• Proficiency in writing and debugging embedded firmware in C/C++ on microcontrollers (MCUs) and application processors
• Experience with interpreted languages such as Python or JavaScript for automation, scripting, and lab tools
• Solid understanding of RF communications fundamentals (link budgets, antennas, propagation, power management); direct experience with RAIN RFID is a plus
• Hands‑on experience with embedded debug equipment (oscilloscopes, logic/protocol analyzers) and RF test equipment (power meters, spectrum analyzers, vector network analyzers)
• Ability to apply EE and RF fundamentals in analyzing, debugging, and optimizing Reader IC and embedded applications
• Demonstrated ability to take initiative and drive technical outcomes independently, while effectively collaborating across teams to solve complex challenges
• Excellent communication skills with the ability to present technical concepts and results to diverse audiences
