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. Air-travel-compliant form of ID and a valid Driver's License. Preferred Experience Stainless steel TIG (GTAW) experience on pressure-boundary applications.

Current or prior AWS or ASME Section IX weld qualifications. Experience with orbital, mechanized, or robotic welding in a production environment. Experience welding zirconium, titanium, or Inconel, including under inert-atmosphere conditions. Familiarity with NDE methods and interpreting inspection results. Background in nuclear, aerospace, defense, or other high-reliability regulated industries.

Hands-on fabrication experience beyond welding (machining, sheet metal, assembly, rigging). Physical Requirements Comfortable working on the factory floor and in industrial, construction, and remote field environments. Physically fit for duty — capable of lifting up to 50 lbs and standing, climbing ladders, and working for extended periods while wearing PPE.

Willingness to weld at heights, in confined spaces, and in varying weather or environmental conditions when trained and authorized. Willingness to perform sustained hands-on welding, fabrication, and assembly work. What It Takes to Succeed at Aalo We're building technology that will help reshape the future of energy. The pace is fast, the problems are difficult, and the expectations are high.
