Position Summary

Blue Current is seeking a hands-on Senior Process Engineer for developing formulation and coating processes for next generation separators used in Blue Current's solid-state batteries. The ideal candidate will have a background in formulation, coating and characterization in the battery or adjacent industry (fuel cell/ solar/ electronic materials, etc). Additional experience in electrochemistry of lithium-ion batteries is a bonus. The Senior Process Engineer will design and conduct experiments for prototyping and characterizing new separator formulations and architectures, and collaborate with the Cell Engineering and Advanced Manufacturing teams for qualifying through cell builds and scaling up to the pilot line.

This is a highly cross-functional, hands-on and fast-paced position with a team of scientists and engineers that have a shared passion to change the energy storage landscape.

Essential Functions & Responsibilities

* Develop and test new materials, formulation, mixing and coating processes for separators that enable safe, high energy density solid-state batteries.

* Characterize slurry and separator quality using rheological, mechanical, imaging and electrochemical techniques, and develop new characterization methods as needed.

* Evaluating novel separator compositions and architectures in solid state cells. Analyze test results to understand the impact of separator properties on cell performance.

* Partner with the Advanced Manufacturing team to transfer mixing and coating processes to manufacturing equipment.

* Clearly communicate complex results to cross-functional teams and senior leadership.

* Work with cross-functional teams ensuring high-quality, on-schedule execution of projects.

* Continuously survey and interpret literature on solid-state battery materials and architectures, integrating key insights into the company's technical strategies.

* Contribute to the company's IP portfolio by exploring novel materials, cell designs, and processing approaches that advance solid-state cell performance

* Support a strong safety culture by following and improving laboratory safety practices, demonstrating exemplary experimental techniques, and helping implement best-practice updates.
