Job Description
The SES AI Department is seeking an Electrolyte Scientist to join our team dedicated to mobile energy storage.
Key Responsibilities
- Formulation and Materials Design Design and develop electrolyte formulations compatible with high energy density lithium-ion anodes and high nickel content NMC cathode cell chemistries to achieve a long cycle life safely. Design electrolyte systems to demonstrate improvements in safety performance, including dimensional stability during battery cycling and storage. Provide technical assessment on existing electrolyte systems, additives, and lithium salts in high energy, high-capacity rechargeable lithium-ion cells.
- Electrochemical Characterization and Analysis Fully characterize coin and pouch cell performance using new materials and formulations. Utilize electrochemical testing and analytical techniques to understand reaction mechanisms, failure modes, and potential benefits of new formulations. Demonstrate the ability to use fundamental physical chemistry concepts and experimental techniques to provide promising electrolyte formulation strategies.
- Project Management, Communication, and Leadership Ability to independently plan, execute, manage, and communicate progress on projects. Support product development as required for the prototype-manufacturing team. Process Optimization: Design and implement streamlined testing metrics (e.g., Design of Experiments - DoE) to significantly shorten the R&D learning and development cycle. Communication & Insight: Effectively communicate new concepts, findings, and project updates to the team, drawing actionable insights from discussions. Technical Leadership: Serve as a technical mentor and leader to junior staff, guiding experimental design and professional development. Knowledge Integration: Actively integrate and synthesize existing in-house knowledge with new discoveries to accelerate development and problem-solving. IP Development: Proactively contribute to the company's intellectual property portfolio through invention disclosures and patent applications.
Requirements
- Advanced Degree: Doctorate (Ph.D.) in Chemistry, Chemical Engineering, or a related field, with 3+ years of post-PhD industrial experience.
- Diverse Formulation: Experience in formulation development beyond liquid electrolytes, including exposure to polymer electrolytes, ionic liquids, and/or solid-state electrolytes.
- Large Format Experience: Direct experience working with and characterizing large format cells (e.g., prismatic or cylindrical).
- Software/Modeling: Experience with computational chemistry or battery modeling tools.
- Industry Alignment: Demonstrated passion for and experience in the mobile energy or automotive space.
- The salary range for this position as required under applicable pay transparency laws.
- Salary Range
- $130,000
- —
- $170,000 USD
Benefits & Perks
- A highly competitive salary and robust benefits package, including comprehensive health coverage and an attractive equity/stock options program within our NYSE-listed company.
- The opportunity to contribute directly to a meaningful scientific project—accelerating the global energy transition—with a clear and broad public impact.
- Work in a dynamic, collaborative, and innovative environment at the intersection of AI and material science, driving the next generation of battery technology.
- Significant opportunities for professional growth and career development as you work alongside leading experts in AI, R&D, and engineering.
- Access to state-of-the-art facilities and proprietary technologies are used to discover and deploy AI-enhanced battery solutions.
