About the company:
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
We are expanding our industrialization capabilities and are looking for a Process Engineer to join our Factory Engineering team in Amsterdam. You will operate at the intersection of process design, equipment implementation and production scaling, translating product and technical requirements into stable, efficient and safe manufacturing solutions.
You will own a set of core process steps, collaborating with R&D, Product Design, Operations and equipment suppliers to define process parameters, write specifications and bring a robust manufacturing system into large-scale operation. This is a hands-on, execution-heavy role in an early factory design environment, requiring strong ownership and initiative.
This role reports to Axel Save, Head of Factory Engineering.
Key responsibilities
Own and develop a defined set of manufacturing processes within the company’s first commercial production plant (e.g. mixing, calendering/pressing, chemical treatments and other core production processes). Experience in any of these areas is a strong plus.
Design and detail assigned manufacturing steps, including process flows, equipment specifications and technical documentation.
Translate product and design requirements into stable, repeatable and scalable production solutions; enabling manufacturability in close collaboration with R&D and Product Design stakeholders.
Actively support equipment selection, supplier interaction, installation and commissioning for the assigned processes.
Support commissioning and ramp-up through troubleshooting, root cause analysis and continuous improvement initiatives.
Ensure assigned processes meet safety, quality, and sustainability requirements, in both ramp-up and steady-state production.
Your profile
Bachelor’s or Master’s degree in Mechanical, Process, Chemical Engineering or a related engineering field.
3+ years of experience in mechanical, process or manufacturing engineering roles in industrial or production environments.
Hands-on ability to take technical ownership of manufacturing processes from concept through commissioning and stable production.
Strong practical foundation in process design, equipment specifications and supplier interactions, technical documentation and ramp-up troubleshooting.
Structured, collaborative problem solver, comfortable working cross-functionally in a high-ambiguity and rapidly evolving environment (startup experience is a plus).
What to expect from our recruitment process?
1. 15min initial screening call with People & Talent Lead focussing on your motivation and interest in working for Ore Energy as well as fit for the role & wider team.
2. 45-60min technical interview with Hiring Manager for the role (or another member from the team)
3. 90min case study with Hiring Manager and other members of the team
4. Final interview (if needed)
Check-ins with People & Talent lead will happen throughout the process.
