In this role, you will collaborate with the Electric Machine Mechanical Design Team to develop current and next-generation electric motors for Rivian’s Electric Adventure Vehicles. Your responsibilities will include generating motor concepts, designing components, creating drawings, developing tooling, supporting prototyping, conducting tests, and assisting with production.
-
Design sub-systems and components for various electric drive units, including wound field motor, permanent magnet motor, and motor mechanical structural components.
-
Generate & revise detailed 3D CAD models and 2D drawings of electro-mechanical designs at a component and motor sub-system level using CATIA V6.
- Review designs & drawings for completeness and accuracy.
-
Develop detailed work instructions, assembly guidance, and related documentation.
-
Analyze and verify preliminary and detailed designs with analytical calculations and numerical (FEA) as required.
-
Collaborate and manage suppliers with DFM, DFA, and open issues lists to ensure on-time delivery of parts and quality conformance according to the acceptance criteria.
-
Support developing component technical specifications, DVP&Rs, test & validation plans, and Statements of Work (SOW) as required.
-
Design of related assembly tooling and fixtures for early prototype development and testing.
-
Ensure timely completion of project deliverables, including designs, drawings, analyses, and other documentation as required.
-
Lead and support developmental activities of various laboratory work from assembly builds to test and validation with a hands-on approach.
-
Ability to travel to suppliers and Rivian manufacturing plants to support with experimental studies, root cause identification, and resolution.
-
Cross-functional collaboration with multi-disciplinary teams across Rivian.
Support root cause analysis studies to identify issue origin, determine appropriate containment plan, and permanent resolution for the issue.
-
- 5+ years of experience in mechanical design of complex systems and components, in a fast-paced environment.
-
Formal education in Mechanical Engineering or a similar discipline; B.S. minimum, MS Preferred.
-
Proficiency with 3D CAD modeling; CATIA V6 experience preferred.
-
Professional experience with application of GD&T (ASME Y14.5), conducting stack-up analyses (linear & radial), and determining realistic tolerancing limits based on material and manufacturing methods
-
Ability to perform structural hand calculations and initial FEA studies to support sizing, loading cases, and design feasibility.
- Proven ability to collaborate cross-functionally with technicians, manufacturing, process, design, and integration teams to solve problems.
- Knowledge of rapid prototyping, high-volume manufacturing processes, materials selection, and supply chain.
-
Hands-on experience with lab tools, equipment, and measurement tools.
-
Strong engineering fundamentals in the areas of materials, mechanics, dynamics, design for manufacturability, tolerancing, and high precision metrology.
-
Experience with leading root cause analysis efforts, determining effective containment actions.
-
Knowledge in DFMEA, DVP&R, and PFMEA.
-
High-energy, open-minded attitude, willingness to quickly iterate on designs, and expanding skillsets as needed.
