Dandy is transforming the massive and antiquated dental industry—an industry worth over $400B. Backed by some of the world’s leading venture capital firms, we’re on an ambitious mission to simplify and modernize every function of the dental practice through technology. As we expand our reach globally, Dandy is building the operating system for dental offices around the world—empowering clinicians and their teams with technology, innovation, and world-class support to achieve more for their practices, their people, and their patients.
About The Role
Dandy is looking for a Senior Algorithms Engineer to serve as the multiplying factor in our manufacturing strategy. You will define the strategy for automating complex, high-dexterity tasks that currently require highly skilled technicians.
This role is about 0 to 1 development of novel toolpath and robotic control mechanisms as well as yield boosting optimizations to existing toolpath infra. You will bridge the gap between digital design and physical production, driving a multi-modal (additive + subtractive) workflow that is a top priority for our company’s growth. You’ll be working on the most interesting manufacturing problems in the industry in a high-visibility role where you will be the architect of our competitive edge.
What You’ll Do
- Define the Strategy: Lead the development of toolpath algorithms that serve as the core engine for Dandy’s next-generation dental lab automation.
- Multi-Modal Manufacturing: Build workflows for hybrid production—eg, 3D printing and injection molding, or 3D printing parts and then polishing or milling them back with high precision.
- Robotic Control: Develop novel robotic control mechanisms (6DoF) to automate high-dexterity tasks like polishing and finishing metal and acrylic partials.
- Bridging Software & Hardware: Research and implement toolpath simulation and collision avoidance algorithms to ensure "right-first-time" manufacturing.
- Cross-Functional Leadership: Partner across engineering and operations to transition theoretical robotics into production-ready deployments.
- Problem Solving: Solve the critical, high-impact manufacturing problems that are currently the bottleneck for global scaling.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What We’re Looking For
- Software Engineer / CS Background: You are a software engineer first, with the ability to write production-grade, high-performance C++, python or other language.
- Toolpath & CNC Expertise: Deep, hands-on experience with 5-axis CNC or 6DoF robotic integration. You’ve moved beyond theory and have seen your code move machines in the real world.
- Computational Geometry: Proficiency in fundamental 3D concepts, mesh processing, and algorithms (WASM, WebGPU, or C++ libraries like CGAL/Open CASCADE).
- Simulation Mastery: Experience in toolpath simulation, kinematics, and robotic path planning.
- Problem Solver: A "0 to 1" mindset. You thrive in startup environments and enjoy defining the roadmap rather than just following one.
- Strong Communicator: Ability to explain technical risks and trade-offs to stakeholders while executing on a high-level business strategy.
- Open to Travel: Flexibility to travel frequently (up to 30%), balancing on-site project needs at our Salt Lake City, Dallas and Indianapolis sites
Our Technology
- Languages: C++, TypeScript
- Graphics/Compute: Three.js, WebGL, WebGPU, WGSL
- Platform: WASM / Emscripten, React
- Robotics: ROS, custom 6DoF control stacks, or proprietary toolpath engines.
Bonus Points For
- Startup Experience: You’ve built and scaled systems in a fast-paced environment.
- Multi-Modal Experience: Familiarity with both additive (SLA/DLP) and subtractive (Milling/Grinding) processes.
- Dental or Medical Tech: Experience with digital prosthetic design or medical device manufacturing
- Compliance and Regulatory: Experience with testing paradigms, documentation, compliance concepts common in regulated device manufacturing.
- GPU Optimization: Deep knowledge of HLSL, GLSL, or CUDA for parallelizing geometry processing.
