POSITION SUMMARY

The CNC Machinist sets up and operates computer numerically controlled (CNC) milling and/or turning equipment to produce precision-machined components in support of Whelan Machine & Tool's defense manufacturing programs. This role is responsible for interpreting engineering drawings, selecting appropriate tooling and work-holding, and executing first-article and production runs to contract requirements, while maintaining the quality, safety, and traceability standards required of a defense supplier.

KEY RESPONSIBILITIES

Setup and Operation

• Read and interpret engineering drawings, blueprints, GD&T callouts, and work instructions to determine machining sequence, tooling, and fixturing.

• Set up and operate CNC mills, lathes, or multi-axis machining centers, including offsets, work coordinates, and tool registers.

• Select, install, and adjust cutting tools, fixtures, and work-holding devices appropriate to material and tolerance requirements.

• Edit or adjust CNC programs at the control (offsets, feeds, speeds) as needed; escalate program-level changes to Manufacturing Engineering.

• Perform first-article inspection and in-process checks using precision measuring instruments (micrometers, calipers, height gauges, CMM as applicable).

Quality and Compliance

• Maintain dimensional accuracy and surface finish within specified tolerances on close-tolerance, aerospace/defense-grade components.

• Complete required inspection records, traveler documentation, and Certificates of Conformance in accordance with quality system procedures.

• Identify and flag nonconforming material or process deviations promptly; support root-cause and corrective-action activities as needed.

• Follow all applicable ITAR, CMMC, and export-control handling procedures for controlled technical data and hardware.

Safety and Equipment Care

• Perform routine machine maintenance, coolant checks, and housekeeping to keep equipment in safe operating condition.

• Follow all plant safety procedures, including lockout/tagout, PPE requirements, and machine guarding protocols.

• Report equipment malfunctions, safety hazards, or near-miss events in accordance with plant reporting procedures.

Qualifications

Required

• High school diploma or equivalent; completion of a machinist apprenticeship, technical program, or equivalent trade certification preferred.

• 2–5 years of hands-on CNC machining experience in a job-shop or precision manufacturing environment; defense or aerospace machining experience strongly preferred.

• Demonstrated ability to set up and run CNC mills and/or lathes with minimal supervision.

• Working knowledge of G-code/M-code and CNC control interfaces (Fanuc, Haas, Mazak, or comparable).

• Proficiency reading blueprints, GD&T, and interpreting engineering revisions.

• Skilled use of precision measuring instruments and basic inspection methods.

• Understanding of metal cutting principles, feeds/speeds, and tooling selection across common aerospace-grade alloys.

• Ability to work independently, manage multiple work orders, and meet production schedules on FFP program deadlines.

PHYSICAL & ITAR REQUIREMENTS

• Access to ITAR-controlled technical data and CUI requires verification of U.S. Person status prior to employment.

• Ability to stand for extended periods on a manufacturing floor; regularly lift and carry up to 35 lbs.; frequent bending, reaching, and use of hand tools; use of appropriate PPE (safety glasses, hearing protection, steel-toe footwear) at all times on the production floor. Reasonable accommodations may be made to enable individuals with disabilities to perform essential functions.

• This position is performed on the Whelan Machine & Tool production floor, a manufacturing environment with exposure to machine noise, cutting fluids, and moving equipment. Standard shift schedules apply; overtime may be required to support production and delivery commitments.
