Job summary

Arc is building electric marine propulsion and powertrain systems in Los Angeles. As a Fabrication Technician on our Fab team, you will turn raw stock into finished, boat-ready components, operating CNC mills, lathes, welding, and general fabrication to meet build schedules.

You will read drawings, work with shop tooling, and support engineers with rapid prototypes. This on-site role demands physical activity and a fast, steady pace for production and R&D builds.

Qualifications

• 2+ years of hands-on experience in metal fabrication and machining in production, prototype, or job shop environments.
• Experience setting up and operating CNC mills.
• Experience with MIG welding on mild steel.
• Ability to read and interpret blueprints, engineering drawings, and basic GD&T.
• Proficiency with precision measuring tools such as calipers, micrometers, and height gauges.
• Experience with shop equipment: bandsaws, shears, press brakes, grinders, and drill presses.
• Comfort shifting between machining, welding, and fabrication work as priorities change.
• Ability to work independently with minimal supervision at a fast but sustainable pace.
• Enthusiasm for boating and clean energy.

Responsibilities

• Set up and operate CNC mills (3 and 5 axis), including programming with CNC lead support.
• Run manual mills and lathes for one-off parts, rework, and secondary operations.
• Fabricate brackets, mounts, enclosures, and structural components from drawings and verbal direction.
• Cut, bend, form, and drill sheet metal, plate, tube, and bar stock.
• Weld and assemble steel, aluminum, and stainless parts using MIG and TIG where needed.
• Deburr, tap, finish, and assemble machined parts.
• Build jigs, fixtures, and shop tooling to speed and repeat builds.
• Inspect parts with calipers, micrometers, and gauges for tolerances.
• Support engineers with rapid prototypes and feedback on DFM.
