[Remote] Senior Process Engineer, CNC Machining

Note: The job is a remote job and is open to candidates in USA. Dandy is transforming the dental industry with innovative technology and is seeking a Senior Process Engineer specializing in CNC Machining. This role involves developing next-generation milling processes for custom dental prosthetics, optimizing workflows, and integrating automation systems to enhance manufacturing efficiency. Responsibilities • Own CNC process development for patient-specific dental components — from prototype to scaled production • Design and validate machining workflows for multi-axis mills (3-, 4-, and 5-axis) that achieve micron-level precision, excellent surface finish, and high throughput • Integrate automation systems (robotic loading, part handling, in-line probing, vision inspection) into CNC workflows to achieve 24/7 'lights-out' operation • Optimize toolpaths, feeds, speeds, and cutting strategies for complex geometries and challenging materials (zirconia, titanium, PMMA, and wax) • Develop and document process standards — tool libraries, fixture designs, validation protocols, and SPC control plans — to ensure reproducibility and compliance • Collaborate with R&D and design teams to improve manufacturability of patient-specific geometries while maintaining clinical fidelity • Lead root cause analysis and yield improvement across machining cells using structured problem-solving and statistical tools • Work cross-functionally with software, automation, and quality teams to build reliable, automated manufacturing lines capable of scaling to tens of thousands of custom parts per day • Scout and qualify new technologies — cutting tools, coolant systems, machine architectures, or in-process metrology systems — to push the limits of digital manufacturing • Work with industrial automation vendors to design milling automation solutions Skills • 8+ years of experience in micron-level precision CNC machining, automation, or process development, ideally within medical devices, dental, or other patient-specific manufacturing domains • Deep technical fluency in multi-axis milling (3-, 4-, and 5-axis) — milling strategy development, toolpath optimization, cutting dynamics, and precision fixturing • Experience developing, tuning, or troubleshooting post-processors or control drivers for G- and M-code generation (e.g., Fanuc, Heidenhain, Siemens) • Proven experience integrating automation or robotics into machining workflows (robot arms, part changers, vision systems, or in-line measurement) • Strong understanding of statistical process control (SPC), process validation, and manufacturing scalability • A systems-thinking approach — understanding how design, manufacturing, and inspection fit together in a digital feedback loop • Comfort working in an agile, fast-paced, high-growth manufacturing environment • Experience in dental, orthopedic, or other regulated medical device manufacturing • Familiarity with FDA, ISO 13485, or GMP process validation • Background in machining brittle ceramics or titanium alloys • Exposure to closed-loop manufacturing (e.g., vision feedback for tool wear or dimensional control) • Experience working with automation integrators or designing robotic cells for high-mix / low-volume production Benefits • Healthcare • Dental • Mental health support • Parental planning resources • Retirement savings options • Generous paid time off Company Overview • More than a dental lab—Dandy is a tech-powered, end-to-end solution delivering high-quality, customized restorations at scale. It was founded in 2020, and is headquartered in New York, New York, USA, with a workforce of 501-1000 employees. Its website is Company H1B Sponsorship • Dandy has a track record of offering H1B sponsorships, with 3 in 2025, 1 in 2024, 1 in 2023, 3 in 2022.
