Validation Engineer (Pre & Post Silicon Functional Validation)

Job Title (Role): Validation Engineer – Pre & Post Silicon Functional Validation, Compute Subsystem (CSS)

Location: Bangalore

Experience: 2–3 years

Role Overview

As a Validation Engineer in the Compute Sub-System (CSS) team, you will be responsible for validating key subsystem IPs and platform functionality across the pre-silicon and post-silicon lifecycle. You will develop validation solutions, execute comprehensive test plans, debug complex hardware/software issues, and collaborate closely with Architecture, Design, DV, Firmware, and Software teams to ensure high-quality silicon delivery.

Key Responsibilities

• Develop and execute pre-silicon and post-silicon validation plans for Arm's compute subsystems.
• Build and enhance test environments, automation frameworks, and validation infrastructure using emulation and silicon platforms.
• Perform system-level functional validation, focusing on CPU clusters, coherent interconnects, memory controllers, and peripheral integration.
• Drive root-cause analysis of hardware, firmware, and software issues, collaborating with cross-functional teams.
• Develop diagnostic, stress, and performance workloads to validate system functionality, power, and performance.
• Support silicon bring-up and debug activities, including board-level testing and post-silicon lab validation.
• Analyse coverage gaps and contribute to improving validation efficiency and quality metrics.
• Contribute to automation and continuous integration for validation workflows.
  
  

Required Skills And Experience

• 1–3 years of relevant industry experience in SoC, subsystem, or IP-level functional validation.
• Understanding of ARM based SoC architecture, AMBA protocols (AXI/ACE/CHI), cache coherency, and CPU subsystems.
• Proficiency in C/C++ and scripting languages (Python) for test automation and analysis.
• Experience with hardware validation tools (logic analyzers, oscilloscopes, JTAG debuggers) and pre-silicon simulation/emulation environments.
• Good understanding of pre-silicon verification techniques and post-silicon validation challenges.
• Familiarity with C based IP drivers and firmware for system-level bring-up and validation.
• Strong analytical and debugging skills; ability to triage complex hardware/software interactions.
