Position description :
The Team
The Optical Design Engineer will join the Module R&D Design Group, part of the wider Imaging Division, with expertise in optical, mechanical and electrical design. The Group design precision opto-mechanical technologies and assemblies, incorporating ST silicon sensors and optics to produce state-of-the-art high performance optical and photonics products.
Our module products primarily target the consumer market, with applications in mobile phones and portable equipment such as laptops and tablets. The products 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 modules are developed using state of the art materials, components, and precision automated assembly processes.
Wafer-scale diffractive optics has recently brought about new possibilities and performance in a myriad of applications. The Module R&D Design Group designs high performance diffractive optical elements, with manufacturing in ST’s own cutting-edge 300mm silicon wafer fab.

The Role
The primary role is the design of optical components, including VCSEL beam shaping optics and objective lenses for use in ToF modules (NIR and SWIR). It requires highly skilled and proficient use of simulation tools such as Zemax or ST proprietary tools to establish performance, assess sensitivity to manufacturing variations and estimate yield as well as more complex system level simulation using for example LightTools.
They will support Mechanical Designers in tolerance and thermal analysis, and optimise optical designs to accommodate and ease the assembly or module integration. Strong practical skills will be required for characterisation of optical components in dark room environment following laser safety standards and risk assessments. They will support the product level laser safety certification.
They will collaborate with engineers across multi-disciplinary teams from silicon architecture, sensor design, systems engineering and applications to ensure appropriate system-level approach to ST ToF module design.
The Optical Design Engineer will need in-depth technical collaboration with external partners to help drive development of new technology, and clear technical communication with key customers will be essential to co-develop custom designs.
The role offers an opportunity to assist in the development of optic design methodology, and the development of custom design and simulation tools for both refractive and diffractive lenses. It also offers involvement in the development of optical metasurface technology involving design activity, performance analysis, and development of design tools.
The candidate may also have the opportunity to lead design activity within the project team and coordinate the integration of optical elements into the mechanical design of the ToF module.

·       Post-Graduate Degree (PhD preferred) in Optics or Physics
·       Track record of design & modelling optical components and systems, with an in-depth understanding of physics, radiometry and photonics
·       LightTools for system optical design, Zemax or CodeV for tolerance/sensitivity analysis and yield estimation (Monte Carlo).
·       Knowledge of design for manufacture techniques, and a design process lead by assessment of risks through DFMEA
·       Familiar with the design of optics to perform illumination diffusing and flattening operations, including diffractive optical elements
·       Experience of optical design for low-cost high-volume manufacturing using injection moulded polymers or wafer scale process techniques
·       Extensive experience in setting-up and performing optical measurements in dark room environment, defining and following laser safety procedures. Strong proficiency in Matlab or Python.
Education level required : 5 – Master degree
