Principal Post Silicon Validation Engineer

About the role

About the role Graphcore is establishing a new AI Engineering Campus in Austin where you will help bring next-generation AI processors from first silicon to fully characterized products. As part of the Post-Silicon Validation team within Architecture and Validation, you will lead bringup efforts, mentor engineers, and drive improvements to test infrastructure and processes. This position supports new product introductions and works closely with production software, firmware, and silicon characterization teams. The listing location is Austin, Texas, United States.

Key facts

What you'll do

• Plan, create, and debug silicon validation tests using bare metal C/C++ on FPGA and emulator platforms before first silicon arrives
• Execute validation tests on initial silicon and troubleshoot issues as they arise
• Build automated test frameworks and regression suites in Python to improve validation throughput
• Partner with engineers across multiple disciplines on varied technical challenges
• Collaborate with Validation and Production Test peers to refine test methodologies and implement ongoing improvements
• Analyze test outcomes, isolate failures, and diagnose defects
• Contribute to shared validation and test infrastructure used across teams
• Provide technical feedback to architecture teams
• Lead, mentor, and guide other engineering team members
• Report project status and progress to program management regularly
• Strong background in bare metal and embedded C/C++ development
• Solid understanding of digital ASICs

About Graphcore

Graphcore has built a new type of processor for machine intelligence to accelerate machine learning and AI applications for a world of intelligent machines

Software engineering work usually means turning product intent into systems that run in production. Engineers write and review code, break large changes into reviewable pieces, and watch how those changes behave after they ship. Most teams share on-call or incident habits so outages get a clear owner. Collaboration with product and design is part of the job, not an extra. The duties above are the ones this listing actually states for this opening.
