About The Position

AWS customers trust us with their most sensitive data. We're building
cryptographic systems that enhance customer control over access to their data
and metadata. You'll design and implement complex systems using Rust, PKI,
formal verification, and distributed systems that strengthen customer data
protection while maintaining operational efficiency at scale. You'll own
multi-quarter initiatives from design through deployment, building systems that
give customers verifiable control over who accessed their resources and when.
Working as part of the Piezo team, you'll drive security outcomes across AWS
service teams and influence technical direction at the organizational level.
Your work will have CISO-level visibility and shape how tens of thousands of
Amazon builders design and operate their services.

You're a senior software engineer with deep expertise in distributed systems,
security, and large-scale design. You deliver complex initiatives independently,
make sound technical decisions with broad impact, and mentor engineers at
multiple levels. You write exemplary code, conduct insightful code reviews that
raise the quality bar, and debug complex issues across multiple systems. You
communicate technical concepts clearly to diverse audiences and demonstrate
leadership beyond assigned tasks. You influence technical direction and drive
consensus on complex decisions.
