Mechanical Simulation Intern

At STMicroelectronics, we believe in the power of technology to drive innovation and make a positive impact on people, businesses, and society. As a global semiconductor company, our advanced technologies and chips form the hidden foundation of the world we live in today.

When you join ST, you will be part of a global business with more than 115 nationalities, present in 40 countries, and comprising over 50,000 diverse and dedicated creators and makers of technology around the world.

Developing technologies takes more than talent: it takes amazing people who understand collaboration and respect. People with passion and the desire to disrupt the status quo, drive innovation, and unlock their own potential.

Embark on a journey with us, where you can innovate for a future that we want to make smarter and greener, in a responsible and sustainable way. Our technology starts with you.

The Mechanical Simulation Intern will join the Module and Optics Research and Development team which is part of the wider ST Imaging Division.

The group, which has expertise in optical, mechanical, and electrical disciplines, are responsible for designing precision opto‑mechanical technologies, incorporating ST silicon sensors and optics to produce state‑of‑the‑art optical and photonics devices. The products, such as time‑of‑flight laser sensors, ambient light sensors, and cameras, are designed for the consumer, mobile, industrial and automotive markets.

The devices are designed and developed in cooperation with other ST groups around the world and in partnership with suppliers and subcontractors. With a strong design emphasis on cost and industrialisation for very high volume, ST sensors are developed using state of the art materials, components, and precision automated assembly processes.

The role in the mechanical simulation team will entail combining simulation with experimental measurements to analyse different semiconductor packages. The successful applicant will primarily work on developing new modelling techniques and helping to evaluate their efficacy for future applications. Potential research topics may include, homogenised material property application in Finite element analysis (FEA), transient thermal response of a system in package (SIP), parameterised stress analysis of package structures.

FEA and thermal computational fluid dynamics (CFD) are performed using ANSYS commercial tools, augmented by Python and Excel for experimental data signal filtering and post processing. Code development in Python will be part of the role.

The role provides an opportunity to collaborate with engineers across multi‑disciplinary teams, including mechanical designers, measurement analysts, and electrical systems engineers. The ideal candidate will have an analytical mindset with the confidence to take on challenging numerical tasks independently, as well as an inquisitive nature for open collaboration with other team members.

• 
  
• Working towards a Master’s degree in Mechanical Engineering.
  
• Ideally some experience in FEA, alternatively experience in using matrix methods for structural analysis.
  
• Candidate will have completed courses in; Solid mechanics with competence in analytical solutions, thermodynamics with good understanding of Fourier’s law of heat conduction, and material science of dielectrics (ceramics), metals, polymers.
  
• Proven experience in using Python or MatLab.
  
• CAD modelling experience ideal (any package).
