CNC Tooling Engineer

About the role

Mach develops autonomous defense platforms and requires a dedicated engineer to manage the entire CNC tooling ecosystem. You will oversee tool standardization, data management, and process optimization to improve production efficiency and part quality. This is a hands-on position based on the shop floor that requires close collaboration with manufacturing, programming, and supply chain teams.

Key facts

What you'll do

• Manage the CNC tool database, including assemblies, holders, offsets, cutting data, and standard libraries.
• Standardize tooling across all machines and CAM platforms to ensure repeatability.
• Define specifications for shrink-fit systems, gauge length, runout, balance, and coolant delivery.
• Select tools to optimize the balance between cycle time, tool life, surface finish, and cost.
• Integrate tooling data across CAM software, presetters, machine controls, and smart cabinets.
• Oversee inventory levels, including reorder points and consumption tracking.
• Conduct root-cause analysis for machining issues such as chatter, breakage, and dimensional drift.
• Implement RFID or barcode tracking systems and develop training materials for shop floor staff.

Requirements

• 5+ years of experience in CNC machining, tool crib management, or manufacturing engineering.
• Expertise in cutting tools, toolholding, coatings, geometries, and material-specific feed and speed strategies.
• Proficiency in standardizing tooling for milling, turning, drilling, boring, and threading.
• Familiarity with CAM systems, tool libraries, and production workflows.
• Ability to create and maintain technical documentation and standards.
• Capacity to work with urgency in a high-paced manufacturing environment.

Nice to have

• Experience with digital tool management platforms or integrated CAM libraries.
• Proficiency in SQL for database management and reporting.
• Familiarity with Vericut, NCSIMUL, Mastercam, Fusion, NX CAM, ESPRIT, or Hypermill.
• Background in aerospace, defense, propulsion, or UAV hardware manufacturing.
• Experience transitioning high-mix, low-volume production into higher-rate output.

Skills & tools

• CNC tooling and toolholding systems
• CAM software and tool library management
• Inventory control and smart cabinet systems
• Root-cause analysis and process optimization
