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

If you are aligned with this mission, we want you to join our team. We're looking for a highly motivated, experienced, multi-disciplined, mechanical integration leader to challenge what is possible in the development of our electronic hardware components and architecture. Help Rivian lead the way in the future of the EV industry.

Responsibilities
  • Lead the integration and package of a wide variety of electrical components in CAD, such as ECUs, microphones, switches, power outlets, USB ports, sensors, and new end user electronic devices for innovative applications on our vehicles.
  • Work with harness leads to optimize architecture focused on cost, mass and part count. Focus ideas on combining and eliminating redundancy and components to streamline designs and manufacturing processes.
  • Push the limits to optimize vehicle mechanical architecture, and electrical system integration into the overall product and process, driving engineering tradeoffs to obtain cross functional and leadership alignment.
  • Partner with manufacturing engineering to drive new ideas to minimize assembly time, drive designs that deliver high first pass factory yields, and high field reliability.
  • Collaboratively design mechanical components by interfacing with multiple business functions within the company in support of electrical hardware such as ECUs, antennae, displays, harnessing, switches, audio, sensors, and power systems.
  • Develop and document component mechanical functional requirements based on product requirements for custom, semi-custom, and off-the-shelf components.
  • Consider all aspects of integration such as UI/UX, design, EMC, service, manufacturing build feasibility, thermal, durability, mounting, ensuring correct clearances, NVH, water/dust ingress, component functionality, perceived quality, etc.
  • Complete component design verification plans to ensure we deliver low mass, low cost, yet durable parts and modules to the vehicle program.
  • Research and benchmark competitors and cross industry technologies
  • Perform other duties as required or assigned within the scope of the position
Qualifications
  • At least 10 years industry experience within automotive or other industries (consumer electronics, biomedical, aerospace, etc.)
  • B.S degree (or above), in mechanical engineering, or relevant equivalent experience.
  • Experience designing components and /or systems that include mechanism design, thermal design, PCB integration, sensor integration, user interface/user experience (UI/UX) considerations, and class A surface integration.
  • Experience problem solving electrical architecture challenges, solving grounding, EMC and antenna challenges.
  • Experience leading cross functional teams in matrixed organization to innovate and drive new ideas and solutions into products.
  • Be a proficient CAD designer, ideally within Catia V5 / V6 / 3DX, though other equivalent systems will be considered. Advanced surfacing and solid modelling expertise is preferred, along with strong CAD structure/organizational skills.
  • Great problem solving and communication skills.
  • Ability to identify optimization opportunities from CAE/testing results.
  • Excellent knowledge of manufacturing methods such as sheet metal brake-press and stamping, injection molded plastic, cast metals, CNC machining, 3D printing etc.
  • Experience in a wide range of EV vehicle systems, automotive design and manufacturing practices, and low-voltage electrical system integration. Direct experience is preferred.
  • Workable knowledge with DFMEA principles and execution.
