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.

• Review, 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.

• U.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 (Solid Works, 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.

• Scripting 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.

• Competitive salary plus equity, benchmarked against well-funded startups.
