Principal​/Lead Scientist – Cathode Development; Lithium-Sulfur Batteries

We are partnering with a pioneering battery technology company developing next-generation lithium-sulfur battery systems, with a strong focus on high-performance cathode architectures and pouch cell development. The organization is focused on translating advanced chemistry into scalable, industrially relevant battery solutions.

This is a unique opportunity for a Principal/Lead Scientist to play a central technical role in shaping cathode development strategy, influencing key cell architecture decisions, and advancing lithium-sulfur technology from experimental validation through industrial scale-up.

In this role, you will contribute hands-on to cathode materials development and pouch cell fabrication, electrochemical performance evaluation, and materials characterization, while working closely withcross-functional technical and engineering teams. Your work will directly support the experimental validation, scale-up readiness, and long-term reliability of the company’s core lithium-sulfur battery technology.

Why Join?

• High Technical Impact: Contribute directly to the advancement of next-generation lithium-sulfur battery technology.
• Scientific Ownership: Take ownership of cathode concepts and their translation into full pouch cell performance.
• Scale-Up Focus: Work closely with cross-functional teams to address real-world challenges in cell assembly, durability, and consistency.

Key Responsibilities:

• Design, develop, and optimize cathode materials and architectures for lithium-sulfur battery systems.
• Lead and support pouch cell fabrication, assembly, and performance evaluation activities.
• Conduct and interpret advanced electrochemical testing, including EIS, CV, rate capability, and cycling performance.
• Investigate degradation mechanisms and failure modes using SEM, XPS, and post-mortem analysis.
• Collaborate with internal teams on electrode processing steps such as coating, drying, calendering, and cell assembly.
• Support continuous improvement of cathode formulation, sulfur utilization, and overall cell performance.
• Contribute to technical documentation, patent filings, and scientific publications.

What We’re Looking For:

• PhD in Materials Science, Chemistry, Electrochemistry, Chemical Engineering, or a closely related field.
• Minimum 5 years of hands-on experience specifically in lithium-sulfur battery R&D, with clear depth in cathode development and pouch cell systems.
• Strong background in electrochemical characterization and materials analysis (e.g., EIS, CV, SEM, XPS).
• Ability to work independently on complex experimental challenges while collaborating effectively in multidisciplinary technical teams.
• Proven contributions to patents, publications, or proprietary technology development within battery-related research.

What’s on Offer:

• Compensation aligned with senior technical expertise.
• Opportunity to work on core lithium-sulfur battery technology with direct industrial relevance.
• Collaborative, science-driven environment with a strong focus on innovation and technical excellence.
• Long-term growth opportunities within a highly specialized battery technology organization.
