About the Role

Within the Engineering Design & Development department, you will be responsible for evaluating the current predictive capabilities of lens simulation studies in PC/PMMA, including filling, post-deformation, and optical properties. You will also participate in defining optimization strategies, related to calculation models, methodologies, material characterization, software tools, process parameters, and multi-shot approaches.

 

Start date: February 2026 
Duration: Ideally 6 months 

 

Your Main Responsibilities

  • Conduct a literature review on lens injection and simulation

  • Correlate simulation results with experimental tests

  • Benchmark different software tools (Moldflow, Moldex, …)

  • Contribute to optimizing the prediction of post-molding deformations, internal stresses, and optical properties

 

About You

  • You are pursuing a Master’s degree (Bac +5) in Materials Engineering, Plastics, Injection Process Simulation, or Mechanical Engineering
