Technical Lead - System Tests & Diagnostics Engineer - Austin, Texas, United States
Originally posted 4 September 2026 by the employer. Relisted by the employer on 15 October 2026.
About the role
As a Technical Lead - System Tests & Diagnostics Engineer, you will develop, extend, and integrate specialized silicon validation and diagnostics tools for AI SoCs. You will work with Arm diagnostics technologies and develop system-level diagnostics and stress tools covering CPUs, AI accelerators, memory, storage, and PCIe interfaces.
What you'll do
- Learn and extend existing Arm diagnostics tools to support AI hardware platforms. - Develop specialized diagnostics and stress-testing software for CPU, memory, interconnect, PCIe, and other platform components. - Build reusable validation utilities and configurable diagnostic applications supporting multiple silicon revisions, platforms, and execution environments. - Develop tools to detect and expose intermittent hardware failures, including silent data corruption, timing-related issues, and hardware instability. - Develop automation for executing diagnostics across server and rack-scale validation environments with scalable parameterization. - Debug low-level hardware, firmware, operating system, and driver interactions while collaborating across hardware architecture and validation teams.
What you'll need
- Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline. - Experience developing hardware diagnostics, system validation software, firmware validation tools, or low-level systems software. - Software development skills in Python and C/C++. - Linux systems experience and deep understanding of modern server platform architecture, including CPU, memory, PCIe, storage, networking, firmware, OS, and device drivers. - Experience debugging hardware/software interactions across multiple platform layers and executing server platforms, embedded systems, or SoC validation.
Nice to have
- Experience with Arm-based server platforms, AI accelerators, or high-performance computing systems. - Experience with silent data corruption (SDC) testing, hardware stress testing, power transient analysis, or hardware fault injection methodologies. - Background in firmware validation, silicon bring-up, performance characterization, hardware telemetry, observability, BMC firmware, or RAS technologies. - Subsystem validation experience across CPU scaling, cache behavior, DDR/HBM memory bandwidth and latency, interconnect contention, and PCIe/high-speed I/O.
