Job Summary
We are seeking an Embedded Audio & ML Application Validation Engineer to validate MCU-based audio, voice, and machine learning applications on target hardware. The engineer will measure and report audio and voice activation KPIs, execute acoustic lab measurements, analyze power behavior, compare firmware-level performance, and document defects and validation outcomes.
Key Responsibilities
Validate MCU-based audio, voice, and machine learning applications on target hardware against test plans and release criteria.
Measure and report power, wake-word or voice trigger behavior, latency, reliability, and related voice activation KPIs.
Perform acoustic lab measurements under defined quiet, noisy, near-field, and far-field conditions.
Execute repeatable test procedures, maintain measurement data, and compare KPIs across firmware versions and configurations.
Support power analysis for always-on and low-power voice activation modes.
Identify and flag firmware regressions or major performance changes.
Perform basic debugging using logs, traces, lab observations,



and measurement equipment.
Document results, KPI trends, issues, observations, and recommended next steps.
Required Technical Skills
Mandatory
4-6 years in embedded validation, application testing, firmware testing, or performance measurement on MCU platforms.
Working knowledge of Python or similar scripting for automation, log parsing, KPI collection, and reporting.
Good C programming knowledge and basic embedded debugging skills.
Basic understanding of MCU architecture, low-power modes, peripherals, and real-time behavior.
Basic hardware knowledge and ability to use lab instruments for board checks and power measurements.
Valuable documentation skills for results, trends, issues, and recommended actions.
Preferred Skills
Exposure to audio or voice use cases such as wake-word, VAD, AEC, noise suppression, or audio front-end validation.
Familiarity with PDM microphones, I2S/TDM, I2C, SPI, UART, DMA, and commo
