Rimac Energy develops the future of power conversion and battery management, extracting the maximum performance potential of battery energy storage systems.
We engineer the hardware, software, and intelligence that improve efficiency, usable energy, and lifetime.
Our edge is deep integration - power conversion built into the battery module itself, with batteries, power electronics, software, and thermal management engineered as one system, European-designed and built.
We are fast-moving, technically ambitious, and results-driven, and you will work on genuinely complex problems alongside people who care deeply about what they build.
We expect a lot, and we offer a lot: real ownership, real products, and the chance to contribute to technology that pushes the boundaries of what energy systems can do.
About the role
We are looking for a Mechanical Hardware Designer to own the mechanical design of enclosures, busbars, harness routing and packaging for our grid-connected inverters and energy storage hardware - from concept through prototype and validation into production.
You will own your assigned parts and commodities end to end, working at the interface of mechanical design, electrical engineering, CAE, suppliers, and manufacturing.
This role is based at our Witney, Oxfordshire site.
Responsibilities
- Mechanical hardware design
- Own component design for all assigned parts and commodities - electrical routing, thermal routing, structural enclosures, assembly features, and packaging constraints
- Ensure mechanical requirements are met, reviewed, documented, and signed off before design release
- Create, maintain, and release accurate 3D models, 2D drawings, design data, and production documentation
- Support mechanical component selection by assessing package, material, process, cost, supplier capability, validation, and serviceability constraints
- Define materials, finishes, coatings, plating, fasteners, torque requirements, and interface details for conductive and structural components - electrical contacts, busbars, brackets, enclosures, grounding hardware
- Support virtual builds and build-process documentation to confirm assembly sequence, access, tooling clearance, routing, serviceability, and repeatability
- Electrical packaging and integration
- Translate electrical diagrams, schematics, wiring information, control and communication interfaces, and safety needs into practical mechanical packaging solutions
- Package PCBs, contactors, fuses, filters, sensors, connectors, cable glands, busbars, cooling systems, brackets, and associated enclosures
- Support EMC-aware packaging - cable routing, filter placement, grounding, bonding, shielding, segregation, conductive interfaces, and enclosure-level design features
- Contribute to design decisions balancing efficiency, grid compliance, EMC performance, safety, cost, thermal performance, manufacturability, and launch timing
- CAE, verification, testing and launch
- Interface with the CAE team, interpreting simulation results and converting them into design actions meeting mechanical, thermal, structural, vibration, and durability requirements
- Support testing, prototype build, verification, integration, and launch with build notes, design data, fixtures, packaging updates, and rapid issue resolution
- Capture build feedback, test observations, fit issues, tolerance concerns, supplier questions, and design risks
- Use structured problem-solving to identify issues, containment actions, root causes, countermeasures, and robust design improvements
- Supplier, customer and cross-functional working
- Support supplier and customer interaction covering DFM, tooling, verification, integration, issue resolution, cost, delivery timing, and design maturity
- Conduct cross-functional reviews for high-priority tasks and where risk, timing, or integration impact warrants wider review
- Solve complex problems by drawing on expertise across the team, supply chain, and wider industry
- Cost, supply chain and delivery ownership
- Support cost analysis, design-to-cost trade-offs, supplier feasibility reviews, and cost-reduction activities without compromising requirements or launch quality
- Coordinate with supply chain to ensure parts are ordered, tracked, and delivered to MRD timings
- Communicate part and commodity status clearly - release status, supplier manufacture, expected delivery, PO status
- Operate a robust task and time-management process, escalating risks early with clear mitigation plans and revised target dates
- Documentation and process
- Develop and maintain Jira tickets, Confluence documentation, design review materials, decisions, open issues, and sign-off evidence
- Maintain part naming, attributes, drawing references, release information, and EBo M structure to company standards
- Ensure all due dates are met, or that robust mitigation is communicated with new target dates before deadlines are missed
Requirements
- Technical background
- Degree, apprenticeship, HNC/HND, or equivalent practical experience in Mechanical Engineering, Product Design, Mechatronics, or a related field
- Strong experience creating mechanical designs for electrical, electronic, power-electronic, or energy-system hardware
- Confident using 3DEXPERIENCE CAD and 2D drawing tools, with strong knowledge of GD&T, tolerancing, materials, finishes, and production documentation
- Ability to read and interpret electrical diagrams, schematics, wiring diagrams, interface documents, system requirements, and packaging constraints
- Working understanding of electrical packaging - routing, shielding, grounding, creepage, clearance, heat dissipation, isolation, and service access
- Practical experience
- Experience supporting prototype builds, virtual builds, product integration, design validation, or low-volume manufacturing
- Exposure to enclosures, harness routing, busbars, connectors, PCBs, filters, terminals, cooling systems, sensors, brackets, and mounting systems
- Ability to balance electrical performance, mechanical robustness, compliance, cost, MRD timing, and build practicality in a fast-moving environment
- Excellent communication skills, with the confidence to challenge assumptions and resolve interface issues across mechanical, electrical, CAE, supplier, and manufacturing teams
- Structured approach to problem solving, Jira management, drawing release, design reviews, documentation, requirements traceability, and EBo M discipline
- Considered as an Advantage
- Experience with battery energy storage systems, inverters, power conversion systems, grid-connected equipment, or high-voltage/high-power assemblies
- Experience designing or packaging inverters, power distribution units, control enclosures, harnesses, or thermal management commodities
- Familiarity with EMC design principles - EMC filtering, shield termination, bonding, earthing, and standards such as IEC 61000 or equivalent
- Awareness of product compliance and electrical safety standards for grid-connected or power-electronics products: IEC 62477, UL 1741, EN 50549, G99, or equivalent
- Experience with requirements, PLM, issue-tracking, and documentation tools such as Jira, Confluence, 3DEXPERIENCE, or similar
- Hands-on understanding of component testing, supplier development, tooling, cost analysis, manufacturing methods, and design-for-assembly improvements
What We Offer
- Technically challenging, high-impact work on advanced energy storage and power conversion products - from concept through prototype, validation, and production
- Real ownership of your parts and commodities, with visibility across the full product lifecycle
- A collaborative, cross-functional engineering culture with strong links between mechanical, electrical, controls, software, compliance, CAE, test, supply chain, and manufacturing
