** About the Role
** We are seeking a highly skilled and motivated Battery Scientist/Engineer to lead the development of next-generation semi-solid, quasi-solid, and all-solid-state batteries in pouch cell format. This role focuses on interfacial engineering, particularly involving metallic anodes, and requires deep expertise in both lithium and sodium battery chemistries.###
** Key Responsibilities
*** Design, develop, and optimize semi-solid, quasi-solid, and all-solid-state battery systems in pouch cell configurations
* Conduct in-depth interface analysis between solid electrolytes and metallic anodes (e.g., Li, Na), including interphase formation and stability
* Develop strategies to improve interfacial kinetics, reduce impedance, and enhance cycle life and safety
* Evaluate and optimize electrolyte formulations (polymer, hybrid, or inorganic) for compatibility with high-energy systems
* Lead metallic anode integration, including dendrite suppression and plating/stripping efficiency
* Design and execute electrochemical testing protocols (EIS, cycling, rate capability, etc.)
* Collaborate with materials scientists and engineering teams to scale from lab to prototype cells
* Analyze failure mechanisms and implement performance improvements
* Stay current with emerging technologies and contribute to IP and publications###
** Required Qualifications
*** PhD or Master’s degree in Materials Science, Electrochemistry, Chemical Engineering, or related field
* Proven experience working with
** lithium and/or sodium battery chemistries
*** Hands-on experience with
** solid-state, semi-solid, or quasi-solid battery systems
*** Strong understanding of
** interfaces in battery systems**, especially solid electrolyte–metal anode interactions
* Experience with
** pouch cell design, assembly, and testing
*** Proficiency in electrochemical characterization techniques (e.g., EIS, CV, galvanostatic cycling)
* Familiarity with advanced characterization tools (SEM, XPS, TEM, etc.) for interface analysis###
** Preferred Qualifications
*** Experience working with
** metallic lithium and/or sodium anodes
*** Knowledge of dendrite mitigation strategies and interfacial coatings
* Background in polymer electrolytes or hybrid solid electrolytes
* Experience scaling battery technologies from lab to pilot level
* Track record of patents or publications in advanced battery technologies###
** What We Offer
*** Opportunity to work on cutting-edge battery technologies
* Collaborative and innovation-driven environment
* Competitive compensation and benefits
* Career growth in a rapidly evolving field
