Overview
Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. They work across business groups and around the globe, spanning time zones and disciplines to develop inclusive People policies, forecast finances, give legal counsel, safeguard systems, nurture new initiatives, and more. Every challenge creates possibilities, and we need different perspectives to see them all. Bring yours to Block.
The Role
Advanced Cryptographic Engineering (ACE) builds the infrastructure that safeguards Block's most sensitive data and enables the company to meet its risk and compliance goals at scale. The team's mission is to provide modern cryptographic standards, engineer-friendly key management, and flexible key lifecycles through services and libraries that product engineers across Block rely on daily.
We design and operate systems using proven isolation technologies such as Hardware Security Modules (HSMs) and Trusted Execution Environments (TEEs), ensuring sensitive keys are protected and managed safely throughout their lifecycle. Our customers are Block's internal engineering teams—from Cash App to Square and our goal is to make cryptography simple, scalable, and self-serve so product teams can focus on building while ACE ensures compliance and data protection.
