• Maintain and optimize automated regression setups.

Mandatory Requirements

• 1+ years of experience with a Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field

• Strong foundational grasp of advanced computer architecture (pipelines, memory hierarchies, caches).

• Knowledge in System Verilog (SV) and the Universal Verification Methodology (UVM).

• Deep understanding of hardware verification concepts, including constrained-random stimulus generation and coverage-driven verification.

• Familiarity with scripting languages (e.g., Python, Perl, Bash) to automate workflows.

Preferred Qualifications

• Working knowledge of Reliability, Availability, and Serviceability (RAS) architecture.

• Proven experience or familiarity with RAS verification techniques, including error correction code (ECC) testing, parity generation/checking, data poisoning, and hardware fault injection.

• Comprehensive knowledge of the RISC-V Instruction Set Architecture (ISA) and custom extensions.
