Cathode Scientist - LFP CAM

Princeton NuEnergy (PNE) is an advanced materials manufacturing and technology company, with the most cost-effective and capital-efficient process for the production of battery‑grade cathode active material (CAM) for lithium‑ion batteries. Built on a proprietary, closed‑loop platform, PNE's high‑performing technologies span multiple high‑growth materials businesses, including Rejuvenation (Cathode‑to‑Cathode® direct recycling), Advanced Black Mass™ production, Upcycled® CAM, and more — strengthening the domestic battery supply chain and supporting U.S. energy independence and national security priorities.

As a Cathode Scientist, you will be mainly working on the development of cathode active materials in the lab‑scale setting, with a specific focus on LFP. The ideal candidate will have knowledge in electrochemistry, LIBs, and prior experience with conducting hands‑on experiments, CAM synthesis and process design, and analytical capabilities.

• Independently lead the planning, design, and execution of complex experimental programs for LFP/LMFP cathode material synthesis, regeneration, process optimization, and scale‑up activities, including defining technical objectives, developing experimental methodologies, and driving data‑informed technical decision‑making
• Lead the development and optimization of cathode active material (CAM) processes for both virgin and recycled feed stocks, with a focus on material performance, process reproducibility, and manufacturing scalability
• Drive process innovation and continuous improvement related to direct recycling, cathode rejuvenation, and next‑generation cathode manufacturing technologies using PNE’s proprietary platform
• Conduct and oversee electrochemical evaluations, including coin cell and pouch cell fabrication, cycling analysis, rate capability testing, and long‑term performance validation
• Perform advanced material characterization and data analysis using techniques such as SEM, TEM, XRD, ICP, particle size analysis, and other physical and chemical characterization methods
• Collaborate closely with process engineering and pilot production teams to transfer laboratory‑scale developments into scalable manufacturing operations and pilot‑line implementation
• Support technical engagements with customers, strategic partners, and external collaborators regarding cathode material performance, process capabilities, and commercialization initiatives
• Participating in grant applications and writing up proposals from time to time

• PhD degree in chemistry, electrochemistry, physics, chemical engineering, materials science, or a similar field
• 1+ years of experience from industry or national laboratories in synthesis, characterization, process engineering, or electrochemistry of lithium‑ion battery materials
• Knowledgeable and hands‑on in scientific experiments, tests, data collection protocols, and analytical laboratory equipment
• Excellent organizational skills and the ability to effectively communicate with internal teams and external collaborators
• Strong problem‑solver, analytical and critical mindset with the passion and curiosity for continuous improvement and environmental sustainability
• Comfortable with working in a dynamic and fast‑paced environment, while handling multiple tasks and meeting deadlines

• This is an on‑site position in Bordentown, NJ
• Able to work in the research lab environment and wear personal protective equipment, including a dust mask, respirator, safety shoes, gloves, and safety glasses/face shield
• Able to lift & carry 50 pounds
• Able to stand, walk, and use hands to operate objects, tools, or controls; reach with hands or arms; climb, balance, stoop, kneel, or crouch when necessary for job activity
