Supply Chain Operations Specialist

Sixone’s mission is to enable a world where blended plastics products can be circularly recycled back into existing supply chains instead of being sent to landfill. Sixone is a leading technology startup company developing advanced recycling technologies for blended plastics and plastic-based products. The technology applies process digitalization and advanced analytics to build a recycling system to enable efficient plastics recycling.

Our goal is to revolutionize the economics of recycled materials through innovative processing and materials technologies.

Sixone is looking for a Supply Chain & Operations Specialist to own the execution of our core operational systems and workflows. This role reports directly to the Senior Manager of Strategy & Operations and is responsible for bringing operational plans to life — managing our ERP, supply chain, logistics, and inventory functions day-to-day and ensuring nothing falls through the cracks.

You’ll be the person who makes things happen. You own the execution, keep stakeholders aligned, and build the processes that make our operations reliable and scalable. This is a great fit for someone who’s highly organized, comfortable working across teams, and energized by turning plans into results.
