyze, review, implement, and review implementations of cryptographic solutions in devices and cloud services. You will own the design, analysis and implementation of cryptographic solutions, own key deliverables and have opportunities to extend existing systems and build others from scratch.

You will interact with other Cryptographers, Security Engineers and Applied Scientists and convert their vision into a technical solution. You will participate in the development of guidance and training material regarding secure/proper use of cryptography for other software Builders. This is a high visibility and fast‑paced environment where you will make a direct impact on the customer experience and the bottom line of the company.

We have ambitious goals to build high impact cryptography solutions and to delight our customers with a great product.

• Gather and analyze business and functional requirements, and translate business requirements into technical design specifications.
• Design, review and analyze cryptographic solutions for devices and cloud services.
• Work closely with software development engineers to implement cryptographic solutions.
• Ensure that code developed by you in collaboration with software development engineers is high‑quality, efficient, testable and maintainable.
• Be responsible for technical problem solving, meeting product objectives, and developing best practices.
• Track and report on metrics which are key performance indicators, allowing performance improvements so that the desired outcomes are achieved to plan and in a timely manner.
• Serve as an essential technical resource for builders in Specialized Business teams in the full development cycle of cryptography related software.
• Work in an agile development environment.

The SBS‑Crypto Team researches advances in cryptographic standards and algorithms, serving as experts for post‑quantum cryptography, homomorphic encryption, lightweight cryptography, security protocols, and the implementation of these technologies. When new cryptographic technologies are needed and unavailable, SBS‑Crypto builds (or partners with development teams to build) such capabilities to expand the technology shelf of available solutions. Team members provide the cryptographic expertise for SBS development teams for consultative design exploration and security design reviews.

Cryptography team members contribute to advancing SBS level‑of‑knowledge by developing and leading training classes and adding to the cryptography and devices security body‑of‑knowledge increasing development team’s self‑sufficiency.
