Plumbing Journeyman

About the role
EJC Engineer LLC is hiring a licensed plumber — master or journeyman — trained and confident on every component of a plumbing system installation for new construction. You will rough-in, set, test, and finish complete systems on commercial and residential projects across southern New Hampshire, northern Massachusetts, and southern Maine. We run organized, well-coordinated jobs and we expect the same back: clean work, accurate layout, and pride in what gets buried in the wall.

What you will install
•     Underground sanitary, storm, and vent systems — cast iron, PVC, and ABS DWV.

•     Above-ground DWV with proper grade, support, expansion joints, and cleanouts.

•     Domestic water distribution — copper (sweat, press), PEX, CPVC; backflow preventers, mixing valves, PRVs.

•     Natural gas and propane piping — black iron, CSST; pressure testing and certification.

•     Floor drains, floor sinks, cleanouts, trap primers, hub drains, and grease waste systems.

•     Water heaters and boilers — gas, electric, and indirect; expansion tanks, recirculation pumps, and venting.

•     Plumbing fixtures — commercial and residential; ADA-compliant rough-in and final set.

•     Medical gas, lab waste, or specialty piping a plus, not required.

•     Insulation, hangers, seismic restraint, firestopping, and penetrations per code.

•     Hydrostatic, air, and final code testing; punchlist completion and turnover.
