System Hardware Engineer – Prototype Bring-Up (Profile)

Required: U.S. Person Only

Summary

A System Hardware Engineer specializing in prototype bring-up, debug, and validation
of early-stage hardware platforms. Experienced working in hardware labs with bench-
top instruments to evaluate system performance, identify design issues, and ensure
reliable operation of new devices. Collaborates closely with design, firmware, and
manufacturing teams to accelerate product readiness.

Key Responsibilities

• Prototype Bring-Up & Validation
  • Power-on, configure, and validate first-article prototype boards and
  • subsystems.
  • Perform initial silicon bring-up and evaluate board/system functionality.
  • Debug hardware issues such as signal integrity, power sequencing, timing
  • failures, and component misbehavior.
• Hardware Lab Operation
  • Use standard benchtop equipment including oscilloscopes, digital
  • multimeters (DMM), power supplies, logic analyzers, and function
  • generators.
  • Set up automated test benches for repetitive debugging or data collection.
• Debug & Root Cause Analysis
  • Measure critical signals, rails, clocks, and high-speed interfaces.
  • Interpret schematics, PCB layouts, and datasheets to root-cause failures.
  • Coordinate with PCB layout, EE design, and firmware teams to isolate
  • cross-domain issues.
• System-Level Testing
  • Validate power delivery network (PDN), signal integrity (SI), and thermal
  • behavior.
  • Verify buses and protocols such as I²C, JTAG, and DDR.
  • Characterize device performance, stability, and compliance.
• Documentation & Reporting
  • Document bring-up procedures, test results, and debug findings.
  • Provide clear reports and recommendations for design updates or ECO
  • changes.
  • Maintain lab test logs, configuration notes, and measurement snapshots.
• Cross-Functional Collaboration
  • Work with firmware engineers on bootloader/driver bring-up.
  • Support manufacturing with early DVT/EVT issues.
  • Participate in design reviews and provide feedback for improved testability
  • and reliability

Skill Set

Technical Skills

• Strong understanding of analog and digital electronics.
• Hands-on expertise with oscilloscopes, logic analyzers, power supplies.
• Ability to read schematics, PCB layouts, and use EDA viewer tools (e.g., KiCad,
• Cadence).
• Experience with board bring-up, rework instructions, and component-level debug.
• Familiarity with high-speed interfaces (DDR, AHB, AXI), power rails, regulators,
• and clocking circuits.
• Ability to perform signal probing (single-ended, differential) safely and accurately.
• Basic scripting (Python, PERL) for automation is a plus.

Soft Skills

• Strong analytical problem-solving ability.
• Clear written and verbal communication.
• Ability to work independently in a dynamic hardware lab environment.
• Attention to detail and structured debugging methodology.

Education & Experience
