· Travel to client sites or job locations as required (occasional, up to a moderate percentage of time depending on project needs).

Required qualifications

· 3–5+ years of practical experience performing orbital welding on high-purity sanitary piping and vessels; biotech/pharma, food & beverage, or related clean-process environments preferred.

· Demonstrated proficiency with orbital TIG welding equipment and process parameters; ability to interpret WPS/PQR, drawings, and P&IDs.

· Knowledge of or experience with ASME BPVC Section IX weld qualifications and ASME BPE guidelines; familiarity with FDA/cGMP requirements and cleanroom protocols.

· Ability to work in cleanroom environments, with appropriate PPE, and maintain stringent contamination-control practices.

· Strong attention to detail, hand-eye coordination, and manual dexterity; good problem-solving and communication skills.

· High school diploma or equivalent; technical/structural welding training or an associate degree in welding technology, industrial maintenance, or related field preferred.

· Certification or demonstrated qualification as an orbital welder is highly desirable.

Preferred qualifications

· Prior experience with surface finishes and passivation processes relevant to high-purity systems.

· Experience with non-destructive testing methods (dye penetrant, pressure tests) and leak testing procedures.

· Valid welding certifications (AWS or equivalent) and/or ASME/BPE-specific welder qualifications.

· Ability to read and interpret quality documentation and produce precise weld reports.

Physical requirements

· Ability to stand, bend, and reach for extended periods; lift/move items up to 50 lbs as needed.

· Ability to work in confined spaces or tight joints and in controlled environmental conditions.

· Willingness to wear personal protective equipment (PPE) as required.

Work environment

· On-site fabrication and assembly in a manufacturing shop and at client facilities.

· Potential exposure to noise, fumes, and high-purity cleaning chemicals; strict adherence to safety and contamination-control practices is required.

· Cleanroom and hygienic-piping environments; emphasis on cleanliness, traceability, and documentation.

Compensation and benefits

· Competitive base salary, commensurate with experience.

· Overtime opportunities, and comprehensive benefits (health, dental, vision, 401(k) with company match, paid time off, etc.).

· Paid training and opportunities for professional development and welder-certification advancement.

How to apply:

· Submit a resume and a brief cover letter outlining relevant orbital welding experience and certifications.

· Include any documentation of weld qualifications or ASME/BPE-related credentials if available.
