This role supports the development of novel surface chemistry modifications for polymeric membranes.
About the role
This R&D Engineer II position joins the Membrane R&D team to support the development of novel surface chemistry modifications for polymeric membranes with target applications in liquid filtration and purification in semiconductor fabrication processes.
What you'll do
- Develop new formulation and chemical processes using DOE, statistical analysis, modeling, and AI tools.
- Conduct membrane characterization using techniques such as flow time measurement, bubble point testing, FTIR, UV-Vis, and ion exchange capacity.
- Interpret membrane characterization and analytical metrology data, including ICP-MS, LC-MS, GC-MS, and other analytical techniques.
- Assist with process optimization for roll-to-roll manufacturing processes.
- Prepare technical reports, presentations, laboratory documentation, and intellectual property disclosures.
- Support customer sample evaluations and participate in technical discussions to address application and performance requirements.
What you'll need
- Bachelor's degree in Chemical Engineering, Materials Science, Polymer Science, Chemistry, or a related technical discipline.
- 3+ years of experience in product development, process development, manufacturing engineering, materials development, or applied research.
- Experience designing and executing laboratory experiments, collecting data, and documenting results.
- Strong analytical and problem-solving skills with the ability to interpret experimental data and make data-driven recommendations.
- Experience preparing technical reports, presentations, and project documentation.
- Ability to work effectively in both laboratory and manufacturing environments.
- Demonstrated commitment to Environmental, Health & Safety (EHS) standards and safe laboratory practices.
Nice to have
- Experience with membrane technologies, surface modification processes, and membrane characterization techniques.
- Familiarity with Design of Experiments (DOE), statistical analysis, and data interpretation methods.
- Knowledge of Design Failure Mode and Effects Analysis (DFMEA), root cause analysis, and risk assessment methodologies.
- Experience supporting pilot-scale trials, process development, and manufacturing scale-up activities.
- Familiarity with stage-gate product development processes and technology commercialization.
- Knowledge of quality systems, including SOP development, ISO requirements, laboratory documentation, and audit preparation.
- Experience supporting laboratory operations, including equipment maintenance, calibration coordination, inventory management, and laboratory organization.
