Collaboration across distributed teams and with hardware, software, and architecture colleagues is a key aspect of this role, enabling the sharing of tools and best practices.

Key Responsibilities

• Develop detailed validation test scenarios for OS-based testing, ensuring they cover the necessary features and align with the overall test plan and architecture specifications.
• Configure and bring up OS environments and test payloads on target hardware platforms, execute regression tests, and analyze results to detect functional or stability issues.
• Debug validation failures, whether software, OS, or hardware-related, and perform root cause analysis.
• Document defects thoroughly, including failure analysis, reproduction steps, logs, and supporting evidence, and work with development teams to resolve issues.
• Track validation progress, identify gaps in test coverage or quality, and communicate findings, risks, and status updates to stakeholders.

Qualifications and Skills

• A university degree or equivalent experience in Computer Science, Electronic Engineering, or related fields.
• Experience in software development with C language, along with some knowledge of low-level assembler programming.
• A good understanding of CPU architecture and micro-architecture features such as caches, MMU, SMP, cache coherency, and pipelines.
• Familiarity with operating system kernels and their hardware exploitation techniques.
• Strong debugging skills to analyze complex issues across hardware and software boundaries.
• Excellent documentation skills for defect reporting and analysis.

Desirable Skills

• Experience with ARM instruction set architecture.
• Knowledge of scripting languages such as Python.
• Exposure to CPU verification processes or Electronic Design Automation (EDA) tools.
