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 Job
We are searching for an R&D Engineer who will lead the design and fabrication of Ambercycle’s process research systems. You will work in collaboration with the R&D, Engineering, and Technology teams to build bespoke research and pilot scale systems to study, improve, and optimize the Ambercycle process for advanced recycling of textile polymers. You will help design and run experiments on the research systems to debottleneck, further develop, and optimize various unit operations. You will commission, validate, and maintain process research systems made both in-house and with 3rd party vendors and contractors. This will include engagement with and oversight of equipment vendors, fabricators, and other 3rd parties. You will help translate your laboratory and pilot designs to full-scale commercial designs with the Engineering team, and vice versa. The ideal candidate for this role will be driven, confident, and will do what it takes to ensure the successful build and implementation of process systems. You will be involved with senior leaders to optimize and commercially realize our process for the conversion of end-of-life textile materials into brand new goods, as well as grow the portfolio of commercialized Ambercycle products.
