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
Must have Experience for the following
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 (Must Have)
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 — Must Have
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 (Hands-On)
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/SerDes-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 understanding grounded in design and lab realities.
ASIC I/O, Package, and Power Co-Design
Ability to own or co-own ASIC I/O choices:
I/O standards, voltage domains, ESD strategy, drive/slew tuning, noise coupling/SSO considerations
Strong understanding of package/substrate impacts:
Pinout/ballout tradeoffs, escape routing constraints, lane swapping realities
Package parasitics effects on SI/PI and timing margins
Thermal/mechanical considerations influencing reliability and assembly
Power architecture competence spanning system and ASIC-aware constraints (noise isolation, domain partitioning, bring-up hooks).
DFT / Test Strategy Bridging Silicon ↔ Board ↔ Manufacturing
Strong working knowledge of DFT concepts and productization:
JTAG/boundary scan, scan/ATPG fundamentals, BIST/loopbacks/PRBS, on-chip monitors/telemetry
Experience defining debug and manufacturing test strategy:
Test access, test point strategy, coverage vs SI impact, failure analysis workflows
Analog & Mixed-Signal Practical Depth
Practical capability to own/review analog subsystems relevant to high-performance designs:
Clock generation/distribution and jitter sensitivity
Filtering/biasing, stability fundamentals, measurement integrity/noise coupling
Mixed-signal partitioning and grounding strategy
Hands-On Lab Debug Expectations
Expert in structured bring-up and root-cause debug:
Creation and execution of EVT test plan
High-speed measurement competence (Oscilloscopes, BERT, network analyzers, spectrum analyzers, probing strategy, fixtures, de-embedding awareness)
Ability to correlate bench measurements back to simulation and drive corrective actions
Tools & Workflow
Familiarity with mainstream schematic/layout environments (e.g., Cadence/Altium/Mentor-class tools) and constraint-driven design practices.
Comfortable with SI/PI modeling workflows (IBIS/AMI, S-parameters, SPICE-level reasoning) and validation against lab data.
Strong documentation, design review, ECO, and risk-management discipline.
Leadership & Collaboration
Operates as a cross-functional technical leader across silicon, package, board, validation, test, manufacturing.
Writes clear specs/constraints that prevent rework (I/O requirements, channel budgets, PDN targets, bring-up/test access).
Drives design reviews that identify real risks early and mentors engineers across experience levels.
Drive partnerships with key IP, component and manufacturers.
Evidence of Expertise (What You’ll Be Able to Demonstrate)
Examples where you personally identified high-speed margin failures (examples: 100/200G PAM4 and/or PCIe Gen 6 or slower data rates) through SI/PI analysis or lab testing.
Examples of cross-boundary root cause (ASIC ↔ package ↔ board) with measurable corrective actions.
Examples where you improved observability/DFT/test hooks to accelerate bring-up and production readiness.
Preferred Qualifications (Differentiators)
Advanced packaging or multi-die systems (e.g., chiplets/interposers/HBM-class integration).
Ownership of qualification/compliance (EMC, safety, thermal/mechanical) and production yield improvement.
Experience with design for low cost, second-source strategies, and sustained field reliability initiatives.
