Senior Power Engineer

RootWave (Ubiqutek) is reducing the use of chemical herbicides in our environment by using electricity to kill weeds. Our technology is the only scalable and sustainable alternative to herbicides which are increasingly under pressure from natural resistance and government regulation.

RootWave has recently received venture investment and is looking to rapidly grow its team. We are looking for a Senior Power Electronics Engineer to help drive the next generation of electrical weed control systems across a multitude of applications.

We take pride in building an innovative company that will improve the environment. We offer working environment that is diverse, inclusive, energetic and challenging. We welcome professionals from all backgrounds with the drive, motivation and tenacity to get the job done.

Role and Objectives
