YOUR ROLE 

MEMS are key components in ST product portfolio which support a wide range of consolidated and emerging applications. 
Within them, infrared sensors are one of the most recent and innovative products on the market, posing new design and industrialization challenges. 

As a MEMS infrared sensor design engineer, the following tasks are expected:

• definition of specifications matching ST technology and manufacturing capabilities
• driving and cooperating with other development teams like manufacturing technology R&D, electronics design, characterizazion, reliability and/or suppliers
• analytical and/or numerical modelization of the physical systems describing the transducer
• mechanical and multiphysical simulations of components by Finite Element commercial softwares like ANSYS and Comsol Multiphysics or by custom-made tools
• definition and finalization of design solutions to reach required performances from feasibility to complete product qualification and volume production
• verification of the adherence of the design targets to the real performance by critical analysis of experimental results (supporting testing teams or measuring directly, if needed) 

YOUR SKILLS & EXPERIENCES

The ideal candidate should have:

• a Master degree in Engineering (Mechanical, Electronic, Physical, Mathematical,Civil, Material Science) or Physics
• 3+ years experience in MEMS design and/or mechanical, optical or thermal sensors/systems. Previous experience in infrared sensors design or development for presence detection or temperature sensing is highly appreciated. 
• Good knowledge of physics, in particular mechanics, thermodynamics, optics and electronics. 
• Good knowledge of spoken and written English
• Curiosity and willingness to learn
• Attitude to team working and problem solving
• Proactive and flexible approach to work

Previous experience with softwares like Ansys, Comsol, Zemax, MATLAB is welcome but not mandatory.
