You will collaborate closely with R&D, eCommerce, Manufacturing, Regulatory, Quality, Legal, and Supply Chain to ensure materials are robust, compliant, scalable, and ready to support global commercialization.
Role expectations
- Lead material selections, evaluation, and qualification across a range of polymer‑based material systems used in Align products.
- Own material strategy and execution for new product introduction (NPI), regional launches, and sustaining activities.
- Independently manage multiple parallel material workstreams with high visibility and business impact.
- Lead dental materials assessments (e.g., composites, adhesives, polymers) to support product global launch and meet regional requirements.
- Define testing strategies and deliver clear data-driven technical recommendations to cross‑functional stakeholders.
- Support medical device packaging materials and systems as part of overall material ownership.
- Design, evaluate, and optimize medical and consumer packaging for performance, manufacturability, and sustainability in accordance with ISO 11607 and ASTM/ISTA standards.
- Design and perform standard and customized polymer characterization (thermal, mechanical, rheological, spectroscopic) and long-term reliability evaluations.
- Define and approve material specifications; author validation protocols and reports documentation per Design Control and QMS requirements.
- Lead collaboration with internal teams and external partners to evaluate, qualify, and scale sustainable materials and packaging solutions globally.
- Support chemical-compliance and biocompatibility evaluations to ensure regulatory readiness and provide data for product filings.
- Translate complex test results into clear technical reports, risk assessments, and strategic recommendations that guide product and business decisions.
- Mentor and coach engineers and technicians to strengthen experimental design, data integrity, and sustainability best practices across the materials function.
