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 to work on digital system design in Massy (91), with the objective to be hired consecutively.


Integrated into the aerospace team, the intern will be in charge of studying an advanced fault tolerant synchronization scheme implemented on Ariane 6 in 3 hot redundant FPGA controller boards. This scheme ensures that the majority of 3 controller boards remains always synchronized even when one controller board fails.


Main objectives


*      Understand existing fault tolerant synchronization algorithms developed by NASA/CNRS/etc

*      Help justify the algorithmics used in the synchronization controller and participate in the Failure Mode and Effect Analysis

*      Simulate the current synchronization controller implementation

*      Test the fault tolerance of the 3 hot redundant synchronization controllers on actual hardware


Main missions


*      Bibliography: DPLL’s and fault tolerant controllers

*      VHDL simulation

*      Algorithm justification (using pseudo code)

*      Test on actual aerospace hardware with 3 FPGA-based synchronization controllers 




*      You are in the last year of engineering school or equivalent

*      Strong skills in digital system design and VHDL

*      Strong analytical and mathematics background

*      You are dynamic and curious

*      You are fond of technology

*      You can communicate in English and French
