The Role:

The Power Electronics Centre of Excellence (PECoE) seeks to hire a Senior Power Electronics Engineer. The primary focus of this Centre of Excellence is to design a range of custom motor drives (variable frequency) to surpass efficiency, usability and reliability requirements for a wide range of water applications. With one of the locations being with a world-class Cambridge-based consultancy, Sentec, we are supported by excellent facilities and superb access to its scientific experience and expertise whilst maintaining our constant focus on the design of motor drives.

As a Power Electronics Engineer, you shall be responsible for the power electronics and motor control for a range of variable frequency drives used within the Xylem portfolio. These products shall be based upon a re-usable platform which is customizable for specific applications and environments. Typical motor types used with these products shall be conventional asynchronous TEFC motors connected to water pumps, PMSM wetted rotor circulator
motors, and other PM or switched/synchronous reluctance motors for pumping applications. Typical power ranges shall be up to 22kW in the short-term, with higher power levels expected in the future.

As part of the role, occasional travel shall be expected from time-to-time to key Xylem R&D sites located throughout Europe, UK, US, and India.  In order to be successful, you will need to demonstrate leadership in pursuit of technical solutions, have a hands-on approach to problem solving and be able to manage your work against time, budget and customer expectations.
