CNC Machinist

2nd shift position. 2 to 10:30 pm

Our Marine Services Division (MSD) is seeking a highly skilled Inside Machinist with CNC programming, setup, and machining expertise to support the manufacturing of complex, critical submarine components in a low-volume, build-to-print environment. This role requires mastery of machining principles, precision measurement, and blueprint interpretation. Unlike high-volume “widget” machining shops, our work consists of one-off and non-repeat builds with tight tolerances, exotic alloys, and high-quality standards that directly support the U.S. Navy submarine fleet.

This role does not require travel but may require overtime.

Responsibilities

CNC Programming & Setup 

• Review, edit, and optimize CNC programs (lathe and mill) using G-code and CAM platforms. 
• Set up, align, and secure workpieces, fixtures, and tooling on CNC and manual machines. 
• Conduct first-article runs and validate programs to ensure dimensional accuracy and repeatability. 

Machining Operations 

• Perform the setup and operation of a wide range of equipment including lathes, mills, grinders, saws, and related shop machinery. 
• Machine complex components from materials such as HY-80, HY-100, stainless steel, Inconel, and other submarine-grade alloys. 
• Select the correct speeds, feeds, tooling, accessories, and cutting methods to achieve required tolerances and surface finishes. 
• Perform complex machining operations with minimal supervision, using both CNC and manual equipment as required. 

Blueprint, Technical, and Work Document Interpretation 

• Read, interpret, and execute machining work using complex blueprints, drawings, manuals, GD&T callouts, and technical work documents. 
• Lay out workpieces, measure and mark reference points, and plan machining processes for one-off components without existing procedures, work instructions, or examples. 

Precision Measurement & Documentation 

• Inspect, measure, and verify machined features using OD/ID micrometers, height gauges, depth gauges, calipers, verniers, dial indicators, lay-out tools, and other precision metrology equipment. 
• Accurately record measurements, readings, and inspection data to ensure compliance with critical tolerances. 
• Work closely with Engineering, Quality, and Planning to resolve machining issues and ensure successful first-time quality. 

Quality, Safety, and Workmanship 

• Adhere to stringent submarine and Navy quality standards, including tight tolerances, high-accuracy fits, and critical surface finishes. 
• Follow all company, OSHA, and NAVSEA safety and cleanliness requirements. 
• Support continuous improvement in tooling, fixturing, machining methods, and program efficiency.

Supervisory Responsibilities

• This position has no supervisory responsibilities.

Reporting Relationships

• Reports to Production Manager.

Qualifications

Required

• High School Diploma/GED
• Minimum five (5) years’ experience machining complex submarine, aerospace, defense, nuclear, or similarly critical components in a precision or defense manufacturing environment. 
• Demonstrated proficiency in programming, reviewing, or editing CNC programs (lathe and mill). 
• Ability to perform advanced setups, optimize tool paths, and improve setup instruction sheets.
• Ability to operate both CNC and manual machine tools without supervision or guidance. 
• Ability to perform multi-axis machining operations (e.g., 4-axis or 5-axis mills) as applicable.
• Able to read and interpret advanced blueprints, drawings, GD&T, and technical specifications without supervision or guidance. 
• Demonstrated working knowledge of shop math (e.g. convert between decimals and fractions, adding and subtracting decimals and fractions, basic trigonometry used for layout and measurements, etc.).
• Ability to perform First Article Inspections and resolve dimensional issues to meet and exceed quality standards.
• Demonstrated knowledge and proficiency in machining practices for tight-tolerance, critical components. 
• Demonstrated proficiency using precision measuring instruments and accurately documenting measurements. 
• Ability to work independently from minimal instructions and drive work through completion. 
• Must be a U.S. citizen who is not a dual citizen of any other country.

Desired

• Experience with exotic alloys and challenging machining conditions. 
• Familiarity with NAVSEA or military specifications. 
• CAM software experience (Mastercam, SolidWorks, etc.). 
• Strong troubleshooting and root-cause problem-solving skills.

Knowledge, Skills, Abilities, and Other Characteristics:

• Demonstrates high attention to detail and quality craftsmanship. 
• Strong communication skills with a collaborative mindset.
• Ability to collaborate effectively with individuals in other departments, such as Quality or Engineering.
• Adaptable and resourceful — able to plan work and think critically in a one-off production environment. 
• Willingness and ability to train less experienced Inside Machinists to support a culture of continued learning and growth.
• Prioritizes and models safety culture and assists in reviewing cleanliness of work area.
