What we Need:
The SES AI Hermes team is seeking an exceptional Cell Product Design Engineer to serve as an expert in pouch-type Li-ion battery design and NPI (New Product Introduction) processes. This role is critical for integrating R&D innovations, testing rigor, and manufacturing feasibility to ensure the delivery of safe, high-performing battery products. As the Lead Cell Product Design Engineer, you will manage the technical design and lifecycle of our advanced battery cells, ensuring successful transition to commercialization.
Essential Duties and Responsibilities:
- Cell Design & Lifecycle Management
- Lead the technical design of pouch-type Li-ion battery cells, focusing on applications for EV (Electric Vehicle) and ESS/UAM (Energy Storage Systems/Urban Air Mobility).
- Manage the complete battery product lifecycle, from initial concept and prototype development through validation and successful mass production scale-up.
- Design and validate NCM-based pouch cells and contribute to the delivery of commercial platforms (e.g., scooters, e-bikes, EVs).
- Cross-Functional & Quality Assurance
- Drive the NPI process, ensuring robust design practices are followed from the earliest stages.
- Implement and utilize key quality and safety assurance methodologies, including DFMEA (Design Failure Mode and Effects Analysis) and DVP&R (Design Verification Plan and Report).
- Work cross-functionally with R&D, testing, and manufacturing teams to capture design inputs, define product specifications, and ensure alignment between technical feasibility, safety, and customer performance requirements.
Education and/or Experience:
- Education: M.S. in Materials Science, Chemical Engineering, or a closely related engineering field. A B.S. in Inorganic Nonmetallic Materials Engineering or equivalent is required.
- Core Expertise: Deep, hands-on expertise in pouch-type Li-ion battery cell design and NCM-based cell validation.
- Product Lifecycle: Proven experience managing the full battery product lifecycle, including NPI (New Product Introduction) from prototype to mass production.
- Quality Systems: Direct experience implementing quality methodologies such as DFMEA and DVP&R within a manufacturing or R&D environment.
- Domain Focus: Strong foundational knowledge of Battery Chemistry and its application to high-performance cell design for EV and ESS/UAM.
Preferred Qualifications:
- Industry Background: Previous experience at EV battery manufacturers or high-volume cell production companies.
- Application Diversity: Experience designing cells for various commercial platforms beyond EV (e.g., stationary storage, micromobility).
- Leadership: Experience leading cross-functional design efforts and serving as a key interface between R&D and manufacturing.
