O2 Treehouse is a custom treehouse construction company that combines modern engineering with traditional craftsmanship. They are seeking a versatile Carpenter/Fabricator to work primarily in their wood shop, building treehouse components and providing occasional field support.
At roughly $38/hr, this posting sits about 29% above the $29/hr median for welder fabricator jobs across California — toward the top of a $25–$36/hr middle band drawn from 58 postings with published pay. Put another way, it pays more than about 84% of the comparable postings we have wage data for. Pay that far above local median usually comes attached to something: a harder cert requirement, travel, night shift, or overtime that isn't really optional. Worth establishing which before you accept.
