About The Position

At MacroCycle, we’re building a new approach to textile recycling.

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.
You’re familiar with at least two analytical techniques such as NMR, GPC, GCMS, FTIR, ICP, or DSC.
You’re detail-oriented, curious, and enjoy solving practical problems.
You are a great communicator, both verbally and in presenting your work with comprehensible Excel graphs and PowerPoint slides
You thrive in a collaborative, fast-paced environment, and take pride in careful, high-quality lab work.
