About The Company
Solid Power is an industry-leading producer of all-solid-state rechargeable batteries for electric vehicles and mobile power markets. Solid Power replaces the flammable liquid electrolyte in a conventional lithium-ion battery with a proprietary sulfide solid electrolyte. As a result, Solid Power's all-solid-state batteries are safer and more stable across a broad temperature range, can provide a 50-75% increase in energy density compared to the best available rechargeable batteries, enable cheaper, more energy-dense battery pack designs and are compatible with traditional lithium-ion manufacturing processes.
About the Role

Position Overview:

Solid Power is seeking a Materials Engineering Intern to join our talented team of engineers and scientists dedicated to advancing next-generation all-solid-state battery technology. In this role, you will contribute to cutting-edge research and development efforts focused on revolutionary energy storage solutions that are shaping the future of the battery industry.

Job Duties:

  • Work closely with Engineers to support and execute experimental plans focused on optimizing sulfide solid-state electrolytes.
  • Assist with data collection, analysis, and interpretation of experimental results. 
  • Support polymer processing activities, including slurry preparation, mixing, casting, coating, drying, and material handling for development-scale experiments.
  • Document process conditions, observations, and results to support process optimization and scale-up efforts. 
  • Maintain a clean, organized, and safe work environment through routine housekeeping activities. 
  • Safely handle hazardous materials, chemicals, and laboratory equipment in accordance with established procedures.

Qualifications/ Requirements:

  • Currently pursuing a Bachelor's or Master's degree in Materials Engineering, Chemical Engineering, Chemistry, Polymer Science, or a related field.
  • Knowledge of materials characterization techniques. 
  • Familiarity with polymer processing or wet-chemical materials processing methods, such as mixing, slurry preparation, casting, coating, or drying, is preferred. 
  • Understanding of safe handling practices for hazardous materials and laboratory equipment. 
  • Experience with synthetic chemistry is a plus. 
  • Knowledge of lithium-ion battery materials, synthesis methods, and materials optimization is preferred.
  • Ability to work on-site at our Louisville, CO location. 
  • All offers of employment at Solid Power are contingent upon clear results of a thorough background check.

Physical Requirements: 

  • Ability to sit and work at a desk for extended periods. 
  • Ability to stand for prolonged periods while conducting laboratory or production activities. 
  • Ability to lift up to 50 pounds. 
  • Must be able to wear the required Personal Protective Equipment (PPE), including safety glasses, gloves, face coverings, hair nets, safety shoes, coveralls, respirators, or PAPRs as needed. 

Hourly Compensation: $25/hour

Schedule: 10-20 hours per week during fall semester.

Application Deadline: This role will be posted until a suitable candidate has been identified. 

Export Control Requirements:
