Natron Energy seeks a battery cell scientist to lead ongoing battery cell research projects. Natron Energy’s ability to produce batteries that perform reliably across a variety of customer use cases requires a deep fundamental understanding of the unique Prussian blue analogue cell chemistry and its failure mechanisms. The battery cell scientist will work closely with a small team, employing a rigorous fundamental scientific research approach, to continually improve upon the fundamental understanding of the Natron Energy batteries’ physics of failure. They will formulate and execute materials-level, component-level and cell-level experiments with the objective of deepening Natron Energy’s understanding of battery cell component structure property relationships.
The battery cell scientist will be responsible for independently driving cell research projects from the generation of new ideas to experimental execution, data analysis and final reporting. They will assist in converting experimental findings to specifications that will improve Natron Energy’s battery quality and reliability as the technology scales up to high-volume manufacturing. They will work on cross-disciplinary teams to solve complex problems and implement robust solutions. A qualified candidate will have a solid foundation in chemistry, materials science, or a related field with ample hands-on lab experience. They are detail-oriented, self-motivated, a strong communicator, and have the flexibility to continuously self-educate.
