Job description

Senior High‑Speed IO (HSIO) Validation Engineer

This role is responsible for validating HSIO (PCIe/NVLink) subsystems from start to finish, ensuring they meet specifications and deliver optimal performance on GPU‑accelerated platforms.

What You Will Be Doing

• Own HSIO validation of products from test plan development, automation, design for validation, resource planning, coverage metrics, to test execution and bug resolution.
• Coordinate with logic, circuit, board design, simulation, diagnostics, firmware, driver, and marketing teams across time zones to achieve specification compliance and system production readiness.
• Assist in hardware bring‑up and solve tough system‑level issues focused on HSIO.
• Review board schematics, PCB layouts and provide design and component suggestions.
• Ensure interoperability with connected devices and system components in sophisticated interconnect topologies.
• Resolve complex hardware and software HSIO issues on GPU‑accelerated computing platforms.
• Provide engineering support for manufacturing during NPI and MP stages.

What We Need To See

• Ability to work on site in a hardware lab 5 days a week.
• BSEE, BSCE, or equivalent engineering degree.
• 6+ years of HSIO validation experience.
• In‑depth knowledge of HSIO protocols (PCIe, Infiniband, Ethernet) and system‑level operation.
• Experience with logic/protocol analyzers and protocol exercisers.
• Proficient with lab equipment (DSOs, BERT, protocol/logic analyzers) and hands‑on post‑Si bring‑up, functional validation, debug, and tuning of HSIO interfaces.
• Excellent verbal and written communication skills.
• Ability to collaborate across teams and suppliers to deliver quality products on tight schedules.
• Understanding of computing architectures.
• Programming experience with scripting languages such as Python.

Ways To Stand Out From The Crowd

• Demonstrable experience in PCIe physical‑layer debugging (LTSSM) and familiarity with data‑link and transaction layers.
• In‑depth understanding of PCIe (or similar) protocol and post‑silicon characterization/validation methods.
• Strong knowledge of signal‑integrity concepts, silicon characteristics, and high‑speed/SERDES functional validation.
• Experience with datacenter products (system management, security, networking, storage).
• Background with x86/Arm server architectures and accelerated GPU computing.

Benefits

Competitive salary ranges (Level 4: $168,000‑$258,750; Level 5: $200,000‑$322,000) based on location and experience, plus equity and a comprehensive benefits package.
