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.

Role Summary

Responsible for the calibration and optimization of electric motor control features, and the integration testing of algorithms on dynamometer and vehicle platforms.

Responsibilities

• Develop and test electric motor control algorithms and calibrations for high‑power electric drive systems consisting of high voltage power converters and electric motors (such as surface mounted and interior permanent magnet machines, induction machines, and other machine technologies).
• Work with our controls and software developers to calibrate and validate the functionality of motor control features across vehicle dynamics, infotainment, connectivity, thermal, and other domains.
• Collaborate with other test teams to help ensure full test coverage across:
  • High‑voltage dynamometer tests
  • Hardware‑in‑the‑loop (HIL) tests
  • Sub‑component tests
  • Vehicle tests
• Maintain health of vehicle fleet and root‑cause software, mechanical, and electrical issues.
• Ensure successful integration in meeting performance specification of the electric drive system when integrating with various sub‑components or systems.
• Plan and perform regression testing for algorithm and calibration development.
• Collaborate with cross‑functional teams such as development, vehicle test, diagnostic, and service teams.
• Perform simulation and analysis of the electric drive system.
• Work as part of a fast‑paced, diverse team of professionals supporting component development and subsystem and vehicle integration.
• Participate in vehicle test trip support for cold and hot weather testing.
• Stay abreast of new technologies and competitive methods and products.
• Submit patents and trade secrets to advance Rivian intellectual property portfolio in the field of propulsion drive controls.

Qualifications

• M.S. in Electrical Engineering or Mechanical Engineering with background in motor control algorithms and electric machine characterization.
• 3+ years EV or equivalent experience.
• Fluency in the theory and principles of AC electric machine drive and three‑phase switching power converter topologies.
• Fluency in model‑based design using Matlab/Simulink, modeling and simulation of electric drives.
• Fluency in Git or other version control systems.
• Fluency in C/C++ and Python programming languages.
• Experience with tools for measurement and integration such as CANalyzer, CANape, or similar.
• Experience with vehicle testing.
• Able to travel domestically and internationally up to 30% based on business demands.
• Excellent interpersonal skills in a fast‑paced team.
• Good analytical and problem‑solving skills.
• Able to work with minimum supervision and full autonomy.
• Hands‑on experience working in high‑voltage high‑power laboratory and/or vehicle test environment.
