About Us
Ambercycle is a material science company founded in 2015 to create a fashion industry without 'waste'. We're developing and scaling a breakthrough technology to manufacture yarns and fabrics from old clothes, without a sacrifice in quality, rather than from petroleum or new agriculture resources. Our apparel 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. Using our technology, we are fundamentally changing the fashion industry and building the infinite textile ecosystem. For more information, visit
Who You Might Be
You've been building things and taking them apart your whole life. You are thrilled by the prospect of constructing things and watching them work and take great satisfaction in taking concepts into real-world solutions at massive scale, in fact you're wired to do so. You watch YouTube videos of people constructing plants, showcasing process equipment, and doing chemistry experiments. You like working with your hands and really understanding how things work in real life. Overcoming all obstacles to turn whiteboard sketches into breakthrough commercial realities is second nature to you, and you value your ability to get to the heart of an issue and advance a project.
You love efficiency but have a practical outlook on how to get things done and move a project forward. You are respected for your ability to 'make it happen', and people rally around you to turn visions into realities. You have the perfect mix of strategic, operational, analytical, and people skills. You are a clear, confident communicator who loves taking a complicated problem, deconstructing it, and finding + implementing solutions. You are a problem solver.

The ideal candidate will be driven, confident, and will do what it takes to ensure successful commercialization and scale-up of our process technology. This individual will work to ensure effective decision-making and execution of technology development and commercialization. This will include engagement with and oversight of equipment vendors, EPC firms, and consultants. You will be responsible for the technology development, equipment selection, and continual improvement of Ambercycle processes.
