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. 


  • Join the Cell Engineering Team, developing next-generation battery technology for Rivian’s products
  • Work with Electro-chemistry team to explore and develop tomorrow’s lithium-ion battery chemistry design and execution strategy.
  • We are developing key subcomponent technology on Anode, Cathode, Separator, and Electrolyte, all contributing to the best cell architectures possible.
  • Carry out experiments to optimize specific capacity, power, rate capabilities, cycle life, and cell safety for a given battery dimension and specifications.
  • Formulate accelerated, fast testing protocols (e.g., charging / discharging, C-rates, etc. for electrode design) in collaboration with simulation, pack, and BMS engineers.
  • Work collaboratively with some of the world’s best Cell engineers to optimize the battery’s efficiency, cost and lifecycle via empirical and theoretical modeling and simulation
  • Help us make the best electrode possible by identifying specific root cause and improving its critical metrics, including electro-chemical performance, material specifications, variations, and failure modes
  • Come together by working with other engineers and providing guidance to technicians.




  • BS Degree with a minimum of 3+ years of experience, or MS with 2+ years of experience, or entry level of PhD in chemistry, chemical engineering, materials science, mechanical engineering, or electrical engineering with hands-on experience from lithium-ion battery industry.
  • Demonstrate experience with lithium-ion battery cell chemistry development for EV battery cells. Product development or prototyping experience preferred.
  • Background in electrochemistry and/or electrochemical engineering
  • Experience in scaling up efforts between materials development, cell design, and large-scale manufacturing.
  • Bring an open-minded attitude to quickly gain knowledge on materials and design limitations
  • Strong understanding of electrochemistry and mechanical design that affect cell electrical and safety performance.
  • Ability to distinguish the difference between a practical engineering solution and an unrealistic idea. Zoom out to modify parameters that can benefit both battery performance and cycle life at cell-level, vs. achieving marginal improvement at a cost.
  • Exposure to multiscale modeling, data science, machine learning, and artificial intelligence and ability to comprehend cross-functional team discussions to collect data that can help improve overall cell design, to reduce the total number of experiments, cut down the cost, and save resources.
  • Comfortable on accepting and solving new challenges regarding electrochemistry, chemical system design, oxidation/reduction chemistry, electric and ionic conduction, and/or related energy storage technologies. Data interpretation and summarization for a large set of data being generated from electrode and cell design, assembly, and formation processes.
  • Experience building a large format EV cell. Perform necessary materials characterizations and cell characterization evaluations (i.e., HPCC, charge/discharge rate test, cycle life, calendar life, and safety test), in discussion with subcomponent project leaders and other subject-matter experts.
  • Perform electrochemical analysis such as CV, EIS, GITT, and/or PITT and materials characterization such as SEM, XRD, XPS, Raman, FTIR, BET, TGA/DSC, and/or ICP.
  • Experience and ability to work in a chemistry lab setting
  • Working with cross-functional team members on industry standard electrode processing steps, i.e., slurry mixing, coating, calendaring, and drying in manufacturing scale.
  • Experience in risk analyses, including Design Failure Mode and Effect Analysis (DFMEA) to define risks and carry out root cause analysis
  • Ability to carry out design of experiments
  • Can convey technical information in non-technical format at varying levels of technical competence, including executive leadership
  • Critical problem-solving skills: ability to ask the right people, the right questions at the right time in the right way!
  • Curiosity: demonstrate level of interest that enables inventiveness
  • Execution: demonstrate that follow through is given as much attention as problem solving
  • Structured: able to organize chaos thru methodical framework and documentation to achieve goals harmoniously.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Rivian Automotive’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. 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.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past.
