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
This role is a key bridge player between our lab work and industrialisation for iron anode development, working in a hands on capacity to process powders from raw materials to end product. You'll be constructing the incoming materials properties & process to the product as well as documenting the process.You’ll take powders from incoming spec to qualified parts: develop blends, choose forming routes, run debind/sinter with controlled atmospheres, and lock robust process windows. Expect pilot-line trials, data-driven tuning, clear SOPs and specs, and tight collaboration with R&D, Quality, Manufacturing, and suppliers. The role is ideal for a powder metallurgy specialist that is looking to work hands on with the product rather than just the research sideKey responsibilities
• Lead end-to-end optimization of iron powder processing: powder selection/spec, blending, binder/lubricant strategy, compaction , debinding/dewaxing, and sintering (time/temperature/atmosphere).• Engineer porosity, tortuosity, and conductivity to meet anode performance and cost targets.
• Design and run structured experiments (DoE), analyze results (SPC/Minitab/Python/Excel), and lock parameters into robust work instructions.
• Qualify and scale processes from lab to pilot/production (yield, Cpk, cycle time)
• Specify and optimize equipment: presses, tooling, furnaces (belt/tube/vacuum), gas-handling and safety systems.
• Implement quality controls and metrology: density/porosity microstructure (SEM/EDS), composition analysis (OES), phase analysis (XRD), mechanical tests (hardness/compression).
• Collaborate with electrochemistry colleagues on build/measure/learn loops; translate cell feedback into process changes.
Your profile
• 5+ years industrial powder metallurgy experience (press-and-sinter metals; iron/steel experience strongly preferred).• Hands-on mastery of compaction, debinding, and sintering under controlled atmospheres (H₂/N₂/inert/vacuum); understanding of furnace design and thermochemical reactions.
• Track record improving yield, uniformity, and throughput using DoE and data-driven methods.
• Experience tuning porosity and microstructure via powder PSD, green density, additives, and thermal profiles.
• Practical knowledge of safety for metal powders (combustible dust, gas handling).
• Clear documentation and cross-functional communication skills.
Bonus Skills:
• Exposure to electrochemical systems: assembling coin/pouch/cell fixtures, basic galvanostatic cycling/EIS, interpreting cell data.
• Scale-up in a regulated environment (ISO 9001/IATF 16949/AS9100).
• Scripting/data tools (Python/R/Matlab), Minitab, or MES/ERP familiarity.
