Develop and implement 3D geometric ML and classical geometry algorithms to analyze and generate 3D intraoral scans and teeth. Build data pipelines, train/adapt 3D models, optimize test-time performance, validate robustness, and collaborate with clinicians and product teams to ship applied research into products.
This position is full-time based in Zurich.
We are building the future of digital dentistry. Align Technology has transformed orthodontics and restorative dentistry through Invisalign, the iTero intraoral scanner, and exocad CAD/CAM products used by clinicians in over 100 countries, backed by data from more than 20 million patients. Our Advanced Technology Development (ATD) team in Switzerland is where breakthrough ideas become real products.

Our Advanced Technology Development (ATD) team in Switzerland is where breakthrough ideas become real products.
As a ML Scientist, you will develop and explore advanced methods spanning 3D geometry processing, computer graphics, computer vision, and modern machine learning to solve fundamentally new and unsolved challenges. You will invent new ways to simulate, visualize, and predict dental outcomes, turning raw 3D scans and clinical imagery into intelligent, patient-specific experiences. This is applied research with direct product impact: your prototypes become the features millions of patients rely on.
The Advanced Technology Development team operates as Align’s applied research lab. We are a small, high-impact group of scientists and engineers who work 12-18 months ahead of the product roadmap. You will collaborate daily with clinicians, product managers, and engineering teams across our global offices. We value intellectual honesty, rapid experimentation, and shipping research that changes patient outcomes.
If you are a recent graduate with ambition, curiosity, some relevant reseach work and a desire to make a meaningful impact, we would love to hear from you, even if you don't tick all the boxes of this job description.
Key Responsibilities
