Job Summary
About Cellsense:
Cellsense transforms algae and cellulose into sustainable embellishments and beaded fabrics for the fashion jewelry and beauty industries. Our proprietary material replaces sources of microplastics and heavy metal pollution while offering designers a wide range of brilliant colors clarities and properties such as fluorescence. Our manufacturing system cuts lead time for customized beaded products from weeks to days by eliminating expensive tooling and tedious manual labor. Cellsense is VC-backed and we are currently scaling our process while running paid pilots with industry partners with inbound interest from 55 companies. You would be joining at a particularly exciting stage of growth.
The Role:
Were looking for a Materials Scientist to lead formulation and chemistry development at Cellsense as we scale. Youll work across our biopolymer systems to improve material clarity surface finish durability and processing behavior and support the transition of formulations from lab to manufacturing.
As a key member of a small collaborative team youll work closely with our founder engineering team and technical advisors. This role offers meaningful ownership and direct impact on the development and deployment of Cellsenses next-generation materials.
Responsibilities:
- Design and iterate on biopolymer formulations to support Cellsenses scale-up.
- Apply DOE to evaluate fillers plasticizers crosslinking chemistry and drying conditions against defined aesthetic and performance targets.
- Optimize rheology for automated material deposition and film formation.
- Develop practical methods to characterize dimensional stability mechanical performance and wet/thermal stability.
- Convert validated formulations into reproducible batch procedures material specifications and QA/QC standards.
- Work closely with our founder and mechanical engineer to scale formulations into repeatable production
What Were Looking For:
- MS or PhD in Materials Science Polymer Chemistry Chemical Engineering or a related field with 2 years of industry experience; candidates with a BS and 3 to 5 years of relevant industry experience are also welcome.
- Hands-on formulation experience with polymers hydrogels or composites not just characterization: you have blended modified and scaled materials yourself with a record of taking projects from concept to completion.
- Working knowledge of biopolymers crosslinking mechanisms and phase behavior.
- Ability to design and execute experiments analyze data and document methods for reproducibility and scale-up; strong organizational skills and attention to detail.
- Self-motivated problem solver who thrives in a startup environment and works effectively across disciplines.
- Proactive and collaborative communicator who is excited to see work move from lab to real products and contribute to Cellsenses mission.
