Secondary Skills
  • Ability to analyze complex hardware issues and collaborate across multiple teams.
  • Experience working in cross-functional environments.
  • Exposure to system-level validation and integration.
  • Understanding of silicon bring-up and production ramp processes.
Preferred Qualifications
  • Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field.
  • Experience with CPU or SoC post-silicon validation.
  • Exposure to CPU pre-silicon verification methodologies.
  • Familiarity with CPU instruction set architectures (ISA) such as x86, ARM, RISC-V.
  • Knowledge of manufacturing test and yield improvement.
  • Experience working in Agile or Scrum development environments.
