Job description

Overview

In this role you translate feasibility-stage concepts into robust, scalable production methods for silicone- and acrylic-based ophthalmic materials. You will build mechanistic and data-driven understanding of material behavior, lead process development, and guide transfer to manufacturing while collaborating across Engineering, Manufacturing, Quality, Regulatory, and R&D. You will tackle variability, improve process robustness, and enable reliable high-quality production at scale. This position offers a opportunity to impact premium cataract surgery outcomes and advance implant technologies.

Responsibilities
  • Lead development activities from feasibility through process development and manufacturing transfer
  • Understand interactions between material properties, process conditions, tooling, and product performance
  • Design and execute studies to reduce variability and establish process understanding
  • Investigate sources of variation using root-cause analysis
  • Develop mechanistic models and data-driven hypotheses to guide improvements
  • Apply DOE and statistical analysis to identify key process drivers
  • Characterize curing, molding, handling, and processing of silicone- and acrylic-based materials
  • Evaluate material-process interactions for final product quality and manufacturability
  • Develop and document process parameters, controls, and methods for scale-up and transfer
  • Present findings and recommendations to teams and senior management
  • Support troubleshooting in development- and pilot-scale manufacturing processes
Key requirements
  • Strong understanding of polymeric materials, especially silicones, acrylics, hydrogels, or soft-materials
  • Experience with polymer processing, curing, molding, scale-up, or process development
  • Ability to link materials, processing, microstructure, and performance
  • Strong root-cause investigation and troubleshooting skills
  • Experience developing mechanistic understanding through experimentation
  • Proficiency in statistics, DOE, multivariate analysis, and process capability assessment
  • Ability to analyze large datasets and translate findings into improvements
  • Experience with materials characterization techniques (rheology, spectroscopy, thermal analysis, microscopy, mechanical testing)
  • Excellent communication and cross-functional collaboration
  • Strong problem-solving and analytical mindset
  • Data-driven decision making
  • Design of Experiments (DOE)
  • Statistical analysis
  • Mechanistic modeling
