About the RoleRebaba builds circular battery systems from second-life EV batteries. Our solutions power buildings, industries, and charging infrastructure, combining mechanical design, electronics, and software into one integrated product. We design and assemble everything in Sweden with a clear mission: making clean, affordable energy accessible.We are now hiring a Mechanical Design & Product Development Engineer who wants to take mechanical concepts from sketch to real, field-ready products.ResponsibilitiesDesign mechanical parts, assemblies, and enclosures, both small modules and larger system componentsBuild and test prototypes, iterate quickly, and refine designs based on performance, safety, manufacturability, and costTake products from early concept to final, production-ready designs through structured, iterative developmentDesign for manufacturing, assembly, installation, and circularity across all mechanical componentsEvaluate and optimise thermal performance, ventilation, airflow, insulation, and fire-related design considerationsSelect materials based on sustainability, durability, circularity, and costSupport certification and compliance work related to mechanical design, including enclosure standards and safety requirementsWork closely with electrical and software teams to ensure alignment with electronics, wiring, cooling, and control systemsPrepare manufacturing documentation including drawings, BOMs, tolerances, and assembly instructionsCollaborate with suppliers and participate in sourcing decisionsRequirementsStrong skills in mechanical CAD such as SolidWorks, Fusion, or similarExperience designing enclosures, structural components, or industrial productsUnderstanding of manufacturing methods such as sheet metal, machining, plastics, composites, an…Civilingenjör, maskinCivilingenjörsyrken inom maskinteknik
