This position is ideally suited to a practical, laboratory-focused chemist or engineer who enjoys experimental work, developing robust laboratory procedures, operating specialist equipment, solving technical challenges, and translating experimental observations into improved material performance. 

ESSENTIAL DUTIES AND RESPONSIBILITIES  

The essential duties and responsibilities of this position include, but are not limited to, the following: 

• Develop, execute, and optimize laboratory procedures for pigment crystallization, crystal engineering, finishing, and post-processing. 

• Investigate and optimize crystallization conditions to control crystal form, crystal habit, particle morphology, and particle size distribution. 

• Plan and perform laboratory experiments under the guidance of project scientists. 

• Operate, maintain, troubleshoot, and take ownership of laboratory pigment finishing equipment, including mills, filtration systems, washing equipment, dryers, and associated processing equipment. 

• Develop and optimize milling, filtration, purification, washing, and drying procedures to achieve target particle size, morphology, purity, and process consistency. 

• Characterize pigments using particle size analysis, microscopy, spectroscopy, X-ray diffraction (XRD), and other analytical techniques. 

• Identify impurities and correlate analytical results with pigment properties, crystallization behavior, and processing conditions. 

• Record, analyze, and interpret experimental data to improve laboratory procedures and pigment performance. 

• Maintain accurate laboratory notebooks, experimental records, and standard operating procedures. 

• Ensure laboratory equipment is maintained in good working order and that all work is carried out safely and in accordance with environmental, health, safety, and quality requirements. 

• Prepare and screen newly developed pigments in electrophoretic display formulations. 

• Evaluate pigment performance within the internal phase of electrophoretic display devices. 

• Correlate pigment chemistry, crystal structure, particle morphology, particle size distribution, surface properties, and purity with electro-optical performance. 

• Use characterization and device performance data to recommend improvements to crystallization, pigment finishing, and processing procedures. 

• Collaborate closely with formulation scientists, materials scientists, and device engineers to support the development of next-generation electrophoretic display materials. 
• Prepare clear technical reports and present experimental findings and recommendations to project teams.
