Position Summary: 

• The Membrane Engineer will play a key role in the design, development, and optimization of advanced membrane materials used in semiconductor filtration applications. This role involves hands‑on formulation, casting, and characterization of immersion‑cast membranes, development of novel membrane fabrication processes as well as collaboration with cross‑functional teams in R&D, manufacturing, marketing, and quality. The engineer will contribute to both early‑stage technology development and scale‑up activities that support new product introduction. 

Responsibilities: 

• Develop and optimize nonsolvent‑induced phase separation (NIPS) processes for producing immersion‑cast membranes.  

• Develop novel membranes through innovation in materials, membrane structures, and manufacturing processes, creating differentiated products that deliver breakthrough performance, scalability, and customer value. 

• Conduct laboratory‑scale and pilot scale trials and support manufacturing‑scale runs.  

• Analyze membrane performance using characterization tools such as porometry, SEM, mechanical testing, permeability/retention tests, and chemical compatibility evaluations.  

• Document experiments, create technical reports, and present findings to internal stakeholders.  

• Lead intellectual property generation efforts by identifying patentable innovations and contributing to patent applications, invention disclosures, and freedom-to-operate assessments. 

• Partner closely with operations and manufacturing teams to ensure robust process development, process optimization, and successful product launches. 

• Work with procurement, marketing, and product management to support cost, performance, and timeline objectives.  

• Troubleshoot material, process, or equipment issues related to membrane development.  

• Maintain safe laboratory practices, following all EH&S protocols.  

• Support customer interactions and technical discussions as needed. 

Qualifications and Preferred Skills: 

• Ph.D. in Chemical Engineering, Materials Science, Polymer Science, Chemistry, or a related field, with at least 5 years of research experience and a demonstrated track record of technical innovation, scientific leadership, and development of advanced membrane technologies from concept through commercialization  

• Genuine passion for scientific research, experimentation, and problem‑solving.  

• A strong can‑do attitude, with the ability to tackle challenges proactively and independently.  

• Deep expertise in membrane materials, membrane manufacturing processes, filtration science and separation technologies  

• Proven hands-on experience developing and evaluating novel membrane materials and processes, from laboratory-scale concepts through prototype validation. 

• Demonstrated record of innovation and creative problem solving in the field of membrane formation  

• Proven ability to lead cross-functional programs and influence stakeholders without direct authority.  

• Excellent communication, presentation, and customer-facing skills. 

Physical Requirements: 

• Ability to work in a laboratory setting for extended periods, including standing, walking, and performing hands-on experiments.  

• Ability to lift and handle laboratory materials, chemical containers, or equipment up to approximately 25–30 pounds.  

• Manual dexterity for operations such as membrane casting, sample preparation, and equipment setup.  

• Comfortable wearing appropriate personal protective equipment (PPE), including lab coats, gloves, safety glasses, and, when required, respirators.  

• Ability to work safely with chemicals, solvents, and laboratory tools following established safety procedures.  

• Visual acuity to accurately perform experimental work, observe membranes, and read instruments or displays.
