Job Description Job Description Lead Orbital Welder - Stainless Steel & Welding Operations Monday - Friday, Onsite in Tempe, AZ Competitive pay based on experience What You'll Be Part Of This is a highly hands-on technical opportunity for an experienced welder who wants to do more than production welding. You'll play a key role in establishing and growing a stainless-steel welding operation, combining precision orbital and manual
GTAW/TIG
welding with process development, training, quality, and technical leadership. Initially, the majority of your time will be focused on production and project welding. As the operation grows, the role will expand into greater responsibility for technical leadership, process development, workforce training, quality, and day-to-day welding operations. Why This Role Matters You'll help build a sustainable welding capability from the ground up. This includes establishing welding processes and standards, selecting equipment and tooling, supporting qualification activities, training and mentoring welders, and developing scalable workflows that can support increasingly complex stainless-steel projects. The ideal candidate is an accomplished welder with strong technical judgment, initiative, and leadership potential who enjoys building processes and developing people-not simply working within an established welding department. What You'll Do Orbital & Stainless-Steel Welding
Perform high-quality orbital
GTAW/TIG
welding on stainless-steel tubing and piping systems
Set up, program, operate, troubleshoot, and maintain orbital welding equipment and associated tooling
Perform manual
GTAW/TIG
welding when required by project specifications or configuration
Prepare tubing and piping through proper cutting, facing, cleaning, alignment, fit-up, and purging techniques
Produce consistent, repeatable welds that meet customer, engineering, quality, and applicable code requirements
Work with stainless-steel tubing, piping, fittings, valves, and fabricated assemblies
Interpret drawings, isometrics, P&IDs, weld maps, specifications, and fabrication documentation
Inspect completed work and identify weld defects, contamination, fit-up issues, or process deviations
Maintain proper material handling, cleanliness, and contamination-control practices for stainless-steel components Build the Welding Capability
Help establish and grow stainless-steel orbital welding as an internal capability
Assist with selecting and standardizing welding machines, orbital weld heads, power supplies, purge equipment, tooling, consumables, inspection equipment, and supporting infrastructure
Develop repeatable welding practices, setup standards, work instructions, and process controls
Partner with Engineering, Quality, Construction, Manufacturing, and Operations to establish efficient workflows from material preparation through final inspection
Help establish appropriate shop layout, material flow, segregation, cleanliness, and contamination-control practices
Identify opportunities to improve productivity, weld consistency, quality, and throughput
Provide practical input for estimating and project planning, including weld requirements, labor hours, equipment, tooling, and production capabilities Quality & Welding Standards
Support the development and implementation of Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), and welder qualification requirements, as applicable
Maintain compliance with customer specifications, internal quality requirements, and applicable welding codes and standards
Support weld documentation, traceability, weld mapping, inspection records, and qualification records
Work closely with Quality and Engineering to investigate weld failures, defects, and nonconformances and implement corrective actions
Promote a culture focused on weld quality, cleanliness, workmanship, safety, and process discipline Team Development & Leadership
Serve as the technical lead and subject-matter resource for orbital and stainless-steel welding
Help identify staffing needs as welding volume increases
Participate in interviewing and evaluating prospective welders and welding support personnel
Train, mentor, and develop new welders on welding methods, quality expectations, safety requirements, and customer specifications
Assess welder capability and provide hands-on coaching to improve technique and consistency
Help develop a scalable training and qualification program to build a pipeline of qualified welders
Lead by example and remain willing to work alongside the team as the department grows
Take on increasing responsibility for workload coordination, technical leadership, day-to-day welding operations, and team performance as business needs expand Qualifications
Minimum 5 years of professional
GTAW/TIG
welding experience, with significant experience welding stainless-steel tubing and/or piping
Demonstrated hands-on experience with orbital welding equipment and processes
Strong understanding of stainless-steel welding characteristics, shielding and purge gases, heat input, cleanliness, fit-up, and contamination prevention
Ability to consistently produce high-quality welds in a production, fabrication, or construction environment
Ability to read and interpret technical drawings, piping isometrics, weld symbols, specifications, and related documentation
Experience setting up, programming, operating, and troubleshooting orbital welding systems
Strong mechanical aptitude and practical problem-solving skills
Ability and willingness to remain highly hands-on while simultaneously developing processes and people
Demonstrated ability or aptitude to train, mentor, and lead skilled tradespeople
Strong commitment to safety, quality, workmanship, and accountability Nice to Have
Experience with high-purity or ultra-high-purity stainless-steel piping systems
Experience supporting semiconductor, aerospace, chemical-processing, or other high-purity manufacturing environments
Experience with automated or orbital GTAW systems such as AMI or equivalent equipment
Familiarity with ASME Section
IX, ASME B31.3, AWS
standards, or other applicable welding codes
Experience developing or working with WPS, PQR, WPQ, weld maps, weld logs, and traceability documentation
Experience with borescope inspection and weld-quality acceptance criteria
Previous experience as a Lead Welder, Welding Supervisor, Welding Technician, or welding trainer
Experience helping launch or expand a welding, fabrication, or manufacturing operation Key Competencies
Advanced stainless-steel GTAW/TIG and orbital welding knowledge
Strong understanding of tube preparation, alignment, fit-up, purge practices, shielding gases, tungsten selection, weld parameters, and heat control
Ability to troubleshoot welding equipment, tooling, weld programs, and process issues
Strong attention to detail and commitment to repeatable workmanship
Ability to translate welding expertise into standardized processes that can be taught to others
Ability to distinguish between a one-time welding solution and a scalable production process
Effective communication and coaching skills
Strong sense of ownership and initiative
Ability to work effectively across Engineering, Quality, Manufacturing, Construction, and Project Management
Ability to balance production requirements with uncompromising safety and quality expectations Other Expectations
Perform work with a high level of accuracy, accountability, and attention to detail
Follow established welding, quality, safety, and operational procedures
Communicate effectively in English, both verbally and in writing
Work collaboratively with cross-functional teams
Maintain a clean, organized, and safe work environment
Identify and resolve problems proactively without waiting for detailed direction
Comply with all company policies, procedures, and applicable safety requirements Physical Requirements
Ability to stand, bend, kneel, climb, and work in various positions for extended periods
Ability to safely lift and handle welding equipment, tubing, piping, fixtures, and related materials
Ability to work in fabrication, manufacturing, cleanroom, and active construction environments as required
Ability to use appropriate PPE and comply with welding, hot-work, and site-specific safety requirements Success in This Role Success will be measured not only by your ability to produce exceptional welds, but also by your ability to help build a sustainable and scalable welding operation.
Over time, you'll progress from being a primary hands-on technical expert to helping establish standardized processes, develop other welders, increase internal welding capacity, and build a team capable of supporting increasingly complex stainless-steel welding projects. Benefits
