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. ## Description 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. ## Related Videos - [Rendering Design Software in the Browser at Penpot](https://www.wearedevelopers.com/videos/1353-rendering-design-software-in-the-browser-at-penpot) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [The weekly developer show: Boosting Python with CUDA, CSS Updates & Navigating New Tech Stacks](https://www.wearedevelopers.com/videos/1293-the-weekly-developer-show-boosting-python-with-cuda-css-updates-navigating-new-tech-stacks) - [TresJS a new declarative ThreeJS as Vue components](https://www.wearedevelopers.com/videos/543-tresjs-a-new-declarative-threejs-as-vue-components) - [WeAreDevelopers LIVE – AI, Freelancing, Keeping Up with Tech and More](https://www.wearedevelopers.com/videos/1786-wearedevelopers-live-ai-freelancing-keeping-up-with-tech-and-more) - [WeAreDevelopers LIVE – From JavaScript to WebAssembly, High-Performance Charting and More](https://www.wearedevelopers.com/videos/1794-wearedevelopers-live-from-javascript-to-webassembly-high-performance-charting-and-more) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 129 - Now that's what I call private data!](https://www.wearedevelopers.com/magazine/468-dev-digest-129-now-that-s-what-i-call-private-data) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [WeAreDevelopers Dev Digest Issue 116 - The new search wars…](https://www.wearedevelopers.com/magazine/445-wearedevelopers-dev-digest-issue-116-the-new-search-wars)
