Hardware Test Engineer

PRI Global; Sunnyvale (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

PRI Global is seeking an experienced EE hardware validation engineer focused on Power Integrity and Signal Integrity. You will analyze data, review reports, and develop robust test procedures, while mapping circuits from schematics to ensure accurate power distribution and probe access.

The role requires strong lab skills with high-bandwidth instruments and a deep understanding of high-speed measurements, DC-DC characterization, and transmission line effects.

Qualifications

• 4+ years of EE hardware validation experience with emphasis on PI/SI.
• Ability to analyze test data, identify root causes, and drive issues to closure with cross-functional teams.
• Experience reviewing test reports for correctness, identifying gaps, and driving follow-up actions.
• Ability to develop test procedures with clear technical writing, SOPs, and annotated diagrams.
• Strong schematic reading skills and tracing signal paths in power distribution.
• PCB layout review experience focusing on probe access and SI/PI risks.
• Expert-level knowledge of lab instruments including high-bandwidth oscilloscopes and spectrum analyzers.
• Experience with DC-DC converter characterization and high-speed digital signal measurements.
• Understanding of transmission line theory and impedance matching in flex PCBs.
• Strong communication to explain EE issues to CM teams and design partners.

Responsibilities

• Analyze test data and drive issues to closure with cross-functional teams.
• Review test reports for accuracy and identify gaps plus follow-up actions.
• Develop test procedures with clear technical writing and diagrams.
• Read schematics to map circuit functions and power distribution.
• Review PCB layouts for probe locations and SI/PI risks.
• Communicate EE issues clearly to CM teams and design partners.

Job description

• 4+ years of EE hardware validation experience with strong emphasis on Power Integrity (PI) and Signal Integrity (SI).
• Proven ability to analyze test data, identify root causes, and drive issues to closure with cross-functional teams.
• Experience reviewing test reports for correctness, identifying gaps, and driving follow-up actions.
• Ability to develop test procedures for execution by others, including clear technical writing, structured SOPs, and annotated diagrams.
• Strong schematic reading skills, including tracing signal paths, understanding power distribution, and mapping circuit functions from schematics and datasheets.
• PCB layout review experience, including assessment of probe access, SI/PI risks, and debug strategy.
• Expert-level knowledge of lab instruments, including high-bandwidth oscilloscopes, power rail probes, active/differential probes, current probes, and spectrum analyzers.
• Experience with DC-DC converter characterization and high-speed digital signal measurements.
• Solid understanding of transmission line theory, impedance matching, and flex PCB signal integrity challenges.
• Strong communication skills with the ability to explain complex EE issues clearly to CM teams and design partners.

Preferred Qualifications:

• Experience working with CMs or ODMs in a validation support capacity.
• Experience with wearable, mobile, or IoT hardware, particularly space-constrained and low-power designs.
• Familiarity with RF measurements, including BLE/WiFi TX power, sensitivity, and antenna return loss.
• Familiarity with proto/EVT/DVT/PVT build cycles and NPI environments.
• Experience with issue-tracking systems and cross-functional coordination in hardware programs.

Technical Knowledge Required:

Power Integrity (PI)

Signal Integrity (SI)

• High-speed interface measurement: MIPI CSI, SPI, I2C, I2S/PDM, USB, and UART.

Schematic & Layout Competency

• Review PCB layouts (rigid and flex) to identify optimal probe locations and debug access points.
