Staff Process Development Engineer Jobs in California

Job Description
Company Overview:
Plastics have become indispensable for nearly every major industry, but conventional plastics impose an unsustainable burden on the environment. Plastic production currently accounts for 8% of global oil and gas use and nearly 5% of GHG emissions. More than 250 million tons of plastic waste accumulates annually, the vast majority of which will persist for centuries. ReSource's proprietary technology will produce the first bioplastic that is made from truly sustainable feedstocks and outperforms incumbent materials without the environmental burden or health risks. We are commercializing an industrially scalable process for producing FDCA, which is a naturally occurring chemical that serves as a replacement for the petrochemical monomer PTA used to make polyesters such as PET. Polyester represents a >$100B industry, with applications spanning packaging, bottles, and fibers. Polyesters made using FDCA have superior gas barrier, thermal, and mechanical properties compared to the petrochemical incumbents, which translates into better performance with less material, including increased shelf life for perishable goods. They are also 100% recyclable and degrade much faster than conventional polyester if released into the environment. Beyond polyesters, FDCA is a platform molecule that can be used to make a wide range of other polymer and specialty chemicals. Past efforts to commercialize such products have been hampered by the high complexity and cost of the manufacturing pathways chosen to make FDCA, all of which use edible sugars as raw materials. In contrast, ReSource produces FDCA from CO2 and inedible biomass and removes two thirds of the conventional process steps, resulting in dramatically reduced production cost that enable rapid scale-up and high-volume applications. Bioplastics made using ReSource FDCA have the potential to eliminate >250 Mton yr-1 GHG emissions.
The company is in Oakland, CA and was founded on technology developed at Stanford University. Backed by leading investors including Khosla Ventures, Fathom Fund, Chevron Technology Ventures, and Mitsubishi Gas Chemical, we are currently preparing to commence pilot and demo-scale production. To date, ReSource has raised >$25M, including nearly $9M in R&D grants from the Department of Energy and National Science Foundation.
Position Overview: We are seeking an experienced and hands-on Process Engineer to join our growing team as we scale from pilot to demonstration-scale production. The ideal candidate combines strong technical fundamentals in process design with practical, hands-on experience operating and troubleshooting physical equipment, and thrives in the fast-paced, resource-conscious environment of an early-stage technology startup.
