Senior Materials Developer

OPT Industries builds a proprietary additive manufacturing platform producing micron-resolution polymer structures. We're looking for a senior material scientist to lead the development of high-performance photopolymer materials, someone who can independently run a program from formulation strategy through customer qualification, and who is hands‑on at the bench daily.

• Lead formulation development of photopolymer resin systems for demanding industrial applications, owning programs from initial strategy through customer qualification
• Design and execute systematic formulation studies: monomer and oligomer selection, additive and filler systems, photo‑initiator packages, and iterate rapidly against performance targets
• Perform hands‑on materials characterization across thermal, mechanical, and rheological properties; interpret results and translate them into formulation decisions
• Balance competing material requirements: printability, cure behavior, thermal performance, and mechanical properties, to arrive at manufacturable solutions
• Optimize resin systems for OPT's 3D printing processes, working closely with our print and process engineers
• Work directly with customer engineering teams to align on specifications, present data, and support qualification programs.

• Master or PhD in Chemistry, Polymer Science, Materials Science, or related field
• 3+ years of industry experience with photopolymer or thermoset formulation
• Proven ability to independently drive a materials program end to end
• Experience with DLP/SLA printing is a plus
