ASIC Test Engineer, Annapurna Silicon Operations

AWS Annapurna Labs develops the silicon used in our most advanced machine learning accelerator servers, utilizing the latest process nodes and massively scaled server clusters to provide the best hardware platform to customers for both inference and training workloads.

We are seeking a semiconductor test engineer with a background in classic ATE platforms to create a clean running extremely low DPPM product-line forming the foundation to our servers.
As our final product is a server, not just the silicon, you will find yourself stretching beyond structural testing and incorporating a lot more mission profile testing, utilizing a variety of external controlling ICs, porting server management and customer run-time software, including the use of virtualized machines and specific microcontrollers found in the end application.

This particular role targets the High Bandwidth Memory (HBM) DRAM interface and memory stack testing, including training of the SOC phy to DRAM base die, stretching beyond JEDEC specs to gain maximum bandwidth with customized training, vendor-specific sequences, lane repair and optimization featuring here.

Your output here will feature in ATE testing, mission profile testing on SLT and full mission profile in the server.
You will understand the interfaces various modes of calibration and training, and how to glean quality of connection from eye diagrams, timing margin etc.

You will also work with the vendors to ingest their production testing patterns and convert/augment to run on the HBMs in final package test using a variety of test interfaces.

You will also have full access to all devices in fleet at any given time and have the opportunity to engage in lifetime test and repair strategies as these devices age and cycle.

As such a curious mindset and an urge to learn system architecture will greatly benefit you in this role.

We are a nurturing and supporting group that will ensure you have access to all tools, code and mentorship needed to become effective in this exciting new way of working!
