Senior Electrolyte Scientist

About the Role

Anthro Energy is developing advanced electrolytes to enable safer, higher-performance lithium-ion batteries. We are seeking a Senior Electrolyte Scientist to lead electrolyte-focused R&D, from formulation design through electrochemical validation, in direct support of Anthro’s product development efforts.

In this role, you will design and evaluate electrolyte systems, study their behavior in battery cells, and work closely with cell design and engineering teams to ensure electrolyte innovations translate into meaningful improvements in cell performance. Your work will play a critical role in moving ideas efficiently from the lab into validated battery cells.

• Design, develop, and optimize lithium-ion battery electrolyte formulations to improve battery cell performance, including long-term cyclability, high-temperature stability, and safety.
• Perform electrochemical characterization and battery cell testing to evaluate electrolyte performance, understand degradation mechanisms, and guide formulation improvements.
• Investigate electrolyte–electrode interactions and interphase formation, using electrochemical and analytical techniques to identify failure modes and stability limits.
• Generate high-quality, reproducible experimental data with clear documentation to support data-driven decision-making and ongoing product development.
• Collaborate closely with cell design and engineering teams to align electrolyte development with cell-level performance requirements.
• Support translation of lab-scale electrolyte formulations into scalable, manufacturable solutions as programs advance.
• Document technical findings and contribute to Anthro’s intellectual property portfolio through the invention of disclosures.

• MS or PhD in Materials Science, Chemical Engineering, or a related field, with 5+ years of relevant industrial experience for MS candidates or 2+ years for PhD candidates.
• Strong understanding of lithium-ion electrolyte chemistry, including lithium salts, solvents, additives, and their impact on cell performance and stability.
• Hands‑on experience with electrolyte characterizations, electrochemical testing, and battery cell evaluation, along with solid data analysis and interpretation skills.
• Familiarity with analytical techniques commonly used for electrolyte, interphase, and degradation analysis (e.g., NMR, GC-MS, ICP‑OES/MS, XPS, SEM).
• Demonstrated ability to independently plan and execute experiments, manage multiple priorities, and operate effectively in a fast‑moving R&D environment.

• PhD in Materials Science, Chemical Engineering, or a closely related field.
• Demonstrated experience developing electrolyte formulations across multiple cell chemistry platforms, with the ability to tailor electrolyte design to different cell products.
• Hands‑on experience developing advanced electrolyte systems, such as polymer electrolytes, gel electrolytes, ionic liquid–based electrolytes, and other next-generation electrolyte concepts.
• Strong understanding of electrolyte–electrode interfacial chemistry, including experience studying interphase formation, degradation mechanisms, and long-term cell stability.
• Comfort working in an early‑stage R&D environment with high ownership and evolving technical challenges.
• Competitive salary and equity compensation commensurate with experience. Expected salary range is $116,000 to $145,000.
• 15 Vacation Days, 10+ Holidays, Sick time off.
• Full medical, dental, and vision coverage for team members, 60% coverage for dependents.
• 401k with match.
• Paid parental leave with flexible return‑to‑work policy.
• Diverse and inclusive work environment.
