Are you the craftsperson we’re looking for?

  • Do you read blueprints, sketches, and building plans with confidence and translate them into precise layouts for cylinders, plates, and cones?
  • Can you fit, tack, and weld large metal components—inside and out—using SMAW, GTAW, and SAW, and meet the applicable requirements of the American Society of Manufacturing Engineering (ASME) acceptance criteria?
  • Are you comfortable setting up automated welding for interior/exterior seams and switching to precision grinding and deburring with handheld tools?
  • Do you work safely with overhead lifts per contract guidelines and complete engineering test functions without missing a detail?
  • When it’s time to ship, will you wrap and pad, label or stencil crates (destination, weight, product type), add fillers/pads/separators, band crates, verify counts, and close out pack-and-ship Production Orders by cleaning, packing, and tagging components?
