Senior Machinist - CNC & Navy-Grade Parts

Job Description

Oceaneering’s 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.

Responsibilities

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

• 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.

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

• Inspect, measure, and verify machined features using OD/s, 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.

• 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.

• High School Diploma/GED .
• Minimum eight (8) years’ experience machining complex submarine, aerospace, defense, nuclear, or similarly critical components in a precision or defense manufacturing environment.
• Ability to develop new programs or machining strategies across manual and/or CNC machines.
• Ability to perform advanced setups, optimize tool paths, and improve setup instruction sheets on multiple machines.
• Ability to operate both CNC and manual machine tools, develop fixturing and processes, and troubleshoot issues without supervision or guidance.
• Able to read, interpret, and evaluate advanced blueprints, drawings, GD&T, and technical specifications for manufacturability without supervision or guidance.
• Ability to perform multi-axis machining operations (e.g., 4-axis or 5-axis mills) as applicable.
• Demonstrated working knowledge of shop math (e.g. convert between decimals and fractions, adding and subtracting decimals and…
