Job Description

Senior Machinist

Shift: 1st Shift | 8:00 AM – 5:00 PM

Position Overview

We are seeking an experienced Senior Machinist to set up and operate a variety of conventional and numerically controlled machining equipment to produce precision and complex components. The ideal candidate will have hands-on experience with tight-tolerance machining, precision inspection equipment, machine setups, and blueprint reading .

This position works with limited guidance in a team environment and requires the ability to follow established manufacturing processes while making appropriate machine adjustments to consistently produce quality parts.

Key Requirement – Tight-Tolerance Experience

The hiring manager is specifically looking for candidates who have experience machining and inspecting parts to tight tolerances of .003" or better , with the position requiring precision inspection capabilities involving tolerances of less than .0005" .

Candidates should be prepared to provide the tightest tolerance they have personally machined and consistently held.

Key Responsibilities

• Set up and operate multiple production machines, including conventional and CNC equipment.

• Perform machining operations such as cutting, shaping, drilling, grinding, forming, and deburring.

• Perform rework operations as required to bring components into specification.

• Set up and secure work using standard fixtures and established work-holding methods.

• Install and adjust cutting tools based on material type, machine requirements, and established processes.

• Determine and adjust feeds, spindle speeds, and depth of cut to produce quality parts.

• Work from engineering blueprints, sketches, planning sheets, route sheets, specifications, and verbal instructions.

• Read and interpret machining drawings and manufacturing documentation.

• Operate and work with equipment such as:

  • OD, ID, profile, and surface grinders

  • CNC lathes

  • Wire EDMs

  • Broaches

  • Manual machining equipment

• Work with fixtures, arbors, vises, chucks, carriers, collets, and other work-holding/clamping systems.

• Deburr precision and complex machined components and features.

• Inspect finished and in-process components for dimensional and visual conformance.

• Use precision inspection equipment including:

  • Micrometers

  • Calipers

  • Height gauges

  • Indicators

  • Bore gauges

  • Surface finish comparators

  • Other precision measurement equipment

• Use magnification equipment, including microscopes when required, to identify surface damage or defects.

• Perform visual inspections for burrs, damaged surfaces, and other machining defects.

• Accurately complete required shop documentation, job travelers, inspection records, time reporting, and electronic manufacturing records.

• Perform statistical process control (SPC) activities as required.

• Routinely maintain machining equipment to support cleanliness, accuracy, and reliability.

• Handle raw materials, semi-finished components, and finished parts using appropriate carts, hoists, lifts, or other material-handling equipment.

• Participate in Lean manufacturing initiatives and identify opportunities to improve productivity, quality, and cost.

• Follow all company safety, quality, and manufacturing procedures and maintain a clean and organized work area.

• Perform other related responsibilities as assigned.

Required Qualifications

• Minimum 3 years of related machining experience .

• Demonstrated ability to perform machine setups with limited guidance.

• Experience operating conventional and/or CNC machining equipment.

• Strong ability to read and interpret blueprints, specifications, route sheets, and manufacturing instructions .

• Experience machining to tight/close tolerances .

• Ability to use precision inspection equipment such as micrometers, calipers, indicators, gauges, and comparators.

• Working knowledge of machine-shop mathematics, including basic trigonometry .

• Understanding of feeds, speeds, depth of cut, tooling, and work-holding.

• Ability to work independently while contributing effectively within a team environment.

• Ability to accurately complete production, inspection, and electronic manufacturing documentation.

• Ability to apply Lean manufacturing concepts and identify process improvements.

• Strong verbal, written, and interpersonal communication skills.

• Ability to use job-specific software and employee self-service systems.

Preferred / Strongly Desired Experience

Candidates will be especially competitive if they have experience with:

• Precision or aerospace machining

• Tight-tolerance components

• CNC setup and operation

• OD/ID/profile/surface grinding

• Wire EDM

• Broaching

• Manual machining

• Complex mechanical components

• Precision inspection and dimensional verification

• SPC

• Lean manufacturing

• Engineering drawings and close-tolerance specifications
