# Senior Engineer, SoC HAL

Annapurna Labs builds the custom silicon at the heart of AWS machine learning servers, and we are hiring a senior engineer to own the architecture of the Hardware Abstraction Layer (HAL) that brings these chips to life. If you love working where hardware meets software, writing the code that boots, configures, and debugs some of the largest custom silicon in the world, this is your team. As a Software Development Engineer III on the SoC HAL team, you will set the software architecture for the driver stack across multiple hardware blocks and chip generations, partner directly with the hardware designers who build the silicon, and raise the engineering bar for a small, fast-moving team inside a large organization. No machine learning background is required (you will pick up ML concepts from colleagues if you want to). This role can be based in Cupertino, CA or Austin, TX. Key job responsibilities - Own the design and end-to-end implementation of the HAL/driver software architecture for new chips, including the abstractions, interfaces, and patterns the rest of the team builds against. - Apply hardware/software co-design principles, partnering early with RTL designers and design verif
