About Us
Ambercycle is a materials company founded in 2015 to create a circular supply chain for the apparel industry, making decarbonized raw materials across industry verticals. We're doing this by developing and deploying new technologies to increase the scope and scale of regenerated materials in the global apparel supply chain, and reduce the use of raw agricultural and petroleum resources. Our products avoid the use of new raw materials and go into the highest quality applications, exceeding the expectations of end customers with a fraction of the environmental footprint. Our success is the result of the talent, curiosity, and drive of our people. They bring solutions every day to realize our vision to improve humanity’s relationship with the material world.

The Job
The Principal Scientist will develop and help scale our technology for making regenerated polymers from end-of-life textiles. You will help bring Ambercycle’s innovative technology out of the lab and into commercial operation. You will be responsible for experimental process design and implementation and will work closely with the R&D and Engineering leadership to understand and prioritize process improvements, design experiments to make those improvements, and execute these plans in the laboratory. You will develop analytical methods for R&D as well as scale-up and develop new products within our R&D team. This involves designing and constructing bench-scale equipment and experimental setups, conducting experiments, performing detailed analysis of results, and writing technical reports. You will use your chemistry know-how to work with engineers and technologists and scale-up processes from the laboratory to global commercial scale. You are detail oriented and highly enthusiastic about science and scaling a first-in-kind sustainable process. You have a strong experimental background and commanding knowledge of physical, organic, and polymer chemistry. You must be comfortable in a fast-paced, open environment with minimal direction. The successful candidate has conducted lab and pilot scale experiments, and understands how to improve process efficiency and reduce cost. The ideal candidate will be driven, confident, and will do what it takes to ensure successful development and scale-up of our process technology.
Who You Might Be
You are insatiably curious about the world around you. There is nothing more thrilling to you than getting a new piece of information, all the better if you’re the first person to see that result. You like working with your hands to construct test apparatus and mixing things together to see what happens. You know which brands of toothpaste, paint, computer monitor, and ice cream are the best, and you can explain in detail the specific physical reason why they are the best. Things that other people miss or find mundane you take immense interest and curiosity in, and find complexity and nuance where others don’t.
Nothing is more satisfying than getting concrete answers, and you enjoy learning from and teaching others to achieve clarity and knowledge for all. You have a practical outlook on how to get things done and move a project forward. You’re usually the one that solves the toughest problems, and you do so by being creative, efficient, and persistent. You have the perfect mix of operational, analytical, and people skills. You are a problem solver.
