Job description

We are looking for a skilled Post‑Silicon Validation Engineer with strong electrical engineering fundamentals and hands-on experience in board‑level validation. The ideal candidate must be proficient in oscilloscope‑based signal probing, PCB layout interpretation, and system‑level debugging. This role involves validating silicon behavior on real hardware, performing electrical evaluations, and ensuring interface-level compliance across multiple communication protocols.

Key Responsibilities

• Perform post‑silicon validation, including functional, signal integrity, and power measurement tests.
• Carry out board‑level electrical validation, power sequencing checks, and component-level measurements.
• Review and interpret PCB schematics and layout to plan probing strategy, debug issues, and identify electrical risks.
• Validate serial communication interfaces such as I2C, SPI, QSPI, and MIPI.
• Support board bring‑up activities, including flashing, connectivity checks, and subsystem validation.
• Document test results, create validation reports, and collaborate closely with hardware, firmware, and silicon teams.
• Work with lab instruments such as oscilloscopes, multimeters, logic analyzers, protocol analyzers, and power supplies.

Required Skills & Experience

• Strong understanding of electrical engineering fundamentals, especially digital electronics and board‑level design.
• Hands‑on experience with oscilloscope probing, signal tracing, and waveform interpretation.
• Ability to read and understand PCB schematics and layout files for debug and validation.
• Good knowledge of communication protocols: I2C, SPI, QSPI, MIPI.
• Experience with lab equipment including oscilloscopes, logic analyzers, multimeters, and power analyzers.
• Exposure to board bring‑up, hardware initialization, and early-stage functional validation.
• Ability to debug board‑level issues, including shorts, mis‑routing, signal drops, and interface failures.

Good to Have

• Practical experience in soldering, rework, and fine‑pitch component handling.
• Knowledge in display and LED driver domains, including timing, signal requirements, and functional testing.
• Familiarity with embedded systems, firmware basics, or RTOS‑based workflows.
• Experience with Python or other scripting for automation (optional but beneficial).
