About the Role
You will extend diagnostics technologies and develop reusable system-level diagnostic and stress-testing software. You will detect and characterize hardware failures across CPUs, AI accelerators, memory, storage, PCIe, firmware, BMCs, and other platform components, while improving observability, automation, and fault isolation.
Requirements
- Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline
- 6+ years of experience developing hardware diagnostics, system validation software, firmware validation tools, or low-level systems software
- Strong software development skills in Python and C/C++
- Strong Linux systems experience
- Strong understanding of server platform architecture, including CPU, memory, PCIe, storage, networking, firmware, operating systems, and device drivers
- Experience debugging hardware/software interactions across multiple platform layers
- Experience developing diagnostics, stress-testing, or hardware validation software
- Experience with server platforms, embedded systems, or SoC validation
- Strong analytical and debugging skills
- Experience collaborating across hardware, firmware, software, and validation teams
- Excellent communication and problem-solving skills
Responsibilities
- Extend existing diagnostics tools for next-generation AI silicon
- Develop diagnostic and stress-testing software for CPU, memory, interconnect, PCIe, and system components
- Build reusable validation utilities within the existing validation framework
- Develop tools to expose intermittent hardware failures, silent data corruption, timing issues, and instability
- Design configurable diagnostics for multiple silicon revisions, platforms, and execution environments
- Automate diagnostic execution across server and rack-scale validation environments
- Collaborate with hardware architects to identify missing diagnostics
- Work with firmware and validation teams to improve hardware observability
- Debug low-level hardware, firmware, operating system, and driver interactions
- Analyze diagnostic output and improve fault-isolation methods
- Develop software to reproduce and investigate difficult hardware failures
- Contribute reusable libraries and utilities for validation teams
