You may be a strong fit if you are an experienced gasfitter who has worked on larger systems, commercial service calls, mechanical rooms, boilers, rooftop units, process equipment, industrial facilities, institutional buildings, or high-demand service environments.

This position is not aimed at entry-level helpers. It is intended for experienced gasfitters, senior technicians, lead hands, and certified tradespeople who can take responsibility for safe, accurate gas work.
