Your dream is to work in a fast-growing tech startup? Watt & Well is what you are looking for.


We are experts in power electronics, designing and manufacturing power supplies and motor controllers. We provide equipment for 3 demanding industries: aerospace, e-mobility and Oil & Gas.


Technical innovation and performance are the foundation of our company. Our products are embedded in cutting-edge applications. We provide two critical rad-tolerant motor controllers for the future Ariane 6 launcher. Our 25kW modular power units are integrated in the latest generation of quick chargers deployed across Europe. Our high temperature motor controllers take places inside the tools of a worldwide player of the O&G services, 10km under the ground, at 175°C ambient temperature. 


We are a dynamic multicultural team, composed of 40 employees, based in Massy (Paris area, France), Pertuis (Aix-en-Provence area, France) and Houston (Texas, USA).


Our engineering team is composed of technicians, engineers and PhDs, experts in power electronics, digital control and software, control theory, industrialization and manufacturing. To sustain our growth, we are currently looking for high energy women and men.


We are looking for an intern in Improved Control Laws for EV Chargers in Massy (91), with the objective to be hired consecutively.


Integrated in the e-Mobility team, the intern will be in charge of control laws improvement of our current EV charger product line. The objective is to increase compatibility with newer smart grid applications including V2G (Vehicle-to-grid) while keeping a modular approach for increased power needs of future usage.
