Is a CAD/3D internship right for you?

Are you passionate about performant graphics, optimizing geometric computations on the web, novel 3D algorithms to unsolved problems, intuitive and user obsessed 3D UI and visualizations or design for manufacturing concepts? These are just some of the types of work and innovation the CAD/3D team leverages to accelerate our company’s growth and success. Join a team where we build tools and experiences that drive impact in our product quality, delight our customers, push operational efficiency and automation past the industry defined limits.

About Dandy

Dandy is a fast-growing health-tech startup transforming the $400B dental industry through groundbreaking advances in Generative AI and robotics. We reached our first $100M in revenue in under two years—faster than companies like Uber, Slack, and Shopify—and our rapid growth has continued over the past two years. The company is backed by top-tier investors including Primary, Greenoaks, and General Catalyst.

We’ve built the largest ML and CAD engineering teams in dentistry, drawing exceptional talent from leading organizations such as Google DeepMind, Amazon, and Waymo. Our full-stack engineering teams tackle complex challenges across platform architecture, supply chain optimization, and SaaS product development. Research is core to our culture, and our team includes authors of award-winning work, including ICML Best Paper.

At Dandy Engineering, you will

• Tackle frontier problems in 3D dental prosthetic design– consuming and refining the outputs of generative AI models or perception layers.

  • We promise that your work will be way beyond prompt engineering and wrapping around 3P APIs: you’ll scope algorithms, design, iterate and deploy real solutions that drive meaningful commercial impact at scale.

• Design and implement advanced computational geometry algorithms that power rapid, accurate design of custom 3D prosthetics for manufacturing.

• Build advanced optimization algorithms to orchestrate a complex supply chain with millions of interdependent components, enabling speed, reliability, and automation.
