About the job Materials Engineer - Chemist
Materials Engineer - ChemistCastelion is seeking a highly motivated chemist to support development and scale-up of a proprietary wet chemistry process that is central to production of next-generation aerospace materials. This role is ideal for an individual interested in reaction development, process optimization, and translating laboratory-scale chemistry into robust manufacturing processes.
The role combines hands-on laboratory chemistry with analytical process development responsibilities. The chemist will execute and optimize multi-step chemical syntheses, characterize reaction products, develop standardized operating procedures, and support the transition of the process from laboratory-scale production to increasingly larger manufacturing systems.
Responsibilities- Execute and monitor multi-step wet chemistry synthesis processes to support development and production activities.
- Design and perform experiments to optimize reaction conditions, yields, purity, and process repeatability using structured experimental methodologies.
- Characterize reaction intermediates and final products using standard analytical laboratory techniques.
- Collect, organize, and analyze process and analytical data to support process optimization and manufacturing readiness.
- Develop and maintain process documentation, work instructions, batch records, and standardized operating procedures.
- Troubleshoot reaction, purification, and process issues in a fast-paced development environment.
- Support scale-up activities by evaluating reaction performance across increasing batch sizes and implementing process improvements to enable future production capacity.
Basic Qualifications- Bachelor's or Master's degree in Chemistry, Chemical Engineering, Polymer Chemistry, Organic Chemistry, or a related field.
- 1+ years of wet chemistry synthesis experience
Preferred Skills and Experience- Experience with wet chemistry processing, hazardous chemical handling, and laboratory-scale synthesis.
- Familiarity with standard analytical characterization techniques (e.g., GC, GC-MS FTIR, NMR, Chromatography, DSC, TGA, or equivalent).
- Strong experimental design, data analysis, and technical documentation skills.
- Ability to work independently in a hands-on laboratory environment.
Benefits And Perks- Employee Equity: Meaningful equity for all full-time employees - share value has increased 150x in three years
