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. 

This is what you’ll do:

  • Reliability is at the core of Electric Adventure Vehicles. As a Polymer Materials Engineer in the Materials Engineering team, you will play a key role in generating insight through leading the establishment and creation of polymer materials specifications, and testing standards participating in failure analysis investigations for all Rivian products from the vehicle to component level.
  • The Polymer Materials Engineer will serve as the one of the subject matter experts for the Materials Engineering team in the field of polymers and adhesives identification, characterization, and their failure analysis.  

Core responsibilities:

  • Drive materials development, selection, qualification, standardization, and approval in the areas of plastics and adhesives for high quality on-road and off-road electric vehicles.
  • Collaborate and develop strong partnerships with engineering teams (e.g. design, manufacturing, plant quality, supplier quality, supply chain, design for sustainability, etc.) to define their needs for materials recommendation and process optimization. Maintain a constant dialogue on the existing and growing capabilities in polymer expertise and in characterization equipment.
  • Participate in failure analysis activities for incidents originating from reliability testing for new product development and from fielded systems. Assure that root cause is identified at the most detailed level.
  • Lead the establishment and creation of materials specifications, and testing standards.
  • Establish and maintain key material supplier relationships with a focus on process and material sustainability. Perform supplier audits as needed.
  • Drive innovation with suppliers and partners.
  • Lead executive reviews related to Materials Engineering projects.


this is what you’ll need:

  • PhD or MSc in Materials Science/Engineering, Polymer Science, Chemistry, or Physics.
  • 10+ years of experience in the development, test, and performance evaluation of polymeric materials (plastics and adhesive) to being able to influence design and advise on formulation and manufacturability of the material (e.g. through injection molding, extrusion, lamination, vulcanization, thermo forming, casting, etc.).
  • Experience drafting materials specifications and supplier qualification; PPAP, including DFMEA, PFMEA, etc.
  • Strong fundamental knowledge of polymers and polymer chemistry, and an in-depth knowledge of polymer characterization, structure-property-performance relationships, and failure modes.
  • Hands on experience with polymer characterization techniques such as, mechanical testing, FTIR, DSC, TGA, DMA, rheology is required. Experience with Raman, GC-MS, GPC, NMR, XRD, is a plus.
  • Experience with mechanical testing such as Instron, hardness, fatigue, creep, etc.
  • A working knowledge of other common materials characterization laboratory equipment and techniques such as optical microscopy, SEM, EDS, CT-Scanning, 2D X-ray, is a plus. 
  • Knowledge of DOE and statistical data analysis tools e.g., Weibull, Nevada Charts, etc.
  • Experience reading CAD and creation/modification of models is a plus. 
  • Experience drafting materials specifications and supplier qualification; PPAP, including DFMEA, PFMEA, etc.
  • Experience with rubber and soft goods. E.g., for interior applications and body closures (seals).
  • Be able to create exceptional visualizations and direct the communication and presentation of findings to project teams.
  • Effective in managing multiple projects to achieve rigorous standards and meet demanding schedules and drive the corrective actions necessary to mitigate the risk of future failures.
  • Experience effectively presenting and communicating highly complex technical information in a manner appropriate to a variety of audiences, from the fellow scientist to the executive level.
  • A desire to create a respectful, fun, inclusive and inspiring team and company culture is a must!

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.
