Position Summary:

• TheMembraneEngineer will play a key role in the design, development, and optimization of advanced membrane materials used in semiconductorfiltrationapplications. This role involves handson formulation, casting, and characterization of immersioncast membranes,development of novel membrane fabrication processesas well as collaboration with crossfunctional teams in R&D, manufacturing, marketing, and quality. The engineer will contribute to both earlystage technology development and scaleup activities that support new product introduction.

Responsibilities:

• Develop and optimizenonsolventinduced phase separation (NIPS)processes for producing immersioncast membranes.

• Developnovel membranesthrough innovation in materials, membrane structures, and manufacturing processes, creating differentiated products that deliver breakthrough performance, scalability, and customer value.

• Conduct laboratoryscaleand pilot scaletrials and support manufacturingscale runs.

• Analyze membrane performance using characterization tools such asporometry, 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 problemsolving.

• A strong cando attitude, with the ability to tackle challenges proactively and independently.

• Deep expertise in membrane materials, membrane manufacturing processes, filtration scienceandseparation technologies

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

• Demonstrated record ofinnovation andcreativeproblem solvingin 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 approximately25 30 pounds.

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

• Comfortable wearing appropriatepersonal 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.
