At MacroCycle, we’re building a new approach to textile recycling. Today, most textiles end up in landfills or are burned, but our SolvoGenesis™ technology transforms that waste back into high-quality polyester fibers. By closing the loop on polyester, we’re helping to reduce landfill waste, lower production emissions, and move the textile industry toward a truly circular future.

What You’ll Do

• Work closely with senior members such as chemists and engineers to improve MacroCycle’s recycling process.
• Perform lab-scale chemical recycling reactions to upcycle PET and polyester materials derived from partners and customers.
• Use and maintain analytical instruments (e.g., NMR, GPC, FTIR) to test samples and record results.
• Keep detailed notes of experiments and share insights at team meetings.
• Help maintain lab equipment and supplies while ensuring a safe, organized lab environment.
  
  

Who You Are

• You have a Bachelor’s degree in Chemistry, Chemical Engineering, Materials Science, or a related field.
• You have at least 2 years of hands-on wet/chemistry lab experience. Research labs in a university count, but external internships or post-graduate work are preferred.
