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. 

Main responsibility includes contributing to the development of new lithium-ion battery models for the Battery Management System control unit. You will work on future algorithmic control systems which predict battery performance & life, while developing an understanding of the present BMS’ ability; the inputs, outputs, memory, timing and general software of the processing unit. You must:
  • Hold an understanding of li-ion battery electrochemical behavior,
  • Possess firmware & Model-Based-Design development skills.
  • Have experience with electrical and software testing, along with automated data analysis
  • Possess an understanding of control-system concepts with safety best-practices in mind.
  • You will utilize your knowledge of model-based design programming- as well as C programming- to create new software components for the latest automotive BMS applications.
  • The successful candidate must be proactive, driven by detail, and an individual who can work both independently, and alongside with other programmers, validation engineers, and battery scientists on a variety of exciting applications.
  • Use best-practices, experience, and talents to create battery models for production ECU:
    • Assess input & output constraints to best develop models which become executable code
    • Devise creative methods to predict State of Charge (SOC), State of Health (SOH), Power Prediction (SOP), Temperature Estimation & Heat Generation
    • Utilize a variety of debug tools to aid and speed your development; writing scripts, GUI’s, & executables
    • Work with systems engineers to apply ISO-26262 functional safety standards in your work
    • Design other important software components of the BMS, involving diagnostics, fault detection, and more
  • Coordinate & work with engineers across multiple disciplines to ensure timely completion of assigned tasks:
    • Collaborate with software engineers to integrate application-layer software into RTOS
    • Collaborate with validation engineers to test your models & firmware functionality
    • Validate your designs on real battery cells, packs, and vehicleso Share progress & participate in code reviews with algorithm & control systems designers
    • Work with project management to evolve features and functions to future Rivian platforms
  • Grow and mature as the development and production process evolves:
    • Transition between C-programming and Model Based Design (Matlab/Simulink)
    • Understand corner-cases, importance of unit-testing, and battery performance limitations
    • Apply lessons learned to future designs and firmware implementations
    • Contribute to data analysis efforts
    • Show willingness to take on dynamic projects; from cell testing, to off-line physics modeling, over-the-air (OTA) data transfer methods, all the way to machine learning
  • Internship or research experience in the battery and/or automotive industries
  • At least a bachelor’s degree in engineering discipline
  • Experience with Model Based Design; familiarity with embedded software development & C programming a plus
  • Experience with model-based design; creating control systems & models with Matlab/Simulink
  • Excellent problem-solving skills; reliant on core engineering principals & common sense
  • Strong communication, multitasking, & inter-personal skills, both in presentation & technical writing
  • Versed with working toward project requirements

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.
