PORTLAND BOLT & MANUFACTURING CO LLC•Portland, OR

2d•$38 - $46•Onsite

About The Position

Portland Bolt, located in Portland’s Northwest Industrial area, is an organization whose business success has been built around the philosophy of providing unparalleled service, quality products, and on-time deliveries. Established in 1912, Portland Bolt manufactures large bolts and fasteners for construction projects worldwide which include high-rise buildings, bridges, power plants, and stadiums. In 2022, Portland Bolt manufactured and shipped over 6.8 million pounds of anchor bolts and construction fasteners to customers in all 50 states, 10 Canadian provinces and territories, and 31 different countries. The Role Portland Bolt runs a mechanically driven shop with production equipment dating from the 1950s–70s. We're looking for a maintenance millwright who can keep it running with minimal supervision — diagnose, repair, rebuild, and fabricate independently. You'll be responsible for maintenance at the facility with real autonomy and a direct line to operations leadership.

Requirements

7+ years industrial maintenance / millwright experience in a manufacturing environment.
Proven track record maintaining and repairing older industrial machinery with limited supervision.
Welding, fabrication, and basic machining competence.
Proficiency with precision measurement, hand and power tools, and blueprint reading.
Able to meet the physical demands of the role (lifting, climbing, standing for extended periods in a shop environment).
Autonomy. You own a problem start to finish without step-by-step direction. This is the single most important trait for the role.
Old-iron fluency. You understand mechanical systems from first principles — comfortable on equipment that predates digital controls, not just a part-swapper.
Self-sufficiency. Your fabrication and machining ability means downtime isn't held hostage by parts lead times.
Judgment. You take ownership of the plant's condition and speak up before things break, not after.

Nice To Haves

Experience in fastener, forging, casting, or heavy-metal manufacturing.
CMMS / ERP maintenance documentation experience (Acumatica a plus).
Hydraulic and pneumatic system rebuild experience.

Responsibilities

Troubleshoot, repair, rebuild, and maintain production machinery — including legacy mechanical equipment where the manuals and OEM support are no longer available.
Diagnose failures independently across bearings, gearboxes, drives, power transmission, hydraulics, pneumatics, and lubrication systems.
Perform precision work — alignment, leveling, fitting to close tolerances — with precision measuring instruments.
Fabricate and machine replacement parts (weld, cut, mill, turn) when parts can't be bought. On equipment this age, this is core, not occasional.
Set and run the preventive/predictive maintenance program; document work in our ERP (Acumatica).
Read and interpret blueprints and schematics — and reverse-engineer when they don't exist.
Rig, move, and install equipment safely; operate overhead cranes and shop equipment.
