Mechanical, electrical, hardware, computer, and process. We’ll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.\nSmaller is better. Faster is better. Building it ourselves is better.\nWe believe our team and lab can build anything. We’ve set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we’ll just invent along the way.\nAtomic was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.\nAbout the team\nThe Atomic Semi production team manufactures chip fabs. From deposition and etching tools to lithography and metrology, we are building every tool ourselves. We fabricate the metal parts, operate SMT lines to build PCBAs, and assemble the tools in-house.\nAbout the role\nAtomic Semi is building a new generation of semiconductor manufacturing equipment. We're staffing up our first production facility, and the CNC programmer is the seat that decides how fast we can build them.\nYou own the CAM programs that run our Haas fleet — three UMC-500SS five-axis VMCs, one UMC-750SS, two DS-30Y mill-turn lathes. Today our chassis-mix mill cycle is ~45 min/part. Your year-one target is to drop that to 20 min/part through better toolpaths, smarter fixturing, optimized tool selection, and disciplined process documentation. That single number controls how many cubes we can ship per month.\nResponsibilities\nCAM programming for 5-axis VMC and mill-turn lathe work (Mastercam, Fusion 360, or HSMWorks)\nToolpath strategy on stainless and aluminum semiconductor-grade parts (typical ±0.001\")\nProbing routines for in-process inspection\nTool library, tool-life tracking, and offset management at the Zoller presetter\nPallet-pool lights-out programs for the UMC fleet\nDFM feedback to the design team — \"this would run 30% faster if you opened that radius up\"\nProcess documentation that survives operator turnover\nRequired Experience\n4+ years CNC programming, including 2+ years on 5-axis\nStrong Mastercam, Fusion 360, or HSMWorks fluency\nHaas control native (or comparable Fanuc/Siemens)\nGD&T fluency, comfortable reading drawings to spec\nDocumented track record of taking specific part families from high cycle time to low\nNice-to-have\nTrunnion-mount 5-axis programming\nPallet-pool / lights-out experience (Fastems or similar)\nMill-turn programming on DS-30Y class machines\nSemiconductor, aerospace, or medical-device part background\nMastercam Multi-Axis or HSMWorks Adaptive Clearing certification\nWorking at Atomic Semi\nWe’re an early-stage hardware startup with solid funding, world-class advisors, and a lab/office in San Francisco, CA.\nBenefits: Atomic Semi offers the following benefits, subject to applicable eligibility requirements:\nMedical, Dental, and Vision insurance\nGenerous Paid Time Off inclusive of Holidays and Sick Time\nVisa Sponsorship\nLife and Disability Insurance\nPaid Parental Leave\n401(k) retirement plan\nWeekly Learning & Development opportunities\nCommuter Benefits including Parking and Late Night Uber rides from the office\nLunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and Spindrifts\nWe are an equal-opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.\nExport Control Analysis: This position involves access to technology that is subject to U.S. export controls.
