About the company:

BETA Technologies is creating an electric transportation ecosystem that’s safe, reliable and sustainable. A relentlessly focused team is building an extensive charging infrastructure and ALIA, the world’s most technologically advanced electric vertical aircraft (EVA).

BETA’s platform and products are strikingly simple. Prioritization of safety and a pragmatic approach to certification drive elegant redundancy, appropriate diversity of implementation and simplicity of control. ALIA’s fixed-pitch propellers and centrally located batteries make it an inherently stable aircraft that is safe to fly and easy to maneuver.

The Electric Propulsion Simulation Engineer is responsible for the development, and validation, of the models and simulations which inform our Electric Propulsion System, control systems, and interface design.

As an Electric Propulsion Simulation Engineer at BETA technologies, you will work closely with the electric propulsion team to keep our design models up to date, develop new tests, evaluate different controls methods, and collect the data required to validate the models against the design. This includes modeling of high-voltage, high-power inverters, mechanical systems, and control systems. You will work with the systems, flight sciences, and batteries teams to deliver simulation results and models for accurate aircraft-level simulation.

You will be challenged every day and probably have a lot of fun.
