Senior Technologist, Hardware Development Engineering

Position: Senior Technologist, Hardware Development Engineering -
** Company Description*
* WD is building the infrastructure behind the AI-driven data economy.

As AI scales, so does data. Every interaction, every model, every system generates data that must be stored, managed, and made accessible over time. That's where we come in.

We combine deep engineering expertise with global-scale manufacturing to deliver the storage systems that make AI possible, powering hyperscale data centers, cloud platforms, and enterprise infrastructure worldwide.

This isn't theoretical work. It's real systems, at real scale, people solving some of the hardest challenges in technology today.

We're looking for people who want to build, solve, and operate at that level.

Join us and let's shape the future of data.

** Job Description*
* ** We are seeking an Expert-level Hardware Engineer who is equally strong in board-level hardware design and ASIC interface / integration (I/O, package, power integrity, DFT/test, analog, and signal integrity). This is a hands-on role for a recognized subject matter expertise in delivering complex hardware from concept through production, including deep lab bring-up and root-cause complex issues, able to debug across silicon, package, and board.*
* ** Qualifications*
* REQUIRED

+ Professional hardware engineering experience.

+ Proven ownership of multiple complex programs through the full lifecycle: architecture → design → build → bring-up → debug → qualification → production ramp → sustaining.

+ Demonstrated,  _hands-on_  experience spanning both:

+ Board/system hardware design (schematic ownership, layout partnership, bring-up, debug, standards compliance, manufacturing support)

+ ASIC I/O and integration (I/O architecture decisions, package/substrate considerations, PI/SI co-design, tape-out support, DFT/test hooks)

+ Cutting-Edge High-Speed Interfaces

+ Hands-on experience integrating and debugging leading-edge Ethernet and PCIe interfaces, including:

+ 100G/200G Ethernet PAM4 transceivers (system/channel design, equalization concepts, BER/PRBS testing, standards compliance planning and test)

+ PCIe Gen 6 (system/channel design, equalization concepts, BER/PRBS testing, standards compliance planning and test)

+ Demonstrated ability to design and simulate high-speed links across die/ASIC package/PCB/connectors/cabling, balancing SI/PI/EMI and manufacturing constraints.

+ FPGA Board Design

+ Proven experience designing complex boards using cutting-edge FPGAs (e.g., high-end families with high-speed transceivers), including:

+ Power architecture and sequencing for FPGA multi-rail systems

+ High-speed transceiver channel design, with associated reference clock design,

+ reset/boot/strap

+ Bring-up and debug using vendor tools, link training, PRBS/IBERT-style testing, and lab correlation

+ Ownership of FPGA-based platform bring-up from first power-on through high-speed link validation and system integration.

+ AMD FPGA Knowledge preferred

+ Board-Level Design

+ Expert schematic design and review for high-complexity boards (compute/networking/accelerator-class or equivalent).

+ Strong experience with:

+ Multi-rail power distribution networks (frequency domain impedance control, sequencing, fault handling)

+ High-speed interfaces (DDR, PCIe, Ethernet/Ser Des-based links, USB, I2C, SPI, MIPI-based on product needs)

+ Controlled impedance trace design (understanding manufacturing and cost tradeoffs)

+ Clocking/reset/fault tolerant architectures and debug access design

+ General analog circuit design

+ Proven partnership with layout teams to define and enforce:

+ Stackups, reference planes, return paths, via design and strategy, routing constraints

+ Differential pair controlled impedance routing, channel constraints, connector strategy, manufacturability

+ Signal Integrity (SI) & Power Integrity (PI) Across Die / Package / Board

+ SI design experience:
Insertion loss, return loss, eye/jitter concepts, electrical noise abatement, termination, discontinuities, correlation of models to measurements.

+ Deep PI/PDN experience: target impedance approach, decap strategy, anti-resonance mitigation, transient response, measurement and correlation.

+ Practical EMI/EMC grounding/shielding/filtering…
