Senior Power Systems Engineer | Battery R&D

At BETA Technologies, we apply our intellectual curiosity, passion for aviation, and commitment to sustainability toward a shared mission of revolutionizing electric aviation. Regardless of the position one holds, each team member brings their talent and desire to positively impact the environment and lives of others in a refreshing, vibrant, and inclusive culture.

We are seeking a Senior Power Systems Engineer to join the Battery team and own the high voltage protection system for ouraircraft—from first-principles analysis through full-scale testing totype-certifiedaircraft. You will adapt coordination models to new configurations, build andmaintain fault analysis models foraircraft-level integration, design efficient test campaigns, analyze test data tovalidate and refine predictions, and summarize findings in reportssubmitted to certification authorities. This position requires a blend of knowledge in electrical engineering, system modeling, test design, and data analysis.AsSenior Power Systems Engineer, you will go deep on a single critical system—high voltage protection— that is essential to helping shape the future of aviation. 

• Develop and maintain the fuse coordination and fault protection models that define how our HV system behaves under every credible fault 
• Design and execute full-scale protection tests — spec DAQ hardware, run the test, and use the data to challenge and refine your models 
• Build battery and protection models that integrate with aircraft-level simulations —enabling system trades grounded in validated physics 
• Partner with the high voltage team on mechanical design — translating insights from the fuse coordination modeling and testing to the aircraft design 
• Collaborate across software, electrical, and systems engineering to support certification efforts 
• Do whatever job is needed to solve problems and make the team better 

• PhD or Master’s +5 years relevant experience  in electrical engineering, physics, or a related field 
• 5+ years of experience with building and validating models of real-world systems in MATLAB / Simulink or Python 
• Familiarity with power systems and high voltage system protections, both active and passive 
• Contributions to HV system design in the EV or other HVDC applications 
• Ability to synthesize large, complex data sets into actionable engineering insights 

• Hands-on experience designing data acquisition systems — selecting sample rates, resolution, filtering, and instrumentation to capture the physics that matters 
• Skill in design of experiments —detailing efficient test matrices that validate models with minimal testing and maximum learning 
• Ability to diagnose model-to-hardware discrepancies — using test data to identify what's missing, what's wrong, and what needs refinement 
• Prior work with aviation certification standards (e.g. ARP 4754 / ARP 4761) or work in other safety-critical environments 
• Experience modeling and system identification of real-world systems in MATLAB and Simulink 
• Communication with DAQ devices, data manipulation and storage 

• Ability to transport yourself to various BETA locations around Burlington as needed 
• Able to work in a dog-friendly and open-office environment 
• Strong interpersonal and communication skills to collaborate with multidisciplinary teams 
• Growth mindset and initiative to own problems, iterate quickly, and deliver practical solutions 
• Desire to learn, experiment, and make others around you better
