The Role

In this role, you will develop Python-based automation solutions and perform RF and wireless validation for Silicon Labs' next-generation wireless SoCs and MCUs. You will work across WLAN, Bluetooth, BLE, and Zigbee technologies, ensuring product performance, reliability, and compliance with specifications.

This is a great opportunity for an engineer who enjoys combining Python automation, RF testing, hardware debugging, and silicon validation, with exposure to the complete product lifecycle, from FPGA-based pre-silicon validation to post-silicon characterization and production readiness.

Meet the Team

Our Validation Engineering team plays a critical role in ensuring Silicon Labs' wireless products meet their performance and functional specifications.

The team works closely with Design, RF, Firmware, and Product Engineering teams to validate wireless MCUs and SoCs across RF, baseband, analog, digital, and peripheral subsystems.

We are responsible for developing automated validation solutions, characterizing silicon performance, debugging hardware and RF issues, and generating data-driven insights that contribute to product datasheets and successful product releases.

You will collaborate with cross-functional engineering teams to validate wireless technologies, including Wi-Fi, Bluetooth, BLE, Zigbee, Z-Wave, and proprietary wireless protocols.

Responsibilities

As an Senior Engineer – Design Validation, you will:

• Develop, maintain, and enhance Python-based automation frameworks for RF and wireless product validation.
• Perform RF validation, characterization, and regulatory testing for WLAN, Bluetooth, BLE, and Zigbee products.
• Execute pre-silicon validation using FPGA platforms and post-silicon validation at IC, module, and board levels.
• Develop automated test scripts for RF performance, functional validation, and temperature-based characterization.
• Debug RF performance, modulation, and wireless connectivity issues in collaboration with Design and Firmware teams.
• Perform board-level bring-up, hardware debugging, and system-level validation.
• Interface with hardware using UART, SPI, I2C, JTAG, SWD, and J-Link.
• Work with RF test equipment such as spectrum analyzers, signal generators, signal analyzers, oscilloscopes, and logic analyzers.
• Analyze validation data, develop Power BI dashboards and reports, and support product characterization and datasheet generation.
• Collaborate with cross-functional teams to identify root causes, resolve silicon issues, and improve product performance and reliability.

Skills You'll Need

• 4–6 years of hands-on experience in Python automation, hardware validation, RF testing, or wireless product validation.
• Strong programming skills in Python, including automation scripting, debugging, and test-framework development.
• Experience with PyTest or similar Python-based test automation frameworks.
• Working knowledge of wireless technologies such as Wi-Fi/WLAN, Bluetooth, BLE, or Zigbee.
