About this role

About the Role Captura is seeking an experienced and hands-on Lab Technician to join our growing startup at a pivotal early stage in our ion exchange polymer and membrane development. This is a unique opportunity to contribute directly to the development and scale-up of next-generation ion exchange membranes through hands-on laboratory work.

The ideal candidate will have 3–5 years of practical laboratory experience in organic synthesis, polymer chemistry, materials development, or a related field, with strong laboratory skills, attention to detail, and a commitment to safe and organized laboratory practices. The Lab Technician will play an important role in executing day-to-day experimental work, supporting polymer synthesis, operating and maintaining analytical instruments, and ensuring that the laboratory remains safe, clean, organized, and efficient.

Responsibilities Perform organic synthesis and polymerization experiments following established procedures and experimental instructions provided by research chemists - up to 5-liter size reactors and 5-gallon size processing containers. Carry out routine laboratory operations under supervision of research chemists - reagent preparation, weighing and transferring chemicals, solution preparation, reaction setup, workup, precipitation, filtration, washing, and solvent removal.

Monitor reaction parameters such as temperature, viscosity, and conversion to ensure optimal conditions for polymerizations. Maintain accurate and timely laboratory notebooks, sample records, and analytical data. Assist with operation and routine maintenance of laboratory instruments and characterization equipment - NMR, GPC, viscometer, etc.

Organize laboratory chemicals, solvents, consumables, glassware, and other supplies. Maintain high standards
