Data Center Hardware Engineering - Hardware System Integration Engineer

As a Hardware System Integration Engineer, you will own the end-to-end hardware engineering lifecycle for high-performance compute designs - from initial specification and schematic capture through board bring-up, validation, and factory build support. You will serve as a critical cross-functional partner to mechanical, power, software, firmware, silicon, and reliability teams, ensuring design requirements are met with precision and at scale.

We’re looking for someone who thrives in a highly collaborative environment, enjoys working across disciplines, and is energized by the challenge of bringing cutting-edge hardware to life.

Responsibilities:

Lead hardware system design and schematic capture for high-performance compute platforms, including board layout guidance and design constraint management

Perform signal integrity simulation, board bring-up, and hands-on debug from system level down to the component or circuit level

Develop and maintain functional specifications, validation procedures, and integration documentation for complex system designs

Execute validation of high-speed digital interfaces (PCIe, Ethernet, USB, DDR, and others) including compliance testing and protocol analysis

Partner cross-functionally with mechanical, firmware, software, silicon, and reliability teams to balance design tradeoffs and meet program requirements

Lead factory build support and sustaining engineering activities through mass production

Drive systematic root cause analysis of complex hardware failures using standard EE lab instrumentation

Apply DFM/DFT/DFA principles throughout the design cycle to ensure reliable, cost-effective manufacturability at scale

Hands-on PCIe, 100-GbE, USB3/USB4, or similar high-speed serial protocol experience, including compliance testing and protocol analyzer debug

Familiarity with computer architecture concepts and hardware design tradeoffs

Experience scripting in Python or similar languages for test automation, data analysis, or lab instrumentation control

Experience engaging vendors and ODM/CM partners, including component vendors and reference design partners, Master’s degree in Electrical Engineering or Computer Engineering

12+ years of relevant industry work experience in hardware or systems engineering

Minimum Qualifications

Bachelor’s degree in Electrical Engineering, Computer Engineering, or equivalent work experience

7+ years of relevant industry work experience in hardware or systems engineering

Deep expertise across common low-speed and high-speed digital interfaces: I2C/SMBus, SPI, JTAG, USB, PCIe, Ethernet (SGMII, RMII, QSFP), and DDR memory

Circuit design experience across multiple domains: power, digital, analog, high-speed communications, and programmable logic

Demonstrated ability to bring up, characterize, and debug complex hardware from the system level down to the circuit level using standard EE lab equipment (DMM, oscilloscope, logic analyzer, spectrum analyzer)

Excellent written, verbal, and visual communication skills, with experience producing functional specs, integration procedures, and technical documentation

High-speed PCB design experience with 10+ layer boards, including PCB material selection and stack-up definition

Proficiency with schematic entry and high-speed PCB layout constraint management using Cadence tools or equivalent
