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 our aircraft — from first-principles analysis through full-scale testing to type- certified aircraft . You will adapt coordination models to new configurations, build and maintain fault analysis models for aircraft
-level integration, design efficient test campaigns, analyze test data to validate and refine predictions, and summarize findings in reports submitted to certification authorities . This position requires a blend of knowledge in electrical engineering, system modeling, test design, and data analysis. As Senior 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
