This is a unique opportunity to support quality control, membrane development, laboratory, and pilot scale up activities. The ideal candidate will have prior experience in polymers, material science, chemistry, chemical engineering, or a related technical field who enjoys working in the lab, understands technical processes, and can translate experimental results into clear documentation and actionable process improvements.\nThe successful candidate will contribute towards catalyst and membrane development including formulation, development, testing, characterization, and QC evaluation while maintaining strong laboratory organization, record keeping, and safe work practices. This position requires being comfortable working with chemicals, laboratory equipment, process materials, and appropriate personal protective equipment (PPE). They will take full ownership of critical projects in a fast-paced setting, playing a key role in preparing, executing and documenting experiments to evaluate membranes, and scale up while driving continuous improvements in both process performance and safety.\nResponsibilities \nDaily Laboratory Responsibilities \nExecute hands-on laboratory research and development activities focused on membrane casting, and process optimization for advancing Ion exchange membranes.\nExecute polymer production activities including synthesis of polymer, including polymer purification, washing and drying and polymer solution preparation to meet the target specifications at lab scale leading to pilot scale quantities.\nDesign, execute, and document experimental protocols to evaluate polymer synthesis, and membrane casting tasks, to meet the product needs.\nGenerate, collect, compile, analyze, interpret, and summarize experimental and process data utilizing statistical analysis tools and design of experiment (DOE) methodologies to support product development, root cause analysis, process validation, and continuous improvement initiatives.\nQuality control and Testing \nPerform quality control (QC) and quality assurance (QA) testing of polymer solutions, membranes, and experimental lots using established analytical test methods, statistical process controls, and defined acceptance specifications.\nCollaborate in development and optimization of QC methods, inspection procedures, testing protocols, and process controls for polymers, casting solutions, membrane materials and related products.\nMonitor for process deviations, material issues, equipment concerns, or quality trends and communicate findings effectively to engineering, quality, and operations teams.\nLaboratory operations and compliance, safety and management\nOperate, calibrate, and maintain laboratory equipment used for polymer synthesis, membrane casting, chemical processing, material characterization and performance evaluation.\nMaintain accurate and GMP/GLP compliant laboratory documentation, including batch records, test records, standard operating procedures (SOPs), work instructions, and technical reports.\nComfortable working in the laboratory environment using solvents, chemicals and polymers adhering to established safety protocols and best practices.\nAdhere to all EHS requirements, chemical hygiene plans, and Personal Protective Equipment (PPE) requirements and safe handling procedures for hazardous chemicals, solvents, polymers, catalysts, laboratory equipment, and compressed gases.\nMaintain a safe, clean, and organized laboratory environment, including proper material labeling, storage, inventory management, waste disposal and handling, and housekeeping practices.\nQualifications\nBachelor’s degree in chemical engineering, material science, polymer engineering, chemistry or related field.\nPrior laboratory experience in quality control, analytical testing, materials testing, membrane development, coatings, membrane casting, chemical formulations, or related technical operations.\nExperience executing QC test methods, maintaining accurate laboratory records, following SOPs, documenting deviations, and working within structured quality or regulated laboratory practices is highly desirable.\nHands-on experience with analytical and characterization tools such as viscosity measurement, pH, conductivity, tensile testing, dimensional inspection, visual inspection, or other material and QC testing methods.\nExperience with analytical and characterization tools such as SEM, viscosity measurement, pH, conductivity, tensile testing or other material testing methods, and QC processes.\nProficient in Microsoft suite, statistical tools, design of experiments (DOE), root cause analysis, process troubleshooting and continuous improvement projects.\nExcellent leadership, communication, and organizational skills.\nDemonstrated experience working with hazardous chemicals and implementing safety protocols.\nAbility to collaborate cross-functionally and closely support with R&D.\nStrong organizational skills with ability to manage multiple samples, experiments, records and priorities in structured manner.\nComfortable working hands-on in a laboratory setting while wearing required PPE, including safety glasses, gloves, lab coat, safety shoes, and other task specific protection.\nAbility to communicate technical observations, data summaries, and process concerns clearly to cross-functional teams.\nCore Competencies\nHands on laboratory execution and attention to experimental detail.\nStrong documentation discipline and data integrity.\nTechnical curiosity and willingness to understand the full process from raw materials through finished membrane performance.\nQuality focused thinking with ability to identify trends, deviations and opportunities for improvement.\nGood organization, planning, ownership and management skills to conduct experiments and testing in the laboratory.\nAbility to work independently while also collaborating with production, R&D, testing and safety teams.\nCommitment to safe laboratory practices, PPE compliance, and proper chemical handling and storage.\nFeatured Benefits\nCompensation\nThe approximate salary range for this role is $75,000-$95,000. Actual compensation depends on factors unique to each candidate, including geographic location, education, experience, qualifications, and job-related skills. It is not typical for someone to be hired above the midpoint of the range.
