Job Description & How to Apply Below
You will act as a senior technical contributor within BGMOS, applying first‑principles device physics and advanced TCAD simulation to guide development from concept through to industrialisation. This is a role for a deep technical thinker who enjoys solving complex problems, collaborating across functions, and turning simulation insights into real‑world semiconductor technologies.
What you will doAs a Principal Device Engineer, you will lead the TCAD‑driven development and optimisation of Power Trench MOSFET technologies. You will explore new device architectures, analyse performance trade‑offs, and translate simulation outcomes into process and layout requirements. You will support technology roadmaps, contribute to feasibility studies, and troubleshoot device‑level issues across development and production. You will collaborate closely with Process Integration, Product Development, Design, Manufacturing and Foundry partners, acting as a technical anchor for early‑stage innovation.
Key responsibilities
Develop and optimise Power Trench MOSFET architectures using advanced TCAD simulation
Perform electrostatic, thermal and reliability‑relevant simulations to guide device decisions
Design and refine cell structures, termination schemes, and next‑generation device concepts
Support technology roadmaps with quantitative trade‑off and feasibility analysis
Translate simulation insights into process, layout and structural requirements
Conduct day‑to‑day TCAD simulations, documentation, silicon learning support (splits, DOE, calibration), and troubleshooting of device‑level issues
Engage in regular technical exchanges with Process Integration, Product Development, Design, Manufacturing and Foundry partners
Contribute to intellectual property generation and early‑stage concept definition
What you will deliver
High‑quality TCAD simulation outputs and device concept evaluations
Optimised device architectures and termination schemes
Quantitative trade‑off analyses supporting technology roadmap decisions
Clear technical documentation and communication of simulation insights
Contributions to silicon learning cycles and device‑level troubleshooting
Technical inputs that influence product development and industrialisation IP disclosures and innovation proposals
Strong cross‑functional collaboration across BGMOS and manufacturing partners
What you will need Essential requirementsMSc or PhD in Electrical Engineering, Physics, or a related field
Several years’ experience in device engineering and TCAD‑based technology development
Strong understanding of semiconductor device physics
Deep expertise with TCAD tools (e.g. Synopsys Sentaurus)
Experience with Power MOSFET device concepts, ideally trench‑based
Ability to analyse performance, reliability and manufacturability trade‑offs Strong analytical and problem‑solving mindset
Clear, structured technical communication skills
Ability to travel occasionally as required
Beneficial
PhD focused on power semiconductor devices
Industrial or foundry experience in Power MOSFET technology
Experience with process integration or layout‑driven device optimisation
Knowledge of high‑field effects, ruggedness (UIS) and reliability mechanisms
Understanding of foundry developments and process transfers
Proactive, innovative mindset with the ability to challenge assumptions
