- Design and develop wafer level packaging solutions, 2D/2.5D/3D, for advanced silicon photonics platforms
- Create and optimise metallisation layouts (e.g. UBM, RDL, Solder, TSVs) to meet electrical, mechanical and manufacturing requirements.
- Define and engineer package mechanical features, including die interfaces, alignment structures, stress management and assembly tolerances.
- Perform thermal modelling and analysis to optimise heat dissipation, thermal resistance and package reliability across operating conditions.
- Develop and execute package validation plans, including optical performance, mechanical, thermal, and reliability testing of finished hardware, analysing results and driving design improvements.
- Collaborate with process, assembly and foundry partners to ensure package designs are compatible with wafer level fabrication, bonding and high-volume manufacturing processes.
- Conduct package verification through simulation, design reviews and failure analysis, driving continuous improvement in performance, manufacturability and yield.
- Support the integration of photonic devices by considering package impacts on optical alignment, optical coupling efficiency and overall system performance, working closely with photonic design teams.
