By owning the full stack from software to hardware, RIVR is purpose-built for safety, reliability, and the customer from day one.
We are seeking an experienced Mechanical Engineer to own the complete mechanical architecture, physical packaging, and harness routing strategy for our power distribution boards and control systems. Unlike traditional heavy EV inverters, our platform demands a lightweight structural approach while managing electronics packaging issues. In this role, you will lead the clean-sheet design of electronic enclosures, thermal management, and the complete wiring harness. You will act as the bridge between mechanical and electrical engineering, ensuring our systems are robustly packaged, sealed, routed, and ready for high-volume manufacturing.
Key job responsibilities Own the design and development process of electronic enclosures for our power boards and computational units, from concept to mass production.
Resolve complex mechanical challenges including electrical isolation, environment sealing, thermal management, shock and vibration, electromagnetic interference, etc.
Run required design analysis including thermal, CFD, structural (FEA), etc.
Define suite of test required to validate design together with testing team. Run root cause analysis and plan mitigations.
Create 2D drawings and supporting documentation for smooth handover to manufacturing team.
Guarantee manufacturability of parts and assembly. Lead supplier talks through DFM negotiations, run DFA analysis with manufacturing team.
- 6+ years of hands-on industry experience designing electro-mechanical assemblies, electronic enclosures, and wire harnesses for moving platforms. - Proficiency in CAD (Solidworks, Siemens NX, CATIA, etc.), experience with validation tools (e.g. Ansys, COMSOL, etc.). Knowledgeable with PLM systems - Robust understanding of mechanical principles (heat transfer, structural design, material selection, fluids, GD&T, etc.) - Experience on bringing prototypes to mass production using appropriate technologies like: die casting, injection molding, compression molding, thixomolding, progressive stamping, extrusion, etc. - Knowledgeable of material science used in electronic enclosures, gaskets and grommets. - Experience developing Test plans. And running appropriate root case analysis. - Understanding of electrical design, PCBa, components and it’s manufacturing process. - Bachelor’s or Master’s Degree in Mechanical Engineering, Mechatronics, or equivalent experience.
- Experience with harness design and routing. Collaborating directly with Electrical engineering team to select and specify appropriate connectors, terminals and wire gauges. - Generate wire harness 2Ds, layouts and pinout tables for manufacturers.
