About The Position

Rivian is seeking an electromagnetic engineer to design, model, and analyze high-performance electric motors and actuators. The role also develops computational methods, analytical modeling algorithms, and multi-objective optimization tools to improve simulation fidelity and accelerate design iterations. The engineer works with Thermal, Mechanical, NVH, Vehicle Integration, and Physical Validation Labs teams to meet automotive-grade reliability, efficiency, and cost targets. The role provides technical support for component-level testing and establishes simulation-to-test alignment pipelines to improve finite-element accuracy and reduce physical prototyping. It also collaborates across functions to address manufacturing and production issues, perform technical root-cause analysis, and troubleshoot prototype builds and high-volume production-line issues.

Requirements

PhD in Electrical Engineering with an emphasis on electromagnetic design of e-machines and at least 5 years of experience.
Experience designing and analyzing high-torque- and power-density IPM/PM and induction electric machines.
Expert-level skills with electromagnetic analysis tools such as JMAG, COMSOL, and ANSYS/Maxwell.
Experience using MATLAB/Simulink for data analysis.
Strong understanding of validating motor electromagnetic and thermal designs, including performance and durability.
Good understanding of e-machine build processes in both prototype and high-volume manufacturing stages.
Self-motivated, with the ability to manage multiple tasks efficiently and accurately.
Flexibility and adaptability in a fast-paced, dynamic work environment.

Responsibilities

Lead in-house electromagnetic design of e-machines to support Rivian’s product development plan.
Determine e-machine electrical and mechanical specifications in support of Rivian’s product roadmap.
Perform electromagnetic analysis, modeling, and design of electric machines for Rivian products.
Carry out R&D activities to develop high-quality motors for production programs.
Develop, verify, and optimize modeling tools and design processes to predict and optimize electric-machine performance.
Develop test plans and work with motor-control and/or testing teams to validate electromagnetic and thermal performance.
Develop material databases through in-house testing of electric-motor active components, including electrical steel, magnet-wire insulation, and permanent magnets.
Support structural and mechanical analysis of motor systems, including NVH and durability.
Support and/or perform thermal analysis to predict electric-machine thermal characteristics.
Work with mechanical engineers and/or designers to create motor 3D models and 2D drawings and release them to manufacturing.
Support powertrain system integration and vehicle-control integration.
Support motor-manufacturing development, including material selection and process evaluation.
Study, invent, and implement new electric-machine technology.
Provide technical support for component-level testing and establish simulation-to-test alignment pipelines.
Collaborate across functions to resolve manufacturing and production issues, perform root-cause analysis, and troubleshoot prototype builds and high-volume production-line issues.
