Field Welder

About the role

As a Field Welder on the Field Operations team, you will perform the hands-on welding that turns engineering drawings into working nuclear hardware — in our Austin factory and at project sites in the field. You will weld stainless steel pressure vessels, piping, structures, and prototype hardware to approved procedures, working day-to-day alongside field engineers, machinists, and test technicians.

This role is a great fit for a skilled welder who wants to work on complex, high-reliability hardware, hold tight quality standards, and support installation and commissioning wherever Aalo builds. You will weld to procedure, help troubleshoot fit-up and joint issues at the bench, and contribute wherever needed to keep the build moving.

Responsibilities

• Perform manual and mechanized welding — primarily GTAW and GMAW — on stainless steel pressure vessels, piping, structures, and assembly fixtures in the shop and in the field.
• Weld to approved Welding Procedure Specifications (WPS) and maintain compliance with applicable codes such as ASME Section IX and AWS D1.6.
• Read and interpret mechanical drawings, weld symbols, and joint details, and set up parts for repeatable, high-quality welds.
• Prepare joints, control fit-up and alignment, and manage preheat, interpass, and shielding conditions to meet procedure requirements.
• Support orbital and mechanized GTAW where applicable, including setup and monitoring of automated welding systems.
• Work directly with field engineers, machinists, and assembly technicians to build, modify, and rework hardware, test rigs, and prototypes on tight timelines.
• Diagnose and resolve weld defects and fabrication issues at the bench; support root-cause analysis with the welding engineering team.
• Support NDE activities (RT, PT, UT, PAUT) and rework nonconformances to close out inspection findings.
• Maintain organized records of welds performed, procedure and material traceability, deviations, and inspection results.
• Support on-site installation, commissioning, and field repair at reactor and test facilities, with travel as required.
• Maintain and pursue welder qualifications and certifications as the team and project scope grow.

Basic Qualifications

• Completion of a welding program, trade certification, or equivalent hands-on welding experience.
• 3+ years of hands-on welding experience, including GTAW on stainless steel.
• Ability to read and interpret mechanical drawings, weld symbols, and joint configurations.
• Experience welding to written procedures (WPS) and holding tight quality standards.
• Basic familiarity with powered and manual tools.
• Strong ownership mindset, attention to detail, and clear communication; comfortable working with ambiguity in a fast-iterating environment.
