Job summary

laborup is hiring skilled CNC Machinists for a high-mix, low-volume aerospace and defense machine shop in the Boston area. You will manufacture mission-critical, tight-tolerance components for satellites, fighter jets, and more, owning setup through final inspection on advanced 5-axis mills and mill-turn centers.

You will leverage manual machining fundamentals to troubleshoot chatter and optimize tool pressure, select tooling, and build strong workholding strategies.

Qualifications

• 8+ years in precision, tight-tolerance machining.
• Ability to hold tight tolerances on critical features (.0005" / 13 microns).
• Deep understanding of GD&T and true position, parallelism, profile, coaxiality.
• Comfort with complex setups and 30%+ setup time.
• Experience with manual CMMs and first article inspections preferred.

Responsibilities

• Setup, run, inspect, and document results using advanced 5-axis machines.
• Troubleshoot chatter, read chip formation, optimize tooling and offsets.
• Plan tooling, offsets, and workholding to optimize processes.
• Hold tight tolerances from first piece to final run with manual gauges.
• Read and edit G-code/M-code on the floor to maximize throughput.
• Troubleshoot dimensional and machine variables to achieve first article success.
• FAI and CMM programming/operation preferred; Mastercam programming a plus.

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: $30,000
• 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

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).

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