Compensation: $90,000 - $105,000 annually (depending on experience)
About the RoleAs an R&D Engineer, Materials, you will play a hands-on role in developing, testing, and scaling advanced photopolymer resins that power SprintRay's 3D printing ecosystem. Working closely with scientists, engineers, and manufacturing teams, you'll help bring next-generation dental materials from concept to production through laboratory experimentation, data-driven problem solving, and cross-functional collaboration. This is a fully on-site role ideal for someone with a passion for materials science, innovation, and delivering high-quality solutions for digital dentistry.Key Responsibilities- Conduct research to develop new 3D printing resins and photopolymerization formulations for digital dentistry.
- Manufacture, characterize, and test polymer resins to define requirements for next-generation dental products.
- Scale up R&D formulations and provide continuous support to resin production and manufacturability improvements.
- Optimize resin settings and establish materials standards to meet quality, usability, and print consistency requirements.
- Prepares R&D documentation and reports by collecting, analyzing, and summarizing information.
- Maintain the cleanliness and organization in workshop area.
- Follow safety rules and procedures constantly.
- Collect data and perform statistical analysis on user experience to drive product features and reliability improvements.
- Monitor top product failure modes and provide manufacturing knowledge to QA to reduce production costs.
- Maintain a functional Mechanical workshop and maintain inventory level of the R&D department.
Required Qualifications- Bachelor's degree in Materials Science, Chemical Engineering, Manufacturing Engineering, or a related discipline (or equivalent practical experience).
- 3+ years of experience developing, manufacturing, characterizing, and testing polymer or photopolymer resin systems.
- Strong understanding of photopolymerization chemistry, resin formulations, and additive technologies.
