Cell Engineer

Cell Engineer

Position Scope

The Cell Design Engineer will be a key team member, producing next generation cells for high energy and high power applications. The successful applicant will develop, produce and commercialize innovative cell designs based on proprietary materials. The responsibilities of this position will cover cell design, development, analysis, and support for product launch. Specific activities will include creation of new cell designs, implementing designs of experiments (DOEs) for new cells and materials, overseeing cell builds, and evaluating cell test results.

This individual will utilize a strong theoretical and working knowledge of cathode, anode, electrolyte, and separator materials, as well as how these components work together to make a successful cell. It is expected that the candidate will also be familiar with testing and analysis techniques used to characterize battery devices and materials. Additionally, this candidate will need to be comfortable working within an industrial product development environment, including experience with or ability to learn formal product development tools (such as APQP).

The Cell Design Engineer will be based in our Woburn, MA location and report to Chief Technology Officer.

Responsibilities

• Design, development, validation, and analysis of Li-Metal components, assemblies, and specifications.
• Selection, characterization, and validation of Li-Metal cell materials and components, (active materials, additives, electrodes, separators, electrolytes, etc.)
• Electrode optimization including formulation, coat weight, density, and porosity.
• Statistical data analysis for electrode & cell quality.
• Plan, develop and execute Design of Experiments for fabrication and testing of lithium-ion cells.
• Analyze and evaluate chemical and electrochemical data to determine direct and interaction effects of the materials under evaluation and execute root-cause analysis of failures and appropriate action incurred over course of development and launch.
• Propose cell and/or electrolyte design changes to optimize battery performance for different applications.
• Provide engineering support to cell manufacturing teams in order to resolve manufacturing process issues.
• Work with external suppliers, vendors, national labs, and academic institutions.
• Develop and create comprehensive technical specifications, drawing, and DFMEA.
