$30 - $40 per hour | San Diego, CA | On-site | Permanent

Founded more than two decades ago and based in San Diego, we are a locally operated precision manufacturing company specializing in low-volume, high-quality prototyping and machining. We serve sophisticated industries such as aerospace, defense, automation, energy, healthcare, homeland security, and X-ray inspection. Our capabilities span milling, turning, tooling, fixtures, fabrication, welding, CAD support, design consultation, mechanical assembly, and product verification, allowing us to help customers move complex concepts from drawing or model to finished component.

• Work on custom, technically challenging components rather than repetitive, high-volume production
• Machine a broad range of materials, including aluminum, stainless steel, engineering plastics, copper, brass, and titanium
• Gain exposure to prototype, short-run, tooling, fixture, and precision manufacturing projects
• Join an experienced, locally operated San Diego manufacturing team
• Work directly from customer drawings, models, and specifications
• Opportunity to contribute beyond basic machine operation as your capabilities grow

• Set up and operate CNC mills and/or CNC lathes to manufacture prototype and low-volume precision components.
• Review blueprints, CAD models, setup documentation, and work instructions before beginning production.
• Select and install appropriate cutting tools, holders, fixtures, work holding, and raw materials.
• Establish work offsets, tool offsets, and machine reference points.
• Load, verify, and safely execute CNC programs.
• Perform first-piece and in-process inspections using calipers, micrometers, height gauges, indicators, and other precision measuring equipment.
• Make tool-offset and wear-compensation adjustments to maintain dimensions throughout the machining process.
• Identify setup, tooling, work holding, material, or program-related issues and communicate necessary corrections.
• Machine components from aluminum, stainless steel, plastics, and other specialty or exotic materials.
• Perform multiple setups while responding to changing priorities in a fast-paced job-shop environment.
• Deburr and visually inspect completed components before routing them to the next operation.
• Maintain accurate production, inspection, material, and job-traveler documentation.
• Assist with fixture development, process improvements, and machining recommendations when appropriate.
• Maintain machines, tools, measuring equipment, and work areas in clean and serviceable condition.
• Follow all quality, safety, and established manufacturing procedures.

• High school diploma or equivalent; technical machining education, apprenticeship training, or relevant certifications are preferred.
• Minimum 3 years of CNC machining experience involving independent setup and operation.
• Hands-on experience setting up CNC mills and/or CNC lathes; candidates capable of working across both are strongly preferred.
• Experience in a fast-paced, high-mix, low-volume job shop is highly preferred.
• Ability to interpret blueprints, dimensional callouts, tolerances, and basic GD&T.
• Experience selecting tooling, establishing offsets, setting work holding, and completing first-piece inspections.
• Proficiency with standard precision measuring equipment.
• Ability to make offset adjustments and basic edits at the machine when required.
• Experience machining multiple materials, including aluminum and stainless steel.
• Proven ability to work from drawings or models and produce components to customer specifications.
• Ability to manage multiple jobs, setups, and changing production priorities without sacrificing quality.
• Must be able to work independently and troubleshoot routine machining problems.

• Prototype or short-run machining experience
• CNC mill and CNC lathe experience
• Tool-and-die, jig, fixture, or custom work holding experience
• Experience machining plastics, copper, brass, titanium, or other specialty materials
• Familiarity with aerospace, defense, medical, automation, or similarly regulated precision work
• Experience performing basic G-code or conversational program edits
