Lead Controls Engineer (Power Electronics)

Job Overview

Proper Voltage designs and builds safety-critical battery energy storage systems. This role leads control design for our bidirectional DC/DC power conversion stage — the current and voltage loops, mode transitions, and protection behavior of multiphase interleaved converters — from plant model through validated hardware.

This role sits where power electronics control meets software. You will model the plant, design and discretize the compensators, and prove them in closed-loop simulation running the actual control code. Then you hand the firmware team a design they can implement without guesswork: coefficients, scaling, sample timing, delay budget, limits, and the margins the implementation must preserve.

You will work as a pair with our Lead Firmware Engineer – Power Conversion Control. You own what the loop should do and why; they own how it runs on the silicon. When measured loop gain disagrees with the model, you find out which one is wrong.

What you'll do

• Control design for four-switch buck-boost power stages and successor topologies: current and voltage loops, feedforward, multiphase interleaved operation, and phase current balancing. • Plant models and closed-loop simulation models for each converter, kept current with the hardware and used as the reference for firmware verification. • Operating mode and protection behavior: the transition logic, thresholds, and response-time requirements that firmware implements. • Control design specifications —…
