CAD Engineer
Arcessio is the AI layer for manufacturing intelligence and execution. Our AI agents turn part data into optimal manufacturing decisions and procurement-ready workflows, then execute product through our network of qualified suppliers.We are looking for a CAD Engineer who lives in the geometry — someone who can open a STEP file, immediately see how the part should be made, and translate that judgment into rules, test cases, and feedback that make our agents smarter.This role sits between engineering and product: part of the day is hands-on CAD work supporting customer parts, and part is working with our ML and full-stack engineers to encode manufacturability knowledge into the product.What you'll doReview, repair, and prepare customer CAD models (STEP, STL, IGES, native formats) for analysis and quoting.Apply design-for-manufacturing judgment across CNC machining, sheet metal, injection molding, and additive processes — and document that judgment so it can be automated.Build and curate the ground-truth datasets and test cases our manufacturability agents are evaluated against.Work directly with customers and suppliers to resolve geometry, tolerance, and GD&T questions that block production.Partner with ML and full-stack engineers to turn recurring manual checks into automated agent behavior.Must-havesU.S. citizenship (required). This role works with sensitive government Controlled Unclassified Information (CUI) and is subject to government contract requirements.In San Francisco, in person — 3–4 days/week at our co-working space (Friday remote optional).4+ years of hands-on CAD and mechanical design experience in a production environment.Fluency in at least one major CAD package (SolidWorks, Onshape, NX, CATIA, Fusion 360) and comfort moving between formats.Strong grasp of GD&T, tolerance stack-ups, and how process choice drives cost and lead time.Clear communication — you can explain a manufacturability tradeoff to an engineer, a buyer, or a supplier.Nice to haveScripting experience (Python especially) or CAD API/automation work.Hands-on shop floor time — machining, sheet metal, or 3D printing.Exposure to defense, aerospace, robotics, or other regulated hardware programs.CompensationCompetitive salary plus equity, benchmarked against well-funded startups.
