Validation Engineer – Post Silicon Functional Validation, Compute Subsystem (CSS)

Arm Limited; Bengaluru; Hybrid; INR 800,000 - 1,200,000; Full time

Job summary

Arm Limited in Bengaluru (India) is seeking a Validation Engineer to design, execute, and improve validation methodologies for Arm’s compute subsystems IPs, pre- and post-silicon bring-up. You will collaborate with design, DV, firmware, and software teams to ensure robust validation coverage.

The role emphasizes building validation solutions, test plans, and diagnostic workloads to ensure high-quality silicon delivery while supporting board-level validation and lab activities.

Qualifications

• 1–3 years of relevant industry 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 languages (Python) for test automation and analysis.
• Experience with hardware validation tools (logic analyzers, oscilloscopes, JTAG debuggers) and pre-silicon simulation/emulation environments.
• Solid understanding of pre-silicon verification techniques and post-silicon validation challenges.
• Familiarity with C based IPdrivers and firmware for system-level bring-up and validation.
• Strong analytical and debugging skills; ability to triage complex hardware/software interactions.

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.
