Posted on Thursday, March 30, 2023
Natron seeks a battery engineer to assist ongoing research and reliability experiments. The battery engineer will work closely with a small team to continually improve upon the quality and reliability of Natron’s industrial power solutions. Natron’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 technology. Therefore, the engineer in this role will implement a rigorous fundamental scientific research approach to define and verify battery cell specifications. They will play a critical role in enabling the scale-up of a novel battery chemistry to high-volume production.
The battery engineer in this role will assist in the formulation and execution of materials-level and cell-level experiments with the over-arching goals of improving and minimizing variations in overall cell performance. They will assist in converting experimental findings to specifications that will improve Natron’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. They are detail-oriented, self-motivated, a strong communicator and have the flexibility to continuously self-educate.
