The role

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.

Key responsibilities

• Process Ownership & Scale-Up: Own, develop and optimize an assigned set of manufacturing processes within the company’s first commercial production plant. Proven experience with powder metallurgy, sintering, metallic powder mixing or similar technologies is expected.
• Methodology & Standards Creation: Drive development of process engineering methodologies, standardization frameworks and practical Ways of Working for factory execution, scaling and project delivery.
• Discipline Leadership: Provide technical and practical support to junior team members, leading by example and help establish a cross-functional culture of best practices within the realm of process engineering.   
• Design & Delivery: Design, develop and deliver technical solutions for the assigned scope; enabling safe and efficient manufacturing. Lead cross-functional collaboration, both internal and external, from design to optimized manufacturing. This includes equipment specifications and comprehensive technical documentation. 
• Supplier & Equipment Management: Lead equipment selection within assigned scope and ensure vendor fulfilment of milestones such as FAT/SAT, installation and commissioning.

Your profile

• Education: Bachelor’s or Master’s degree in Mechanical, Process or Industrial Engineering, or a related engineering field.
• Experience: 6-9 years of experience in mechanical, process, or manufacturing engineering roles within heavy industrial or advanced production environments.
• Project Delivery: Proven track record of leading process engineering projects and taking technical ownership of complex manufacturing lines from conceptual design through to commissioning and stable high-volume production.
• Methodological Expertise: Strong foundation in creating and implementing engineering methodologies and utilizing structured problem-solving tools.
• Vendor Management: Deep practical experience in defining equipment specifications, managing international equipment suppliers and overseeing equipment acceptance testing.
• Mindset: Structured, collaborative mentor and problem solver, highly comfortable leading through ambiguity and driving results in a fast-paced, rapidly evolving environment (startup or scale-up experience is a strong plus).

About us

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! Your unique perspective and skills could be exactly what we’re looking for.
