🎯 The Role

This role will focus on characterizing vertical GaN devices for a variety of target applications using both on-wafer and packaged device test setups. You will have opportunity to be hands-on in shaping the development of a world-changing power electronics, and your contributions will directly impact the success of the company and the industries we aim to disrupt. We have a preference for candidates who are able to work from our office at Greentown Labs (Somerville, MA), but are open to considering hybrid candidates.

✅ Key Responsibilities

• Characterize vertical GaN devices for a variety of target applications using both on-wafer and packaged device test setups.
• Design circuit boards for packaged device tests such as UIS and switching performance.
• Ensure compliance with JEDEC qualification standards (HTRB, HTGB, TDDB, thermal cycling, etc.) and their evaluation.
• Analyze data and automate measurements using python/MATLAB or similar tools.
• Extract key power device parameters for data sheets.
• Work with schematic entry, circuit simulation, and PCB layout tools.
• Collaborate effectively across cross-functional teams and with external partners.

📌 Required Qualifications

• Master’s degree or PhD in electrical engineering with a focus on power device design/characterization or 5+ years of relevant industry experience.
• Deep knowledge of electrical characterization of power devices (IV, CV, pulsed IV, gate charge, etc.) using high-voltage test instrumentation and curve tracers for on-wafer probing with semiautomatic probe stations.
• Familiarity with JEDEC qualification standards (HTRB, HTGB, TDDB, thermal cycling, etc.) and their evaluation.
• Strong computer skills with proficiency in python/MATLAB or similar for data analysis and measurement automation.
• Well-versed in key power device parameter extraction for data sheets.
• Experience with schematic entry, circuit simulation, and PCB layout tools.
• Desire to work in a highly-collaborative, fast-paced startup environment.

⭐ Desirable Experience

• Power circuit design experience with GaN or SiC.
