On-Site role

Job Description:

  • The FPD Hardware team is seeking a hands-on Contract Hardware Design Engineer to support the development and qualification of HBF Gen1 platform and product. 
  • This role will focus on hardware component qualification, board-level bring-up, design validation, debugging, and schematic support activities. 
  • The ideal candidate will have strong experience with board-level hardware development, power architecture, component validation, and laboratory debugging.

Key Responsibilities

  • Hardware Component Qualification
  • Own and execute qualification of hardware components including:
  • Power management devices (PMICs, DC-DC converters, LDOs)
  • Temperature sensors
  • Oscillators and crystals
  • EEPROMs and other supporting components
  • Develop qualification plans, test procedures, and validation reports.
  • Perform electrical characterization, reliability assessment, and design validation testing.
  • Work with suppliers to resolve technical issues and review component documentation.

Hardware Bring-Up & Debug:

  • Support first-board bring-up activities for Gaia development platforms.
  • Debug board-level issues related to power, clocks, interfaces, and signal integrity.
  • Perform measurements using oscilloscopes, logic analyzers, DMMs, and power analyzers.
  • Root-cause hardware failures and drive corrective actions with cross-functional teams.

Hardware Design Support:

  • Assist with schematic capture, design reviews, and BOM maintenance.
  • Support design updates, ECO implementation, and component substitutions.
  • Conduct schematic checks for power sequencing, sensor integration, and support circuitry.
  • Collaborate with layout, SI/PI, mechanical, and validation teams during product development.

Validation & Documentation:

  • Develop and execute validation plans for new hardware designs.
  • Document qualification results, bring-up findings, and design recommendations.
  • Maintain engineering records and support design reviews.
  • Generate clear technical reports for internal stakeholders.

Cross-Functional Collaboration:

  • Work closely with Hardware Design, Validation, Firmware, ASIC, SIPI, Mechanical, and Component Engineering teams.
  • Participate in design reviews, technical discussions, and issue-tracking activities.
  • Support prototype build activities, lab testing, and qualification execution.

Skills:

  • Strong understanding of:
  • Power supplies and PMICs
  • Temperature monitoring circuits
  • Crystal/oscillator implementation
  • Analog and digital circuit design
  • Experience with board bring-up, debugging, and failure analysis.
  • Ability to read and modify hardware schematics.
  • Familiarity with common interfaces such as I2C, SPI, UART, SMBus, and GPIO.
  • Strong lab skills using oscilloscopes, logic analyzers, DMMs, and power equipment.

Education:

  • BS or MS in Electrical Engineering or related field.
  • 3+ years of experience in hardware design, validation, or board-level development.
