Senior Power Systems Engineer | Battery R&D

BETA Technologies•South Burlington, VT

1d•$100,000 - $125,000•Onsite

About The Position

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.

Requirements

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

Nice To Haves

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

Responsibilities

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
