Position Overview
The Senior Cell Design Engineer will be a key team member in an aggressive product design, development and analysis effort to produce and commercialize next-generation electrode materials, cell design and analysis techniquesThe focus of this position will be cell design, development, analyzing and launching cell products along with APQP process. This individual will identify the requirement through analysis, design DOE to test new materials, oversee cell builds, evaluate the results and make decisions and recommendations for the next steps of the development


Primary responsibilities

  • Design, develop, validate and analyze lithium ion cell components, assemblies, specifications and the full suite of the Phase Gate Process.
  • Execute analysis of key requirement for application and test result
  • Evaluate emerging anode and cathode materials and electrolytes, electrodes and cell designs against A123 requirements for next generation product performance, safety, and cost
  • Improve cell performance, quality, and abuse tolerance, increase the yields and reduce cost via DOE and advanced experimentation techniques
  • Analyze and evaluate cell data to determine direct and interaction effects of the materials under evaluation and plan and execute root-cause analysis of failures and appropriate action incurred over course of development and launch.
  • Identify short and long term roadmap for achieving high performance and cost reduction goals for Li-Ion battery separators
  • Identify the safety mechanism and create plan and execute to improve safety based on knowledge and understanding mechanism, especially for the cell using oxide chemistry
  • Develop and create report, comprehensive technical specifications, DFMEA.
  • Provide engineering support to manufacturing teams in order to resolve manufacturing process issues.
  • Effectively communicate results to broader teams in the US and abroad.
  • Interface closely with R&D scientists to increase understanding of failure modes, performance and life expectancy of lithium-ion cells.
  • Assist with engineering-level test builds together with quality and operations personnel at manufacturing facilities.
  • Collaborate with Supplier Quality team in their communication with material suppliers, related to the development and validation of detailed material specifications for new materials, and the resolution of any quality issues
  • Understand and adhere to program timelines





Specific Skills/Abilities


  • The position requires a self-starting, highly organized individual capable of identifying opportunities and taking responsibility for project implementation.
