CNC Tooling Engineer

About this role

Mach Industries, a defense technology startup, seeks a CNC Tooling Engineer to establish and manage a comprehensive tooling ecosystem for precision manufacturing. You'll standardize tool selection, manage digital tool databases, optimize cutting data, and collaborate across engineering and production to enable rapid scaling from prototyping to high-rate production of autonomous defense systems.

What you'll do

• Own and maintain CNC tool database including records, assemblies, holders, offsets, cutting data, and vendor information
• Standardize tooling across production jobs and CNC machines to reduce variation and improve repeatability
• Build tool assemblies for milling, turning, drilling, boring, threading, and specialty operations
• Define tooling standards for holders, shrink-fit assemblies, gauge length, runout, balance, and inspection requirements
• Coordinate with smart cabinet and vending systems to maintain inventory visibility and consumption tracking
• Analyze tool wear, failure modes, and usage data to reduce cost-per-part and improve tool life

What they're looking for

• CNC machining and tooling selection expertise
• Manufacturing engineering and process optimization
• CAM platform integration and data management
• Tool assembly and holder standardization
• Inventory management and supply chain coordination
• Root-cause analysis for production issues
• RFID, barcode, or tool-identification system implementation
• Materials knowledge (aluminum, steels, stainless, titanium, nickel alloys)

Benefits

• Impact on U.S. national security and defense innovation
• Startup agility within a rapidly growing 220-person company
• Located in Huntington Beach, CA
• High-visibility role owning end-to-end tooling ecosystem
• Opportunity to shape manufacturing processes from ground up

Likely interview questions

• Walk us through your experience standardizing tooling across multiple CNC machines and production environments—what challenges did you face and how did you overcome them?
• Describe a time when tooling issues caused production delays. How did you diagnose the root cause and implement a solution?
