Design Engineer, Powertrain Drive Unit Architect at Rivian

About Rivian
Rivian is on a mission to keep the world adventurous forever. This goes for the emissions‑free electric adventure vehicles we build, and the curious, courageous souls we seek to attract. As a company, we constantly challenge what’s possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown.

Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.

Role Summary
In this position, you will be part of the Powertrain Drive Unit team, and you will lead the establishment of advanced DU drive unit design concepts for future programs. You will participate in cross‑functional technical integration meetings; and you will lead new program DU design concepts from layout to 3D assembly math. You will lead design concept maturity development in 3D math, in order to collaborate cross‑functionally and to freeze design concepts at the Concept Design Exit Phase of the Rivian development cycle.

The Maturity level at CDE is proof of drive unit design concept feasibility, and ok to proceed to Detailed Design Phase. For this position, the candidate will bring a strong principle based engineering skillset in powertrain driveline power transmission systems; and they will also be required to be proficient in CATIA (V6 preferred) and capable of developing design concepts and maturity in 3D CAD.

It is required that the candidate possess a strong skillset in 2D stack‑up analysis and 3D CAD based tolerance stack analysis skillset is desired. If the candidate does not possess this 3D stack‑up skillset, we are seeking a candidate that would like to pursue this skillset thru formal training and project execution. This position will be located at our Plymouth, MI facility and reports directly to a Technical Manager.

• Lead drive unit concept maturity from layout to 3D math with focus on developing concept design maturity to evidence based proof of concept feasibility phase and CDE exit.
• Lead creation of parametric 3D mechanical design of component parts, sub‑assemblies, and final assemblies for Rivian Drive Units, and advance projects in CATIA. 3D math quality up to CDE is not critical up to CDE, as this is conceptual phase for design maturity development.
• Lead/execute 3D DU and Vehicle Level packaging studies of design concepts considering package envelope, system performance and manufacturing feasibility.
• Lead Pugh Matrix based trade‑off studies for DU System Architectural Cross‑Functional Decision Points, as required.
• Collaborate directly with DREs and with cross functional teams such as CAE, EE, manufacturing engineering, vehicle packaging, and systems engineering.
• Support and participate in design reviews DU subsystem and system level cross‑functional buy‑off.
• Perform part and assembly 2D/3D tolerance stack analysis and provide feedback to product and/or manufacturing engineering teams.

• In‑depth understanding of EV propulsion system components/subsystems.
• Minimum 5 years of experience using CATIA (V6 preferred).
• Experience using ENOVIA Product Lifecycle Management (PLM) system or equivalent.
• DFM knowledge relative to machined die‑castings, plastic injection/molded parts, gears/bearings, bolted joints, etc.
• Able to apply DFA for manufacturing of power electronics and vehicle integration.
• Strong knowledge of GD&T and its application to part manufacturing and assembly tolerancing.
• Proficient with Microsoft Office apps (Excel, PowerPoint, Word) or Google Productivity apps (Google Docs, Sheets, Slides) which is preferred.
• Must be detail oriented, self‑motivated, and a quick learner who is able to work in a fast‑paced environment.

• Expertise in 3D tolerance stack analysis, 3
  
  DCS preferred.
• Expertise with FEA analysis tools, and other CAE tools that can be used for early concept development.

Salary Range – Michigan‑Based Applicants: $125,800–$157,200 (actual compensation will be determined based on experience, and other factors permitted by law).
