Experience

• Minimum 5–10 years’ experience supervising mechanical and welding works on large industrial or energy projects.
• Proven experience on LNG, oil & gas, petrochemical, or heavy industrial projects is strongly preferred.
• Strong hands-on experience with NDT and Ultrasonic Testing supervision in a construction environment.

Technical Skills

• Strong knowledge of mechanical construction, piping systems, and welding processes.
• In-depth understanding of UT principles, acceptance criteria, and defect evaluation.
• Familiarity with relevant standards and codes such as ASME, EN, ISO, DIN, API.
• Experience with ITPs, NCRs, punch lists, weld tracking systems, and completion documentation.
• Ability to read and interpret mechanical drawings, isometrics, and specifications.

Certifications (Preferred / Advantage)

• Welding Inspector certification (CSWIP, IWI, AWS CWI or equivalent).
• NDT certification (UT Level II or III).
• Safety certification (NEBOSH, IOSH, or equivalent).

Languages

• English required (working language on site).
• German or Spanish language skills are a strong advantage.
