You will join a tight-knit team where people enjoy working together and often stay for many years, reflecting a supportive and stable work culture.

The work takes place in an industrial machine shop that is greasy and dirty but well sectioned and organized, with designated areas for different functions. Welders are grouped in the same area of the shop, working alongside a team of approximately 7–9 welders, each with their own areas of focus, fostering collaboration and specialization. The role follows a daytime schedule, typically Monday through Friday, with shifts running from either 7:00 a.m. to 3:30 p.m. or 6:00 a.m. to 2:30 p.m. The environment involves regular use of welding and fabrication equipment, including MIG and TIG welding machines, band saws, drill presses, grinding tools, and various hand and layout tools, in a setting that requires comfort with industrial conditions and appropriate work attire suitable for a dirty shop.
