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.
  • 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

 

Specific skills/abilities

  • An ability to communicate new concepts and draw insight from discussions with coworkers;
  • Expertise and hands-on experience in high purity chemicals and impacts on device performance and manufacturing;
  • Knowledge of common lithium-ion anode and electrolyte systems; including common lithium salt, solvents, and additives, and their role
  • Demonstrable track record of learning new technologies quickly and using your skillset to have a tangible impact in a short time frame;
  • Ability to onboard and integrate existing in-house knowledge with new discoveries and challenges being tackled in developing electrolyte materials for high energy rechargeable lithium metal cells;
  • Ability to identify and execute testing metrics to shorten the cycle of learning;
  • A technical leader with the ability to positively influence peers and bring the team together;
  • Track record of intellectual property creation;
  • Experience in mixture DOE;
  • Has worked with moisture sensitive materials in the glovebox or dry room.
  • Nice to have: Proficiency in cell assembly, cell test, and data analysis

 

Qualifications

  • MS in Chemistry, Materials Engineering, Chemical Engineering, or related field.
  • At least three years of industrial experience in Li-Ion or related technologies.
  • Demonstrated expertise and success in design and development of components and assemblies for lithium-ion battery.
  • Competency in the DFMEA process.
  • Working experience with Quality & Reliability disciplines (APQP, 8D, etc.)
  • Experience in design and development of batteries/cells.
  • Familiarity with statistical analysis and Design of Experiments preferred.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in SES’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.


Voluntary Self-Identification of Disability

Form CC-305

OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
