Junior Mechanical Engineer

Ore Energy B.V. Junior Mechanical Engineer Amsterdam Full-time Permanent employee Apply for this job The role At Ore Energy, we are on a mission to fundamentally expand the amount of energy society can reliably harness and 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 technical development capabilities and are looking for two Junior Mechanical Engineers to join our team in Amsterdam. In this role, you will support the mechanical design, prototyping, and testing of our breakthrough iron-air battery cells, modules, and supporting hardware systems. Operating at the intersection of electrochemistry, materials science, and physical systems engineering, you will translate theoretical product requirements into practical, physical, and testable mechanical designs. This is a highly collaborative, hands-on, and iterative role for a curious, creative, and detail-oriented engineer who loves building, testing, and troubleshooting hardware in a fast-paced laboratory and workshop environment. Key responsibilities - CAD & Design Ownership: Create, update, and manage high-quality 3D CAD models, complex assemblies, and detailed engineering drawings for battery housings, seals, supports, and internal components. - Hands-on Prototyping: Build, modify, and inspect physical prototypes for development, structural analysis, and validation testing. - Testing & Troubleshooting: Actively participate in mechanical testing, experimental setup, and troubleshooting of prototype designs to assess tolerance, sealing, fit, and durability. - Root-Cause Analysis: Identify design weaknesses, contribute to root-cause failure analysis, and propose creative engineering improvements to simplify assembly, safety, and reliability. - Basic E...
