About the RoleWe are seeking a Sr. Technical Staff to support the post-silicon validation of Cerebras Wafer Scale Engines. In this role, you will test and debug new silicon, develop automation and debug tools, support wafer bring-up and manufacturing operations, and collaborate across hardware and software engineering teams to ensure high-quality system performance.
Responsibilities- Perform post-silicon validation of Cerebras Wafer Scale Engines. Test and debug issues on new silicon.
- Test, analyze, and characterize high-speed serial interfaces to verify compliance with hardware specifications, record performance data, and recommend design modifications to optimize functionality.
- Work with the silicon and operations team to test, bring up, and run burn-in on wafer-scale systems.
- Support manufacturing operations to utilize the wafer bring-up flow. Perform wafer bring-ups, diagnose, and debug problems encountered.
- Develop and implement hardware to ensure compliance with design specifications.
- Collaborate with hardware design engineers and system software engineers to review specifications and recommend changes that will improve the quality and verifiability of the hardware designs.
- Create and maintain automated regression test scripts, using Python and/or Bash, that ensure all tests are run and pass after each change to the design, testbench, tests, or reference model.
- Work with system team members to diagnose system-related failures. Understand the key system interfaces to FPGAs, power, and cooling, and apply that knowledge to the debug of silicon features.
- Develop debug tools in Python to program and analyze the behavior of the Wafer Scale Engine.
- Develop wafer bring-up flow utilizing Python and shell scripts to capture the steps required to bring up a wafer in a logical, easy-to-use flow.
- Document issues found, tools, and flow.
Skills & QualificationsMinimum Requirements- Master's degree or foreign equivalent degree in Electrical Engineering, Computer Engineering, or a related field.
- Three (3) years of experience as an Application Engineer, Sr. Technical Staff, Hardware Engineer, or a related occupation.
- Required Skills
- Electrical Signal Integrity Analysis.
- Hardware Bring-up & Debug.
- Functional and Electrical Characterization.
- Test automation using scripting language.
- High-Speed Interfaces & Protocols, including Ethernet, CPRI, or Interlaken.
