Mechatronics Technician

Within the Instrumentation Services and Development Division (ISDD), you will join the Mechanical Engineering Group, comprising 40 engineers and technicians in charge of the development, design, construction and testing of new scientific instruments for the ESRF particle accelerator complex and experimental stations (beamlines).

In the dedicated mechatronics lab and on the beamlines, you will contribute to the installation, start up and testing of advanced high-precision positioning devices integrating actuators, ultra-high precision displacement sensors, real-time active feedback control systems and optical systems. You will work in close relation with mechanical, control, electronics, optical and software engineers.

Your main duties and responsibilities will be the following:

Test bench preparation:

• Acquisition and control: Use of controllers to acquire sensor signals, and programme automated tests using command interfaces;
• Signal commissioning and analysis: use of oscilloscopes and multi-metres for rapid debugging of technical issues;
• Optics: assembly, alignment and testing of standard optical components (interferometers, encoders etc.) and custom optical systems (microscopes, sensors, spectroscopy probes etc.). Set up and perform tests for optical system development or acceptance tests;
• Mechanics: assembly of test set-ups;
• Electronics: cables (specification/order/testing), implementation and configuration of electronic systems;
• Participate in the development phase of new instrumentation.

Measurements and analysis:

• Measurements with diverse tools and their specific software: dial gauges, micrometres, interferometres, autocollimators...;
• Follow-up and/or perform acceptance tests (factory or site acceptance tests);
• Use computing tools for time-based or frequency analysis;
• Advise about improvements to implement on systems;
• Write up reports.
