Location: Valencia, CA 91355 (On-site) Job Type: Full-Time Pay Range: $35 – $45 per hour (based on experience) Shift: Monday – Friday | Day Shift Overtime: As needed based on production demand Experience Level: Senior (7+ years CNC machining & programming experience) Work Authorization: U.S. Person required (ITAR compliance) Why This Role Exists This role exists due to continued growth in aerospace and defense manufacturing programs requiring high-precision prototype and low-volume production components. At H&H Machining Center, this position is critical to producing tight-tolerance, flight-critical parts where quality, consistency, and machining expertise directly impact aerospace and defense program success. The Work You’ll Be Doing In this role, you will set up and operate CNC mills and lathes including 3, 4, and 5-axis machines while programming parts from scratch using Mastercam or Fusion 360. You will machine prototype and low-volume precision components directly from engineering blueprints, ensuring all GD&T requirements are met. You will be responsible for selecting tooling, setting offsets, and establishing setups to maintain process stability and repeatability. You will perform in-process inspection using precision measurement tools including micrometers, calipers, and CMM equipment while maintaining tight tolerances of ±0.0005” or better. You will troubleshoot toolpaths, optimize cutting parameters, and make machine-level adjustments using G-code knowledge as needed. Collaboration with engineering, quality, and other machinists will be required to ensure all parts meet AS9100D standards and customer requirements. Machines, Controls & Software You will work with CNC milling and turning equipment including 3-axis, 4-axis, and 5-axis machines. CNC controls include Fanuc, Haas, and Mazatrol systems. CAM programming is performed using Mastercam (preferred) or Fusion 360, with G-code required for machine-level edits and troubleshooting. Inspection tools include micrometers, calipers, and CMM systems for precision measurement and verification. Materials You’ll Work With Aluminum Steel / Alloy Steel Stainless Steel Titanium Inconel What We’re Looking For Required 7+ years CNC machining and programming experience Strong experience with CNC mills and lathes Ability to program parts from scratch using CAM software Proficiency in Mastercam and/or Fusion 360 Strong blueprint reading and GD&T interpretation skills Experience holding tight tolerances (±0.0005” or better) Familiarity with Fanuc, Haas, and/or Mazatrol controls Experience machining aerospace materials such as titanium and Inconel U.S. Person status required (ITAR compliance) High school diploma or equivalent required Preferred Multi-axis machining experience (4/5-axis) Aerospace or defense machining experience Vocational or technical training in machining or manufacturing Experience working in AS9100D environments Why Machinists Like Working Here Machinists choose H&H Machining Center because the work is technical, challenging, and meaningful within aerospace and defense manufacturing. The shop environment is clean, organized, and equipped with modern CNC machines. Employees work on complex, non-repetitive parts with real responsibility from setup through inspection. The company offers stable long-term employment, strong team collaboration, and opportunities to grow into more advanced machining and programming roles.
