Senior Engineer - Design Validation (Python Automation & RF/Wireless Validation)

Overview

Develop Python-based automation and perform RF and wireless validation for Silicon Labs' next-generation wireless SoCs and MCUs, spanning WLAN, Bluetooth, BLE and Zigbee technologies, from pre-silicon FPGA validation through post-silicon characterization and production readiness.

What you'll do

• 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.

What 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.
• Experience with hardware communication interfaces, including UART, SPI, I2C, JTAG, and SWD.
• Strong understanding of electronics, embedded systems, and hardware-software integration.
• Experience in test execution, debugging, data analysis, and validation reporting.
• Familiarity with Git or similar version-control tools.
• Strong analytical, problem-solving, and cross-functional collaboration skills.
• B.E./B.Tech. or M.E./M.Tech. in Electronics & Communication Engineering or a related discipline.

Nice to have

• Hands-on experience with RF test equipment, including signal generators, spectrum analyzers, network analyzers, and oscilloscopes.
• Experience with FPGA-based pre-silicon validation and post-silicon bring-up.
• Exposure to RF PCB boards, wireless MCUs, and SoC validation.
• Experience with Power BI, Python data-analysis libraries, or similar reporting tools.
• Knowledge of RF characterization, modulation testing, regulatory compliance, and wireless performance measurements.
• Experience in temperature-based validation and automated hardware test setups.
• Experience with artificial intelligence (AI) powered tools and technologies used to enhance productivity, analysis, and decision-making.
