• Assist with job staging, material handling, and movement of parts using forklift/mobile equipment
• Provide feedback on design for manufacturability and propose process improvements

• Communicate clearly and proactively with team members, engineers, and leadership to share progress, flag issues early, provide solutions, and keep projects moving efficiently.
• Demonstrate flexibility to support extended work hours or workweeks as needed to meet critical project deadlines or business priorities.
• Support and mentor junior fabricators; be a go-to technical resource

• Willingness to take feedback and adapt to a high-performance team culture
• Availability for overtime and occasional weekend work (7:00 am–3:30 pm core hours)
• U.S.-based only. No relocation assistance
• Bonus Points For
• Experience with Inconel or pressure-rated weldments
• Experience with laser welding (wire and fusion) and similar productivity improvement processes
