About the company:

Ore Energy is developing the next generation of long-duration energy storage to enable a fully renewable power system. Our iron-air battery technology stores electricity for up to 100 hours, making it possible to keep grids running through multi-day periods of low wind and sun.

Unlike conventional batteries, our systems use abundant, non-toxic materials: iron, air, and water. This makes them safe, cost-effective, and scalable without relying on scarce minerals or fragile supply chains. When charging, the battery converts rust into metallic iron. When discharging, it reverses the reaction, consuming oxygen and producing rust again. This simple, proven chemistry has the potential to deliver energy at a fraction of the cost of other storage technologies.

Founded at TU Delft in the Netherlands, Ore Energy is focused on real-world deployment. In 2025, we connected the world's first iron-air battery to the grid in Delft. This milestone demonstrated that multi-day storage can be integrated directly into modern energy systems.

As countries expand renewable generation, the challenge of balancing supply and demand is becoming urgent. We believe long-duration storage is a critical part of the solution and that it must be safe, sustainable, and affordable at scale.

Ore Energy’s mission is clear: to store renewable energy anywhere, for as long as needed, using materials that are available to everyone. By combining deep electrochemistry expertise with practical engineering, we are turning one of Earth’s most abundant resources into a cornerstone of the clean energy transition.

The role

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.

Key responsibilities

  • 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.

Your profile

  • 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.
