Job Description
AWS Utility Computing (UC) provides product innovations from foundational services such as Amazons Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2) to consistently released new product innovations that continue to set AWSs services and features apart in the industry. As a member of the UC organization youll support the development and management of Compute Database Storage Internet of Things (IoT) Platform and Productivity Apps services in AWS including support for customers who require specialized security solutions for their cloud services.
Our Machine Learning Acceleration (MLA) team develops the Inferentia and Trainium SOCs that are used to power todays AI workloads in datacenters all around the world. As a Circuit & Design Analysis engineer youll collaborate with multiple teams to drive improvements in silicon yield & performance its still Day One here at Amazon!
Were searching for an experienced Circuit Design & Analysis engineer with a background in custom circuit design & analysis system level thermal & power analysis with a proven track record of handling challenges at scale. In this role youll be working directly with product engineers signal & power integrity engineers and physical design experts defining best practices driving correlation of presilicon simulation of thermal & power integrity to post silicon analysis and developing custom circuits that help raise the bar in implementing stateoftheart machine learning hardware.
Key job responsibilities
Design and implement custom cells / IP.
Develop & run characterization flows for custom cells / IP developed.
Own integration & postsilicon qualification of IPs like PLL PCIE UCIE HBM sensors/monitors.
Develop scripts to automate running analysis and collect reports.
Develop testplan and perform measurements in the lab to correlate with simulation data.
Be a highlyvalued member of our startup like team through excellent collaboration and teamwork with other physical design engineers product engineers hardware engineers as well as with the RTL/Arch. teams.
A day in the life
Depending on the state of the project you may find yourself working on the following:
Evaluate IPs (like sensors process monitors) from a 3rd party
Develop an characterize custom IPs like ganged buffers custom logic cells for specialized operations (like MACs)
Work with designers and architects to identify painpoints and areas where custom solutions can improve PPAS
Do postsilicon quality checks for key IP like PLLs UCIE/PCIE HBM
Do postsilicon power measurements of jitter sensor calibration power and correlate with simulation
