Develop and refine 3D printing processes, including print parameters, curing protocols, and surface finishing techniques.
Investigate post‑processing methods such as cleaning, thermal curing, UV exposure, and surface treatments to enhance final part performance.
Apply knowledge of polymer chemistry and structure–process–property relationships to improve material performance.
Support design verification and regulatory documentation for new materials.
Conduct hands‑on lab work to develop, test, and refine process workflows.
Collaborate with design, manufacturing, clinical, marketing, regulatory, and legal teams to ensure product readiness.
Contribute to intellectual property generation through innovative material and process solutions.
Mentor junior engineers and lab technicians by sharing technical expertise and best practices.
Work with other engineers, designers, and managers to solve technical problems and develop product roadmaps.
Manage multiple projects, ensuring timely execution and alignment with development goals.
What We’re Looking For
PhD in Polymer Chemistry, Materials Science, or a related field.
8+ years of experience in material research, with an emphasis on polymer structure–property relationships and characterization.
Proficiency in polymer characterization techniques: mechanical testing, thermal analysis, rheology.
Effective communication skills for cross‑functional collaboration and technical reporting.
Preferred: 3–5 years of experience in 3D printing technologies, especially resin‑based systems (e.g., SLA, DLP).
Experience in dental or medical device product development.
Familiarity with coating processes, post‑processing, and surface treatments for 3D printed parts.
Must‑Have Experience
2+ years in photopolymer material development.
2+ years in product development, preferably in medical devices.
Pay Transparency If provided, base salary or wage rate ranges are the range in which Align reasonably expects to set a candidate’s pay for the posted position. Actual placement depends on individual skills and experience level and total compensation and equity across team members.
Benefits Family Benefits: Align offers employees and eligible dependents medical, dental, and vision plans (with a Health Savings Account option for some plans). Additionally, employees receive:
