Assystem Technologies is an international engineering and innovation consulting group, which assists major industrialists in the various stages of their projects. I realized my thesis in Toulouse, France, with the "automatic test" team. They mainly work for the customer Airbus on the support and validation of a sequencer, performing test procedures on aeronautical systems test benches. During my time in Assystem Technologies, the aim of my work was to propose innovative solutions for the Assystem Technologies sequencer technology, in order to implement a prototype which can be shown as a demonstrator to the company customers, detaching from the current specific Airbus implementation.
