L4 Staff Welder

The L4 Staff Welder is a senior-level fabrication specialist responsible for precision welding, prototype development, and low-volume aerospace hardware fabrication in a fast-paced R&D and prototype manufacturing environment.

This role supports engineering teams in building flight-critical and mission-critical components using advanced welding techniques and aerospace-grade materials.

Responsibilities:

• Perform precision TIG/GTAW welding on aerospace materials including stainless steel, aluminum, titanium, Inconel.
• Fabricate prototype assemblies, fixtures, tooling, and development hardware from engineering drawings, CAD models, and sketches.
• Read and interpret blueprints, welding symbols, and GD&T requirements.
• Work closely with design, manufacturing, and test engineers to iterate prototype designs rapidly.
• Execute welds capable of meeting aerospace inspection standards including dye penetrant, leak testing, and X-ray inspection where required.
• Set up and operate welding and fabrication equipment including TIG welders, orbital welders, saws, grinders, positioners, and fixturing tools.
• Inspect completed welds for dimensional accuracy, penetration, distortion, and cosmetic quality.
• Repair weld defects and recommend process improvements to improve manufacturability and repeatability.
• Support development and qualification of welding procedures and work instructions.
• Maintain compliance with AS9100, AWS, OSHA, and internal quality standards.
• Mentor junior welders and assist in establishing best practices within the fabrication shop.
• Document fabrication activities, process notes, and prototype deviations accurately.

Required qualifications:

• High school diploma or GED required; technical welding certification preferred.
• 8+ years of precision welding experience in aerospace, motorsports, defense, or prototype manufacturing environments.
• Expert-level TIG/GTAW welding proficiency.
• Experience welding thin-wall tubing and precision assemblies.
• Ability to pass aerospace weld qualification tests in multiple positions and materials.
• Strong understanding of metallurgy, weld distortion control, heat management, and fixturing.
• Ability to read complex engineering drawings and GD&T.
• Experience with aerospace inspection requirements and quality systems.
• Strong communication and collaboration skills in cross-functional engineering environments.

Preferred qualifications:

• AWS D17.1 or equivalent aerospace welding certification.
• Experience with pressure vessels, propulsion systems, fluid systems, or flight hardware.
• Familiarity with vacuum, leak-check, or clean-room fabrication requirements.
• Fabrication or machining familiarity.
• Experience in prototype or R&D environments supporting rapid iteration cycles.
• Ability to support design-for-manufacturing feedback during product development.

Physical requirements:

• Ability to stand for extended periods and lift up to 50 lbs.
• Comfortable working around welding fumes, heat, and fabrication equipment while using PPE.
• Manual dexterity and visual acuity for precision weld work.

Work environment:

• This position operates within a prototype aerospace fabrication shop supporting rapid development programs. Work may involve quick-turn engineering changes, low-volume production, and high-precision hardware fabrication under tight schedules.
