R&D Validation and Process Engineer, MaterialsLocation: Huntington Beach, CA (Onsite)
Compensation: $105,000 - $115,000 (Depending on Experience)
About the RoleAs an R&D Validation and Process Engineer, Materials, you will play a critical, hands-on role in validating 3D printing materials, optimizing complex resin processing parameters, and ensuring seamless end-to-end performance across SprintRay's digital dentistry ecosystem. Working in close collaboration with materials scientists, workflow optimization specialists, hardware engineers, and validation teams, you will establish rigorous validation protocols for next-generation dental photopolymers, evaluate material properties from bench scale through production, and author comprehensive process validation reports based on thorough hands-on testing. This is a fully on-site position ideal for a data-driven engineer with a strong background in materials characterization, additive manufacturing process optimization, and technical report writing.Key Responsibilities- Design, execute, and document comprehensive validation protocols (IQ/OQ/PQ) for new 3D printing materials, photopolymer resins, and complete post-processing workflows.
- Evaluate mechanical, thermal, and dimensional properties of printed parts to ensure consistency, accuracy, and compliance with clinical standards.
- Optimize 3D printing process parameters (e.g., exposure profiles, layer thickness, light intensity) and post-curing regimes to maximize photopolymer performance, dimensional accuracy, and print reliability.
- Collaborate closely with cross-functional workflow, validation, and hardware teams to support scale-up, tech transfer, and process optimization for chemical manufacturing and resin bottling lines.
- Lead design of experiments (DOE) to investigate resin stability, print reliability, and failure modes across different hardware platforms.
- 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
- Perform rigorous hands-on laboratory testing and author detailed process validation reports, technical documentation, and standard operating procedures (SOPs) to support product qualification.
Required Qualifications- Bachelor's degree in Materials Science, Chemical Engineering, Manufacturing Engineering, or a related discipline (or equivalent practical experience).
- 3+ years of experience in materials validation, process engineering, quality assurance, or product development within polymer synthesis or additive manufacturing.
- Strong understanding of photopolymerization chemistry, resin formulations, and additive technologies.
- Hands-on experience operating SLA/DLP 3D printers, post-processing hardware, and materials testing equipment (e.g., tensile/flexural testing, viscosity, UV curing analysis).
- Proven expertise in conducting hands-on materials testing and drafting thorough, publishable process validation reports and technical specifications.
- Knowledge of polymer and materials science principles, including structure-property relationships.
- Familiarity with dental materials, additive manufacturing, or medical device products is preferred.
- Experience supporting process development, optimization, and continuous improvement initiatives.
- Strong analytical and problem-solving skills with a methodical, data-driven approach.
- Excellent organizational and time management skills, with the ability to manage multiple priorities.
- Exceptional attention to detail and commitment to producing high-quality, accurate work.
- Exceptional technical writing, data analysis, and cross-functional communication skills, with a track record of effective collaboration across workflow, validation, and R&D engineering teams.
- Demonstrated ability to work both independently and collaboratively in a fast-paced R&D environment.
