Responsibilities and Duties
We are seeking a highly skilled System Tests & Diagnostics Engineer to develop, extend, and integrate specialized silicon validation and diagnostics tools for next-generation AI SoCs. Unlike traditional validation roles focused on executing test plans, this position is responsible for developing the diagnostic software and stress tools that expose hardware failures, characterize silicon behavior, and improve platform observability throughout bring-up and validation. You will work closely with Arm engineers to understand and extend existing diagnostics technologies while developing Graphcore-specific capabilities for future AI hardware. Role Summary You will work with existing Arm-developed diagnostics technologies and extend them to support Graphcore's next-generation AI silicon. You will be responsible for developing system-level diagnostics and stress tools that integrate with an existing framework to detect data integrity, computational correctness, performance, and reliability issues across CPUs, AI accelerators, memory, storage, PCIe, firmware, BMC, and other platform components. Examples include silent data corruption (SDC) tests, power transient stress tools, and platform diagnostics, with opportunities to develop new diagnostics as future hardware capabilities evolve. This role requires close collaboration with hardware architects, firmware engineers, validation engineers, and diagnostics teams to understand new hardware capabilities and translate them into reusable diagnostic software.

Responsibilities
Learn and extend existing Arm diagnostics tools to support Graphcore’s AI platform. Develop specialized diagnostics and stress-testing software for CPU, memory, interconnect, PCIe, and other system components. Build reusable validation utilities that integrate into the existing validation framework. Develop tools that expose intermittent hardware failures including silent data corruption, timing-related issues, and hardware instability. Design configurable diagnostic applications supporting multiple silicon revisions, platforms, and execution environments. Develop automation for executing diagnostics across server and rack-scale validation environments. Design configuration-driven diagnostics supporting scalable parameterization and workload variation. Collaborate with hardware architects to understand new hardware capabilities and identify missing diagnostics. Work closely 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 methodologies. Develop software that enables engineers to reproduce and investigate difficult hardware failures. Contribute reusable libraries and utilities that improve engineering productivity across multiple validation teams.
Essential
