At Ore Energy, we are developing long-duration, utility-scale iron-air batteries to provide safe, low-cost, multi-day energy storage. Having raised over €60 million from leading climate and energy investors and demonstrated our technology under real-world utility conditions, we are now entering our next phase of growth: financing our industrial scale-up, developing our giga-factory, and deploying multi-day storage across grid-scale markets.
We are expanding our industrialization capabilities and are looking for a Senior Process Engineer with experience in powder metallurgy technologies to join our Factory Engineering team in Amsterdam. Operating as a technical focal point at the intersection of process design, equipment procurement and high-volume production scaling, you will play a pivotal role in translating complex product requirements into stable, efficient and safe manufacturing solutions.
Focused on powder metallurgy technologies such as powder mixing and sintering, you will take full technical ownership of a set of core manufacturing process steps, bridging the gap between R&D and mass production. You will collaborate closely with cross-functional stakeholders and international equipment suppliers to define process parameters, establish engineering methodologies and lead vendor fulfillment through installation and commissioning. As a senior member of the team, you will lead by example, mentoring junior engineers and driving a culture of best practices.
This is a hands-on, execution-heavy role in a fast-paced, early factory design environment that requires a structured problem solver comfortable navigating ambiguity.
This role reports to Axel Save, Head of Factory Engineering.

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.
