Job Description

Job Summary

We are hiring skilled CNC Machinists to join our high-mix, low-volume aerospace and defense machine shop. In this role, you will machine mission-critical, tight-tolerance components for satellites, fighter jets, helicopters, and beyond.

Our machinists own their work end-to-end, from setup through final inspection, and play a direct role in quality, delivery performance, and continuous improvement.

Why Join Us?

  • Sign-On Bonus Available
  • Unrivaled Equipment: Work with high-precision 3-, 4-, and 5-axis mills and lathes across the highest end brands
  • Fertile Soil for Growth: A highly dynamic job shop setting where you have autonomy over your work
  • Premium Environment: Do high-impact aerospace work in a facility that is modern, clean, and fully air-conditioned.

Compensation

  • Starting pay negotiable and market competitive, and communicated through the interview process.

Shifts

  • Day Shift
  • Monday - Friday

Consistent Overtime

  • 10+ hours / week for those who want it
  • Rarely required for those who don't

Relocation

  • Relocation assistance available

Responsibilities

  • Autonomy: Setup, run, inspect, and document results across our floor, heavily utilizing advanced 5-axis machines and mill-turn centers.
  • Manual Fundamentals: You don’t just rely on the machine; you understand exactly what the cutter is doing. You leverage deep manual machining fundamentals to troubleshoot chatter, read chip formation, optimize tool pressure, and tackle the most complex setups.
  • Strategy & Execution: Select tooling, establish offsets, build bulletproof workholding strategies, and optimize processes.
  • Quality Control: Hold tight tolerances from the first piece through the final run using manual micrometers, indicators, and precision gauges.
  • Programming Mastery: Read, understand, and efficiently edit G-code and M-code on the floor to restore quality and maximize throughput.
  • Problem Solving: Troubleshoot dimensional, tooling, and machine variables on the fly to achieve first-article success on both proven and unproven parts
  • Advanced Quality (preferred): The ability to program/operate CMMs and independently conduct formal First Article Inspections (FAI) is highly preferred).
  • Advanced Programmer (preferred): Experience fully programming from scratch in Mastercam is a plus but not required

Requirements

Qualifications

Required

  • Experience: 8+ years in precision, tight-tolerance machining (more is always welcome).
  • Precision: Proven ability to hold .0005” (5 tenths / ~13 microns) or tighter on critical features, and the manual skills to verify it.
  • Technical Fluency: Deep understanding of complex blueprints and advanced GD&T (true position, parallelism, profile, concentricity, flatness, coaxiality).
  • High-Setup Environment: Comfortable in shops where setup time is 30%+ of the job, frequently handling complex setups with 10+ tools.
  • Quality Background: Deep expertise of manual CMM's

Preferred

  • Aerospace: Strong tenure in Aerospace manufacturing and machining environments
  • Quality Standards: Experience in ISO 9001 or AS9100 shops
  • Equipment Mastery: Extensive experience setting up multi-axis equipment (5-axis mills, mill-turns, and/or multi-axis lathes).

Benefits

  • Medical, dental, vision
  • 401(k) with match
  • PTO
