Electrolyte Development Scientist

At Ore Energy, we are on a mission to fundamentally expand the amount of energy society can reliably use, helping move civilization toward a more abundant energy future. We are doing this by developing long-duration, utility-scale iron-air batteries that provide safe, low-cost, multi-day energy storage for electricity grids and data centers. We are expanding our R&D and product capabilities and are looking for an Electrolyte Development Scientist to join our team in Amsterdam. In this role, you will lead the formulation, advanced characterization, and continuous optimization of our electrolyte chemistry to enhance the performance, lifetime, safety, and manufacturability of our iron-air energy storage technology. Operating at the intersection of electrochemistry, advanced materials science, and scalable manufacturing, you will combine fundamental formulation strategies with cutting-edge in situ and operando analytical diagnostics. You will develop deep insights into real-time electrolyte behavior, component interactivity, and cell degradation mechanisms. This is a high-impact, hands-on technical role for a curious and rigorous problem-solver who thrives in an active R&D scale-up environment where the technical playbook is still being written.

Formulation & Optimization: Develop, refine, and optimize high-performance electrolyte formulations specifically engineered for iron-air battery systems. Physical & Electrochemical Characterization: Lead comprehensive physical, chemical, and electrochemical characterization loops to evaluate composition, ionic conductivity, viscosity, transport dynamics, stability, and aging. In Situ & Operando Diagnostics: Design and deploy advanced in situ and operando characterization setups to track real-time electrolyte behavior, gas evolution, and degradation mechanisms during cell operation. Component Interactivity: Investigate complex chemical and electrochemical interactions between the liquid electrolyte, porous electrodes, separators, and internal cell materials. Structure-Performance Mapping: Correlate in situ analytical data directly with cell-level electrochemical performance metrics, overpotentials, and degradation pathways. Specifications & Quality Control: Define internal electrolyte specifications, standardized test protocols, chemical safety guidelines, and quality assurance requirements. Scale-Up & Supplier Integration: Support technology transfer to pilot manufacturing lines, establish supplier qualification standards, and drive raw material optimization. Cross-Functional Collaboration: Partner closely with cell development, materials, testing, mechanical design, and manufacturing teams to translate fundamental chemical insights into system-level improvements.

Education: PhD in Chemistry, Electrochemistry, Chemical Engineering, Materials Science, or a related field. Core Expertise: Demonstrated track record in electrolyte formulation and characterization for batteries, fuel cells, electrolyzers, or adjacent electrochemical systems. In Situ / Operando Mastery: Hands-on experience developing or applying in situ / operando characterization techniques (e.g., in situ Raman, synchrotron methods, operando gas analysis, ICP, chromatography, EIS, rheology, or microscopy). Chemical Understanding: Deep mastery of electrolyte chemistry, ion transport phenomena, interfacial behavior, electrochemical stability windows, and failure modes. Industry & System Background (Preferred): Experience with aqueous or alkaline electrolyte chemistries, metal-air battery systems, or long-duration energy storage (LDES) is a strong advantage. Advanced Methods (Preferred): Familiarity with custom in situ cell design, transport modeling/simulation, corrosion mitigation, additive chemistry, and process scale-up/supplier qualification. Analytical & Execution Mindset: Highly organized, data-driven, and proactive. You thrive on the lab floor directly handling experimental setups alongside multidisciplinary engineering teams. Communication: Flawless professional English. Exceptional technical communication skills with a collaborative, solution-oriented approach to problem-solving.

The Challenge We Are Solving Do you want to contribute to one of the most important challenges of our time: accelerating the energy transition? Are you excited by breakthrough energy storage technology with real-world impact? Would you like to be part of a mission-driven company where your work directly contributes to building the future of clean energy? Then we are looking for you. Ore Energy develops long-duration energy storage solutions to support a reliable, zero-carbon electricity system. Powering the Next Generation of Infrastructure The electricity grid is undergoing its most significant transformation in a century. As renewables become the cheapest source of new power, the challenge is no longer producing clean energy, it is making it reliably available when and where it is needed, regardless of when the sun shines or the wind blows. Our iron-air batteries are uniquely designed to store renewable energy over multi-day periods, allowing clean electricity to become a dependable, around-the-clock backbone of the grid while reducing reliance on fossil-fuel peaker plants and building a more resilient, fully decarbonized power system. This is a rare opportunity to join a company at the moment when technology readiness, customer traction, and market demand are converging. Ore Energy has already raised significant capital, built and tested its technology under real-world conditions, and is now moving toward large-scale commercial deployment. As we transition into this industrial implementation phase, we are building the team, systems, and capabilities required to scale our solution and help define how long-duration storage powers both the future grid and the next generation of industry and data infrastructure. Our Culture & Beliefs We believe impactful technology is built by talented people who are motivated by complex challenges, scientific rigour and strong execution. That is why we are looking for dedicated professionals who want to help shape a cleaner and more resilient energy future. At Ore Energy, we are committed to fostering an inclusive and diverse workplace where every individual has the opportunity to thrive. We believe that diversity of thought, background, and experience drives innovation and success. Are you unsure if you meet all the requirements? Please do apply, we’d love to hear from you!
