About Us
Rimac Energy is a technology company at the forefront of advanced battery energy storage, power conversion, and control systems for demanding, fast-moving energy applications. We design and build hardware that solves hard problems — from grid-connected inverters and energy storage systems through to high-voltage power distribution and accessory control products used in real-world deployments.
Our teams span mechanical design, electrical engineering, software, controls, compliance, testing, supply chain, and manufacturing. We are fast-moving, technically ambitious, and results-driven. If you join us, you will work on genuinely complex problems alongside engineers who care deeply about what they build.
We expect a lot. We also offer a lot: real ownership, real products, and the chance to contribute to technology that pushes the boundaries of what energy systems can do.
Key Responsibilities
Mechanical Hardware Design
Own component design for all assigned parts and commodities, including 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 — including electrical contacts, busbars, brackets, enclosures, and grounding hardware
Support virtual builds and build-process documentation to confirm assembly sequence, access, tooling clearance, routing, serviceability, and repeatability
Electrical Packaging & Integration
Translate electrical diagrams, schematics, wiring information, control and communication interfaces, EPB and safety needs, and hardware requirements 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 — including cable routing, filter placement, grounding, bonding, shielding, segregation, conductive interfaces, and enclosure-level design features
Contribute to design decisions that balance efficiency, grid compliance, EMC performance, safety, cost, thermal performance, manufacturability, and launch timing
CAE, Verification, Testing & Launch
Act as an integral interface with the CAE team, interpreting simulation results and converting them into design actions that meet mechanical, thermal, structural, vibration, and durability requirements
Support testing, prototype build, verification, integration, and launch activities 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 & 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 where needed
Cost, Supply Chain & 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 — including release status, supplier manufacture, expected delivery, and PO status
Operate a robust task and time-management process, escalating risks early with clear mitigation plans and revised target dates
Documentation & 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 EBoM structure to company standards
Ensure all due dates are met, or that robust mitigation is communicated with new target dates before deadlines are missed
Required Skills & Experience
Techincal 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 EBoM discipline
Considered 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
Fast-paced environment where practical problem-solving and initiative are genuinely valued
Continuous learning and development, with exposure to rapidly evolving energy and power electronics technology
A friendly, ambitious team that works hard and takes pride in what it builds
