CNC Machinist

CITADEL FEDERAL SOLUTIONS LLC•Annapolis, MD

125d•$25 - $42•Onsite

About The Position

We are seeking an experienced CNC Machinist with proven setup and operation skills on both CNC lathes and CNC mills. This role demands a machinist who is comfortable working with heavy steel and large, precision parts — the kind of work that requires patience, skill, and an uncompromising eye for accuracy. If you take pride in making tight-tolerance parts from tough materials and thrive in a professional machine shop environment, we want to hear from you.

Requirements

Minimum 5 years of CNC machining experience in a production or job shop environment with hands-on setup and operation of both CNC lathes and CNC mills — this is a hard requirement.
Demonstrated experience machining heavy steel and large parts; comfort with large, complex workpieces and the setups they demand.
Proficiency reading and working from engineering drawings including GD&T tolerancing and surface finish callouts.
Working knowledge of G-code and M-code; ability to manually edit programs at the machine control.
Experience with precision metrology tools: micrometers, calipers, height gauges, bore gauges, dial indicators, and surface plates.
Strong understanding of cutting tool selection, speeds and feeds, and tooling strategies for carbon steel and alloy materials.
Ability to safely operate overhead cranes, hoists, and rigging equipment to handle heavy steel components (or willingness to become certified).
Meticulous attention to detail and a strong personal commitment to dimensional accuracy and part quality.
Physical ability to work in a shop environment including standing for extended periods and working with heavy materials.

Nice To Haves

Experience on large-format CNC equipment — horizontal boring mills, large vertical turning lathes (VTL), or multi-axis machining centers.
Familiarity with CAM software such as Mastercam, Fusion 360, or similar for generating and optimizing toolpaths.

Responsibilities

Set up and operate CNC lathes and CNC mills to machine heavy steel and large-scale components to tight tolerances per engineered drawings and specifications.
Write, edit, and optimize CNC programs using G-code and M-code; work with CAM software to generate toolpaths from engineering models and drawings.
Select appropriate cutting tools, tooling inserts, fixtures, and work-holding solutions for each job, with emphasis on heavy steel and large part setups.
Perform precision layout, datum setup, and workpiece alignment using indicators, edge finders, probes, and precision measuring instruments.
Read and interpret engineering drawings, GD&T (Geometric Dimensioning and Tolerancing) callouts, surface finish requirements, and machining tolerances.
Conduct in-process and final inspection of machined parts using micrometers, calipers, bore gauges, CMM, and other precision measurement tools.
Safely rig, lift, and position heavy steel workpieces using overhead cranes, hoists, and material handling equipment.
Perform machine maintenance including lubrication, coolant management, and minor adjustments to maintain accuracy and uptime.
Troubleshoot machining issues including chatter, tool wear, dimensional drift, and surface finish problems, and implement corrective actions.
Coordinate with engineers, shop foreman, and fabricators to ensure machined components integrate correctly with fabricated assemblies.
Maintain accurate job documentation including setup sheets, inspection records, and material certifications.
Follow all shop safety procedures including proper PPE use, crane and rigging protocols, and machine guarding requirements.
Assist in the training and mentoring of junior machinists or apprentices as needed.
