The Senior Machining Technician is a master-level contributor responsible for independently programming, setting up, and operating complex CNC and manual machines to produce tight-tolerance aerospace structural and mechanical components. This role plays a critical part in quality assurance, process optimization, and mentoring junior machinists. The technician collaborates with engineering and manufacturing leadership to support new product introductions (NPIs), tool design, and continuous improvement in high-reliability aerospace manufacturing environments.
Key Responsibilities:
Independently set up and operate CNC mills, lathes, and other machining centers to fabricate complex aerospace components from metal and composite stock
Read and interpret detailed blueprints, GD&T, and CAD/CAM data to execute precise machining operations
Program CNC machines using G-code or CAM software (e.g., Mastercam, Fusion 360, NX CAM) as needed
Perform in-process and final part inspections using high-precision instruments (e.g., CMM, micrometers, bore gauges)
Identify machining anomalies and recommend or implement corrective actions to improve performance and part quality
Mentor junior and mid-level technicians; provide training on advanced setups, tooling, inspection, and machine optimization
Participate in design-for-manufacturability (DFM) reviews and contribute feedback to engineering on part features, tolerances, and tooling requirements
Drive improvements in machining productivity, cycle time, tool life, and quality yield
Support first article inspection (FAI), nonconformance investigations (NCRs), and root cause corrective actions (RCCA)
Ensure compliance with all safety, quality, and regulatory requirements (AS9100, ISO 9001, NADCAP, etc.)
Key Focus Areas:
High-complexity machining for aerospace hardware (structural, flight, propulsion, and tooling components)
Advanced CNC programming, machine setup, and precision inspection
Leadership in shop floor process control, mentoring, and continuous improvement
Cross-functional collaboration on tooling design, FAI/NPI, and quality assurance
Qualifications & Skills:
Education:
High school diploma or GED (required)
Advanced technical training, apprenticeship, or associate degree in machining/manufacturing technology (strongly preferred)
Experience:
8–15+ years of machining experience in aerospace, defense, or similarly regulated precision manufacturing industries
Proven experience in CNC setup and operation, including multi-axis machining and close-tolerance work
Demonstrated involvement in process development, troubleshooting, and technical mentorship
Technical Skills:
Expertise in CNC controls (e.g., Fanuc, Mazak, Siemens, Okuma) and CAM software
Deep understanding of GD&T, material behavior (aluminum, titanium, Inconel, composites), and thermal effects in machining
Skilled in inspection tools and methods, including surface finish analysis and CMM programming
Knowledge of ERP systems, digital work instructions, and quality control software
Soft Skills:
Strong leadership, communication, and mentoring capabilities
Excellent problem-solving and critical thinking under time-sensitive conditions
Continuous improvement mindset with a focus on safety, quality, and throughput
Able to interface with engineering, quality, and program management teams professionally
