You will join a well-established commercial plumbing contractor with a long-standing presence in the Bay Area and a close-knit, family-style culture. The company offers competitive wages and clear growth opportunities, including the potential to move into a foreman role. Employees receive a comprehensive benefits package that includes medical and dental coverage, paid time off starting at one week for the first five years and increasing to two weeks thereafter, seven paid holidays, and three sick days, supporting both professional development and work-life balance.

The company operates from a base in Hayward and focuses on projects within roughly 50 miles of that location, typically keeping jobs within 30–35 miles to reduce long commutes. Current projects are located in Emeryville, the East Bay, and San Francisco, with typical assignments lasting about 1–2 months per job depending on project phase. On-site, you report to a foreman and work alongside teams ranging from 2 to 10 coworkers.

The standard shift runs Monday through Friday from 6:00 a.m. to 2:30 p.m., with flexibility required to start between 5:00 a.m. and 7:00 a.m. depending on the general contractor and job site. A company vehicle is not provided, so you will use your own vehicle to travel to job sites, and standard mileage reimbursement is available when you need to drive to the shop or multiple sites in a single day.

The work is field-based on active construction sites, involving hands-on installation using personal plumbing hand tools and typical commercial construction equipment.
