Imagine what you could do here. At Apple, we believe privacy is a fundamental human right. The Crypto Services team is at the center of this commitment, building the secure foundations that protect the Apple ecosystem and the data of over a billion users.

We are looking for a collaborative and innovative Software Engineer to help us design the next generation of security infrastructure.

In this role, you will build robust, scalable software that interfaces with specialized security environments, ensuring that our cryptographic services remain not just current, but ahead of the curve.

Description

The Crypto Services team is responsible for maintaining a number of core Apple security services with various underlying highly-sensitive cryptographic keys. To do this, the team leverages a number of Hardware Security Module (HSM), and HSM-like technologies.

Great care is required in implementing and maintaining these technologies. As a Software Engineer on the Crypto Services team, you will play a critical role in designing, implementing, and maintaining custom software solutions that facilitate the use of these HSM platforms in Crypto Services. Cryptographic standards are constantly evolving, and in this role you will proactively engineer the solutions that allow the team (and thus the team's cryptographic services) to keep pace with the latest cryptographic protocols and standards.

A immediate focus will be strategizing and then implementing solutions to support the newest developments in post-quantum cryptography (PQC) standards. Custom software dealing with HSMs can be challenging to maintain & test. To keep quality standards high, in this role, you will own the design, implementation, and maintenance of HSM testing frameworks, tooling, and infrastructure. You will take ownership of projects, work closely with your fellow engineers to identify sustainable approaches, and find ways to improve performance and security of the tooling.

This is an opportunity to work on problems that matter protecting user privacy and security in a post-quantum-cryptography world while facilitating construction & upkeep of the platforms and tools that multiply the effectiveness of talented engineers across Apple.","responsibilities":"Design, develop, and maintain software solutions that enable the secure and reliable use of Hardware Security Module (HSM) platforms across Crypto Services
