Job Title: Senior Hardware Design Engineer

Reports To: Sr. Director, Hardware & Systems Engineering

Job Function: R & D Engineering

Job Overview: The Senior Hardware Design Engineer architectures, designs, and validates the next generation of high-performance computing platforms tailored for deep-learning infrastructure. This role owns the full lifecycle of complex, high-density PCBs, from schema capture to advanced board-level physical implementation. Positioned at the critical intersection of high-speed digital logic, severe power transience, and extreme thermal dynamics, the engineer ensures maximum system reliability for hyperscale AI deployments.

Primary Responsibilities:

• Accelerator System Design: Architect and implement high-density printed circuit board (PCB) for AI accelerator carrier cards, high-performance host boards, and deep-learning infrastructure.
• Design & Architecture: Own full-lifecycle schematic capture and design optimization for high-density, complex printed circuit boards.
• High-Speed Interface Engineering: Implement, simulate, and optimize high-speed digital and analog circuits using interfaces like DDR4, DDR5, and PCIe Gen 5/6.
• Power & Signal Integrity: Define and optimize robust board-level power distribution networks (PDN) capable of managing massive, transient current steps driven by modern AI logic gates.
• Thermal & Mechanical Reviews: Conduct joint architecture studies with thermal and mechanical engineers to balance extreme compute thermal dissipation with mechanical envelope constraints.
• Validation & Lab Bring-Up: Lead the hands-on bring-up, diagnostic debugging, and physical validation of complex pre-production accelerator hardware systems.
• Yield & Reliability Management: Drive root-cause analyses on structural anomalies discovered during test phases, applying corrective iterations to guarantee target field reliability inside hyperscale deployments.

Qualifications:

• Bachelor's degree in electrical engineering or related field.
• 10+ years of experience as electrical engineer designing high speed digital and analog circuitry on complex high density printed circuit board.
• 5+ years of experience in designing high density boards with fine pitch components and high-density connectors, including expertise in high-speed interfaces such as DDR4, DDR5, PCIe Gen5/6 and microcontrollers and processors.
• Hand-on experience accomplishing system level validation in complex hardware/software environment.
• Strong hand-on debugging skills across system, firmware and hardware domains.
• Proficiency with scripting/programming in python, C or similar languages and understanding product validation methodologies, such as EVT and DVT.

Preferred Qualifications

• DDR4/5 modules, SSD and enterprise storage products design and validation experience.
• Strong understanding of high speed SERDES, equalization technology and PCIe protocols.
• Strong debugging experience using lab tools such as protocol analyzers, oscilloscopes and logic analyzers.
• Mentoring experience or technical leadership in validation team.
• Familiarity with industry certifications, compatibility testing and qualification processes.
• Proficient in collaborating with teams and suppliers to deliver quality products on tights schedules.
