Power Systems Engineer, Battery R&D

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.

How you will contribute to revolutionizing electric 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

Minimum Qualifications:

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

Above and Beyond Qualifications:

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

Physical Demands and Work Environment:

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
