Validation Engineer – Post-Silicon Functional Validation, Compute Subsystem (CSS)
ArmJob Title
Validation Engineer – Post-Silicon Functional Validation, Compute Subsystem (CSS)
Role Summary
Develop and execute validation methodologies and test plans for Arm compute subsystems across pre-silicon and post-silicon phases. Collaborate with architecture, design, verification, emulation, firmware and software teams to detect, isolate and resolve system-level issues and ensure silicon meets functional and performance requirements.
Experience Level
Entry-level; 1–3 years of relevant industry experience in SoC, subsystem, or IP functional validation.
Responsibilities
Key responsibilities include:
- Develop and execute pre-silicon and post-silicon validation plans for compute subsystems.
- Build and maintain test environments, automation frameworks, and validation infrastructure using emulation and silicon platforms.
- Perform system-level functional validation of CPU clusters, coherent interconnects, memory controllers, and peripheral integration.
- Drive root-cause analysis and debug hardware, firmware, and software issues; support silicon bring-up and board-level testing.
- Develop diagnostic, stress, and performance workloads to validate functionality, power, and performance.
- Analyse coverage gaps and contribute to improving validation efficiency and quality metrics.
- Contribute to automation and continuous integration for validation workflows.
Requirements
Must-have skills and experience:
- 1–3 years' experience in SoC, subsystem, or IP-level functional validation.
- Strong understanding of ARM-based SoC architecture, AMBA protocols (AXI/ACE/CHI), cache coherency and CPU subsystems.
- Proficiency in C/C++ and scripting (Python) for test automation and analysis.
- Experience with hardware validation tools (logic analyzers, oscilloscopes, JTAG) and pre-silicon simulation/emulation environments.
- Familiarity with C-based IP drivers and firmware for system-level bring-up.
- Strong analytical and debugging skills to triage complex hardware/software interactions.
Nice-to-have:
- Experience with emulation systems, CI for validation workflows, or developing performance/stress workloads.
Education Requirements
Not specified.
