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.

As a Staff Engineer‑ Manufacturing Engineering ‑ Dimensional, you will create geometric dimensions and tolerances, analyze them via design variation analysis tools, provide feedback and set GD&T and tolerancing requirements to product design, and be a key technical leader for the team responsible for developing the dimensional strategy for Rivian's new products. This includes helping to develop the assembly process for Body Structure, Drive Unit, and General Assembly working cross‑functionally with Manufacturing Engineers, Design Release Engineers, and Supplier Development Engineers to ensure successful product launches at Normal, IL and our new green‑field facility in East Atlanta, GA, as well as overseeing Design Validation Builds in the metro Detroit area.

This role is located at our Normal, IL facility and reports directly to a Sr. Manager, Manufacturing Engineering.

• Assure that all buy‑off criteria is upheld for all parts/assemblies through final approval, to include but not limited to:
  Certification, R&R, EC Level, part quality.
• Lead and mentor others in the Dimensional Control Engineering Department
• Work as a champion of good, fundamental design across the vehicle
• Work upstream in the design process to develop and assess feasibility of design targets for key vehicle sub‑systems.
• Cross‑functional development and documentation of assembly datum schemes and in‑process dimensional specification requirements to ensure robust product manufacture.
• Perform part and assembly tolerance stack analysis and provide feedback to product and manufacturing engineering team.
• Development of key product maturation tools to be used in conjunction with quality loops to drive towards product excellence during new product introduction.
• Root Cause launch issues in a data‑driven way.
• Participate in Virtual and production Build events.
• Knowledge of an automotive design and development process, system requirements, and general engineering best practices
• Understanding of various methods of component forming and assembly and associated part or assembly tolerances
• Experience with component specification standards and ANSI standards for GD&T
• Ability to review a design and process and provide suggestions to improve the repeatability of design
• Experience with fixture design and the ability to troubleshoot fixture method repeatability issues.
