SPEOS Optical and Thermal Simulation Engineer

Role Overview

Motherson Technology Services Limited is looking for an Optical and Thermal Simulation Engineer to strengthen the design and optimization of optical and heat-management systems. The role focuses on simulation work using Ansys SPEOS and Siemens FloEFD, with applications in automotive lighting, displays, sensors, and thermal systems. A major emphasis will be on projection and headlamp-related development.

What You Will Do

• Run optical studies in Ansys SPEOS to measure and improve lighting performance, including decoupling structures, stray light behavior, and photometric characteristics.
• Carry out thermal simulations for optical and electronic assemblies using Siemens FloEFD to study heat transfer, thermal deformation, and the influence of materials.
• Refine illumination and imaging designs by tuning light guides, extraction structures, reflectors, lenses, and diffusers.
• Check designs against applicable regulations and customer-driven technical requirements.
• Work closely with mechanical, electrical, and software teams to embed optical solutions into broader product systems.
• Review simulation outputs and convert findings into practical design recommendations.
• Support prototype development and physical validation of optical solutions.
• Prepare clear technical reports and documentation covering methods, assumptions, and results.

Required Background

• A Bachelor’s or Master’s degree in Optical Engineering, Physics, Mechanical Engineering, or a related discipline.
• Hands-on experience using Ansys SPEOS for optical simulation.
• Experience with Siemens FloEFD for thermal simulation of electronic/optical systems.
• Understanding of optical fundamentals such as light propagation, reflection, refraction, and scattering.
• Knowledge of thermal control methods used in optical and electronic assemblies.
• Exposure to additional simulation platforms such as Ansys Mechanical, Fluent, Zemax, TracePro, or COMSOL will be an advantage.
• Strong grasp of how material properties affect optical and thermal behavior.
• Good analytical thinking, troubleshooting ability, and communication skills.
• Prior experience with interior lighting parts used in vehicles.

Preferred Experience

• Background in automotive lighting, AR/VR, or LiDAR.
• Experience correlating simulation models with experimental test data.
• Familiarity with optical measurement methods and related instruments.
