Our products span audio CODECs, amplifiers, haptics/sensing devices, power delivery, battery management, and other mixed-signal technologies used in mobile and consumer electronics.
This role is ideal for engineers with early industry experience who are eager to deepen their expertise in mixed-signal silicon validation and lab-based measurement.

Requirements

• BS in Electrical Engineering, Computer Engineering, or related field with 2+ years of relevant industry experience.
• Exposure to silicon validation, mixed-signal characterization, or hardware lab testing.
• Familiarity with analog and mixed-signal circuit fundamentals such as ADCs, DACs, amplifiers, PLLs, and power regulators.
• Experience with scripting or programming for automation (Python, MATLAB, or similar).
• Hands-on experience with common lab equipment such as oscilloscopes, signal generators, power supplies, or spectrum analyzers.
• Strong analytical and problem-solving skills.
• Ability to work collaboratively with engineers across design, systems, and test teams.
• Good written and verbal communication skills.

Nice To Haves

• Experience with audio or power-management IC measurements.
• Familiarity with digital communication protocols such as I2C, SPI, I2S, or TDM.
• Exposure to automated test environments or PXI-based instrumentation.
• Experience working with large datasets and measurement analysis tools such as JMP or Spotfire.
• Interested in developing deeper expertise in mixed-signal silicon validation and measurement techniques.

Responsibilities

• Develop and execute validation and characterization test cases for mixed-signal ICs based on datasheets and system requirements.
• Perform lab-based measurements to evaluate device performance across metrics such as audio quality, noise, dynamic range, power efficiency, and signal integrity.
• Support silicon bring-up and characterization activities under the guidance of senior engineers.
• Develop and maintain automation scripts and test infrastructure for validation and regression testing (Python preferred).
• Use lab instrumentation such as oscilloscopes, signal generators, audio analyzers, and power measurement equipment to evaluate device performance.
• Collect, analyze, and interpret measurement data using tools such as Excel, JMP, or Spotfire.
• Assist in debugging silicon, test setups, and measurement discrepancies in collaboration with design and validation teams.
• Support correlation of lab measurements with production test results and assist with characterization data needed for manufacturing release.
• Document validation results and contribute to reports and presentations for cross-functional teams.
