Role
The Validation Engineering group is seeking qualified engineers with expertise in Python automation and RF validation/testing. We are looking for Python Automation Engineers who have practical experience in RF/hardware testing and validation of RF/wireless products, specifically related to WLAN, Bluetooth (BT), BLE, and Zigbee standards. The selected candidate will participate in all stages of product validation, including FPGA pre-silicon testing, post-silicon IC package, module, and board-level evaluations. Responsibilities will include conducting both RF and wireless testing.
Meet The Team
The Validation Team serves as an essential interface between the Design team and product datasheet development. This group ensures that products satisfy all specified performance requirements. Upon successful validation, the team compiles the datasheet based on comprehensive characterization data. If the product does not meet requirements, the Validation Team collaborates with Designers to diagnose and resolve underlying issues. The team oversees the full operation of radio systems and associated domains within wireless MCUs, including analog and digital components, peripheral and core elements, RF and baseband signaling, power amplifiers, packet handlers, oscillators, random pattern generators, and various transmitter or receiver functions. Additionally, the Validation Team is responsible for enabling hardware support across all wireless solutions, such as Bluetooth, Zigbee, Wi-Fi, Z-Wave, and proprietary protocols.
Key Responsibilities
- Conduct RF validation and regulatory testing for WLAN, BT, BLE, and Zigbee products.
- Debug RF design and modulation issues for WLAN, BT, BLE, and Zigbee protocols, and collaborate with the design team to resolve them.
- Develop and debug automation scripts in Python for testing and validating products at various temperatures.
- Create Power BI reports from test data, analyse the results, and generate datasheets based on conclusions.
- Perform board-level bring-up and debugging tasks.
Preferred Skills
- 4–6 years of relevant experience in hardware automation.
- Demonstrated proficiency in Python programming, including familiarity with essential libraries and frameworks.
- Comprehensive knowledge of automation frameworks and scripting tools, such as PyTest.
- Solid understanding of hardware communication protocols, including UART, I2C, SPI, and J-Link/JTAG/SWD.
- Proficient in utilising code and script management tools, such as Git.
- Experience in data processing and analysis, particularly using Power BI or similar platforms.
- Strong foundational understanding of electronics principles.
- Familiarity with RF test equipment, including signal generators, spectrum analysers, signal analysers, network analysers, oscilloscopes, and logic analysers, is advantageous.
- Prior experience working with RF PCB boards and FPGA boards is considered an asset.
Qualifications
- B.E/M.E in Electronics & Communication Engineering.
