Materials Scientist
Shellworks is on a mission to make plastic waste a thing of the past by creating sustainable materials. The Materials Scientist role involves developing proprietary polymer blends, creating formulations for biodegradability, and conducting material testing to drive innovation in sustainable materials.
Responsibilities
- Drive the development of proprietary polymer blends and additive packages. You’ll be responsible for expanding our core material's scope, successfully hitting commercial performance targets
- You will develop formulations that remain robust and uncompromising during a product’s shelf-life but maintain rapid biodegradability the moment they reach their end-of-life
- Develop a predictive framework that correlates lab-based data to real-world machine settings. Your goal is to eliminate trial-and-error by predicting how materials will behave before they hit the factory floor
- Expand our internal testing suite to connect microstructure analysis (crystallinity, melt stability, etc) to macroscopic failure modes
- Work with suppliers on new materials, including incoming material analysis, testing and qualification
- As a member of a dynamic team, you won’t just stay in your lane. You’ll jump in wherever needed from vetting new sustainable feedstock suppliers to identifying and researching new opportunity spaces
