Reports:  Reports to Foam Manager.  No direct reports to supervise.

The RCO Engineering team is looking for a skilled Foam NC Machinist with 3–5 years of experience to join our dynamic prototype and production team. This role is critical for manufacturing high-precision foam components, patterns, and mold supporting the aerospace and general production group in a fast-paced manufacturing business.  They will be responsible for the setup, operation, and optimization of 3- and 5-axis CNC machines in a fast-paced environment where priorities shift between rapid R&D prototyping and low-rate production runs. The successful candidate must be a self-starter having a sense of ownership of their projects, and highly organized with a willingness to grow within the foam group.

Core Responsibilities

• Setup & Operation: Create setup/tooling sheets to assist operators with setup on Thermwood routers
• Manage production run jobs with operators,
  • Answering questions and ensuring quality requirements are met.
• Prototype to Production: Transition seamlessly from executing "one-off" experimental parts to managing low-volume production batches with high efficiency.
• Programming & G-Code: Read and interpret complex blueprints, CAD models, and CAM files. Perform "at-machine" G-code edits to optimize toolpaths for foam-specific feeds and speeds.
• Quality Inspection: Use precision instruments (calipers, micrometers, height gauges) to perform first-article and in-process inspections, ensuring parts meet tight tolerances.
• Collaborative Design: Provide real-time Design for Manufacturing (DFM) feedback to engineers to improve part producibility and solve machining challenges.
• Tooling & Fixturing: Design and fabricate custom work-holding fixtures and jigs necessary for complex foam geometries.
• Maintenance: Perform daily machine maintenance and maintain a clean, organized workspace

Requirements

• Experience as a CNC Programmer:
  • Minimum of 3 years working as an NC machinist
    • Large-format CNC routers and milling centers
  • Minimum of 1 year working with Foam
• Knowledge of Visi programming software
• Experience in production and/or prototype settings
• Strong organizational skills.
• Proficient in MS Office (Outlook, Word, Excel).
• High School Diploma or GED
