• Possibilities: Our belief shapes what’s next. Our technology powers the most reliable and energy-efficient connections around the world – and our team powers new products and markets that come next.

Responsibilities

• Understand design intent and develop comprehensive verification & test plans.
• Develop reusable, scalable SV‑UVM testbenches and write test sequences.
• Verify PCIe subsystems and other interfaces (I2C/I3C/SMBus/CPU/UART/SPI) at block and subsystem levels (e.g., PHY, controller).
• Write assertions, checkers, and coverage, analyze functional & code coverage gaps, and drive closure.
• Build firmware‑based simulations in C; mirror/approximate real FW behavior to validate HW/SW interactions.
• Reproduce silicon failures in simulation and perform deep debug to root cause.
• Automate flows with Python/Perl/Shell scripting.
• Collaborate with AEs/FW on debug, feature implementation, and spec contributions driven by DV findings.

Qualifications

• BS/MS in Electrical Engineering, Computer Engineering, or related field.
• 7 years of experience in RTL and functional verification using SV/UVM.
• PCIe verification experience.
• Experience with gate‑level simulation and firmware‑based simulation.
• Proficiency in RTL design and computer architecture concepts.
• Strong debugging, problem‑solving, and analytical skills.
• Effective collaborator who thrives in cross‑functional teams.

Preferred Qualifications

• Background in high‑speed connectivity solutions (PCIe/CXL, SerDes, optical DSP).
• Experience working across HW/SW boundaries and with application engineering/firmware teams.
• PHY verification experience.
