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 122 nationalities, present in 40 countries, and comprising over 49,000 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 Team
The Optical Product Packaging & Design team, based in Edinburgh and Singapore, is part of ST’s wider Imaging & Custom subgroup. The team designs and develops precision opto-mechanical assemblies incorporating ST silicon sensors to deliver advanced optical and photonic products.
The Role
As a Thermal-Mechanical Simulation Engineer, you will work closely with the R&D project team to develop products that meet performance, manufacturability, and cost objectives. Using advanced simulation tools, you will perform finite element analysis (FEA), computational fluid dynamics (CFD), and multiphysics studies to identify potential issues early in the development process and to recommend design improvements that enhance product performance and robustness.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
You will also use analysis tools to support failure investigation and root cause analysis. In this role, you will collaborate with package design engineers, optical engineers, substrate designers, and core team members to ensure that proposed improvements are properly verified and implemented.
This position requires regular interaction with stakeholders across multiple geographic locations. The successful candidate must be comfortable working across different time zones and travelling at short notice where required.
