The ideal candidate is highly proficient with Autodesk Fusion 360 CAM, understands tight-tolerance machining, and can work closely with fabrication and welding teams to improve quality, fit-up, and production efficiency.
Key Responsibilities
CNC Programming & Setup
- Develop, modify, and optimize CNC programs using Autodesk Fusion 360 CAM
- Create toolpaths for milling, drilling, facing, contouring, pocketing, and related machining operations
- Simulate and verify programs prior to production
- Select appropriate tooling, feeds, speeds, and machining parameters
- Maintain CNC program revisions and supporting documentation
- Set up and operate CNC mills and/or lathes
Precision Machining
- Machine components from 304/316L stainless steel, aluminum, and specialty alloys
- Perform first-piece and first-article inspections
- Adjust offsets, tooling, and machining parameters to maintain dimensional accuracy
- Produce tight-tolerance components and precision sealing surfaces
- Machine weld-prep features including bevels, grooves, and fit-up surfaces
- Support rework and repair machining as required
Weld Shop & Fabrication Support
- Produce fixtures, jigs, and tooling used in TIG and orbital welding
- Partner with welders and fabrication teams to improve fit-up and reduce distortion
- Support machining requirements for UHP/high-purity gas delivery systems
- Identify opportunities to improve throughput and repeatability
Quality & Compliance
- Read and interpret engineering drawings, blueprints, GD&T, and specifications
- Verify dimensional tolerances and surface finish requirements
- Use precision measuring equipment including calipers, micrometers, and height gauges
- Maintain material and work-order traceability
- Follow applicable ISO 9001 and customer-specific quality requirements
Continuous Improvement & Safety
- Identify opportunities to reduce setup time, scrap, unnecessary motion, and other process waste
- Participate in Kaizen and continuous-improvement initiatives
- Standardize tooling, setups, and programming practices
- Support SQDC objectives: Safety, Quality, Delivery, and Cost
- Maintain a clean and organized work area in accordance with 5S standards
- Follow all CNC equipment, tooling, cutting-fluid, and material-handling safety procedures
Required Qualifications
