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’re looking for a Process Design Engineer who will play a critical role in the process design, development, and engineering of Ambercycle’s first-of-a-kind commercial plant. This role will preferably be performed onsite at our LA Headquarters, but remote candidates will also be considered. You will work in collaboration with the R&D, Engineering and Technology teams to directly contribute to plant design, equipment design, creation of engineering deliverables, and realization of Ambercycle’s commercial plant. You will make process and design improvements which can be applied at this and future facilities. You will work on capital projects from basic engineering all the way through startup and operations for Ambercycle's commercial plants. You will do so in collaboration with both internal engineering teams, and external engineering partners. You will transfer laboratory experiments to full-scale commercial processes and be involved in every technical stage of the project lifecycle. 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.
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, including engagement with and oversight of equipment vendors, EPC firms, and consultants.
