Hiring Manager
Jessica Colbert
Responsibilities
Generate, design, and iterate on novel cathode active materials (CAMs) based on performance targets, mechanistic hypotheses, and experimental feedback
Lead hands-on synthesis, including parameter optimization towards phase purity, morphological control and scalability
Perform and interpret advanced characterization to correlate structural and chemical insights with electrochemical behavior
Design and execute electrochemical testing including CV, EIS, LSV, GITT, PITT, rate capability, and cycle life
Translate lab-scale success into repeatable, documented synthesis processes
Support pilot-scale efforts and provide clear recipes and specifications to manufacturing partners
Work closely with members across multiple teams within the R & D organization to resolve performance bottlenecks
Communicate findings clearly, including what worked, what didn’t, and why
Coordinate with external labs when specialized characterization is required
Qualification
Required
PhD in Materials Science, Chemistry, Electrochemistry, Chemical Engineering, or related fields
Industry experience is preferred, but exceptional postdocs, recent PhDs, or national-lab researchers with strong hands-on credentials are encouraged to apply
Deep understanding of cathode active materials and structure–property–performance relationships
Demonstrated hands-on experience in material synthesis and optimization
Strong command of electrochemical testing and data interpretation
Practical experience with XRD, SEM, XRF, and complementary characterization tools
Ability to move comfortably between fundamental science and applied engineering constraints
You ask why before you optimize how
You can zoom from atomic structure to pouch-cell behavior without getting lost
You document your work well enough that someone else can reproduce it months later
You care about scale-up realities, not just Nature-grade plots
