Job Description:
This position is ideal for senior-level R&D engineers
specializing in Simulation and Modeling to join the Process
Modeling team within Product Research Engineering as a Sr. R&D
Engineer - Simulation & Modeling. In this role, you will lead the
development of advanced manufacturing technologies by applying
innovative finite element modeling and machine learning techniques
to optimize and understand additive manufacturing processes. Your
work will directly enhance the production of dental and orthodontic
devices and play a critical role in shaping Align Technology’s
next-generation products and driving future success. Role
expectations • Lead the cutting-edge 3D printing technologies by
leveraging innovative finite element models and machine learning
approaches to optimize and understand the additive manufacturing
process, enhancing the production of dental and orthodontic
devices. • Lead the machine learning projects for orthodontic
system design and manufacturing, from initial data analysis and
model development to optimization, deployment, and ongoing
monitoring, leveraging massive clinical research database. • Lead
the development of a state-of-the-art finite element analysis
(FEA/FEM) platform of orthodontic systems leveraging cutting edge
computational algorithms. • Lead the development of robust methods
for difficult-to-model conditions leveraging advanced commercial
FEA/FEM software. • Work cross-functionally with the software team
to deploy computational models to very large scales, with design
team to integrate model-driven components into the product, with
materials and process team to calibrate physical models, and with
clinical team to run studies for model validation. • Work
independently to develop and evaluate new products/solutions or to
adapt and improve existing ones using computational modeling and
physical experiments. • Design, build, and verify test hardware,
software, and systems as needed. • Define and conduct procedures
for bench top testing to evaluate product performance, including
efficacy, reliability, verification, and validation, as needed. •
Work with clinical team to conduct pilot studies and other
investigations. • Perform and document work in accordance with
FDA/ISO regulations, including test protocols, test results, and
other requirements. • Communicate with professionals in the field
at all levels and transition information into product improvement.
• Provide general engineering support in R&D. What were looking
for • Education: o MS 6 years or PhD 3 years in
Biomedical/Mechanical/Computer Science/Engineering, Statistics or
other related degrees/equivalent work experience. • Experience and
