The Opportunity
Agratas is on a mission to redefine the energy landscape through cutting-edge battery cell innovation. We're looking for a highly driven and visionary
Principal Cell Scientist
to lead the advanced research and development of lithium-ion (Li-ion) prototype cells.
As a
subject-matter expert
, you will play a pivotal role in shaping next-generation Li-ion cell technologies, integrating advanced materials and components to achieve exceptional performance, safety, and commercial viability. This is a unique opportunity to work at the forefront of sustainable innovation in energy storage, helping us unlock the next wave of high-performance battery solutions for electric vehicles and beyond.
The Principal Cell Scientist will lead advanced research and strategic development of prototype (pre-A) cells for lithium-ion batteries, driving innovation and validation of state-of-the-art and next-generation technologies. This senior role involves not only understanding and integrating (and, in future, perhaps developing) high-performance cell materials and components, but also understanding and mitigating cell failure modes, guiding cross-functional R&D efforts and enabling optimisation of high-performance and cost-effective next-generation cell concepts.
Key Responsibility Areas
Strategic Technical Leadership
* Lead the exploration and integration of state-of-the-art and emerging cell materials (anode, cathode, electrolyte, separator) to deliver high-energy, long-life, and safe Li-ion cells.
* Identify and mitigate failure modes through deep diagnostic and forensic analysis of prototype cells, applying findings to inform production design.
Advanced Cell Understanding
* Design and lead robust experimental programs to evaluate electrochemical, mechanical, physical, and electrical performance of cells and components.
* Ensure high-quality integration and compatibility across all cell components.
Competitiveness & Commercialisation
* Work closely with commercial teams and suppliers to stay ahead of market trends.
* Shape IP strategy, evaluate freedom-to-operate (FTO), and validate technology roadmaps with a view toward mass production, cost-efficiency, and sustainability.
Next-Gen Innovation
* Drive the innovation of future Li-ion technologies, ensuring Agratas remains at the forefront of energy storage.
* Use structured roadmaps and multi-generational planning to develop solutions with long-term commercial impact.
Cross-Functional Leadership
* Lead and mentor a team of scientists and engineers, fostering a collaborative culture that thrives on technical excellence, innovation, and commercial focus.
* Collaborate with internal teams across Cell Design, Product and Process Engineering to bring innovative concepts to life.
Data-Driven Optimisation
* Leverage structured experimentation and advanced analytics to continuously improve cell design and performance.
Strategic Planning & Reporting
* Maintain clear documentation of R&D plans, milestones, and results, providing transparent updates to senior leadership.
Job Context
What You'll Bring
Knowledge, Skills & Experience
* Deep expertise in Li-ion cell design, integration, and component optimisation.
* Proficient in advanced testing and validation methods (electrochemical, forensic, diagnostic).
* Proven track record of driving innovation in cell technology with industrial application.
* Strong analytical, problem-solving, and strategic thinking skills.
* Excellent communication, stakeholder engagement, and cross-functional collaboration.
* Industrial awareness of the battery landscape, with a commitment to continuous learning.
Qualifications
* PhD (or equivalent experience) in Chemistry, Chemical Engineering, Materials Science, or a related field.
* Extensive industrial experience in lithium-ion cell development.
Leadership Attributes
* Demonstrated experience in leading multi-skilled technical teams.
* High emotional intelligence, with the ability to mentor, inspire, and influence.
* Organised and goal-oriented, with a strong sense of urgency and delivery focus.
