Pump Mechanic/Maintenance Technician

Twin Rivers Technologies.•Quincy, MA

6d•Onsite

About The Position

Performs skilled mechanical maintenance in an oleochemical refinery environment to ensure safe, reliable, and efficient operation of process equipment and plant systems. The work includes inspection, troubleshooting, repair, precision alignment, installation, and overhaul of rotating and stationary equipment, including centrifugal and positive displacement pumps, valves, heat exchangers, steam systems, and ASME pressure vessels. The role is comparable to an industrial mechanic or millwright in a continuous-process manufacturing facility and requires independent judgment, technical competence, limited supervision, and strict adherence to safety, environmental, and quality standards. The technician performs maintenance in accordance with plant safety programs, including Lockout/Tagout (LOTO), confined-space entry, hot-work permitting, fall protection, and energy isolation. Precision work includes laser and dial-indicator alignment, flange assembly, steam-tracing installation, rigging, and manual machine-shop operations. The position supports plant outages and shutdowns, which may require extended hours or shift assignments. The regular schedule is Monday through Friday, 6:00 a.m. to 2:30 p.m.; schedules may periodically rotate and include holidays and weekends.

Requirements

High school diploma or GED.
At least 3 years of industrial mechanical maintenance experience in a refinery, chemical plant, power plant, or similar heavy-industrial environment, or completion of a recognized Industrial Maintenance, Millwright, or Mechanical Technology program.
Demonstrated experience repairing centrifugal pumps and performing precision alignment using laser tools or dial indicators.
Working knowledge of bolted-flange assembly practices.
Experience operating manual machine-shop equipment, including a lathe and milling machine.
Ability to read and interpret mechanical drawings, P&IDs, and equipment manuals.
Proficiency with precision measurement tools, including micrometers, calipers, and dial indicators.
Working knowledge of steam systems and steam traps.
Ability to perform rigging tasks safely.
Working knowledge of LOTO and refinery safety procedures.
Ability to perform duties involving frequent walking, standing, lifting, pushing, pulling, and carrying objects up to 50 pounds; climbing stairs and ladders to heights of 120 feet; lifting equipment up to and exceeding 40 pounds; and turning valves, moving handles, and working overhead.
Ability to perform work in all weather conditions, extreme cold and heat, and potentially confined spaces, using required personal protective equipment.
Ability to complete mandatory training for periodic potential exposure to hazardous chemicals or conditions.

Nice To Haves

Formal Millwright or Industrial Mechanic apprenticeship.
NCCER Industrial Maintenance or Millwright certification.
OSHA 10 or OSHA 30 certification.
Confined Space Entry and Fall Protection training.
Experience working on shell-and-tube heat exchangers and ASME pressure vessels.
Experience in an oleochemical, chemical, or refinery environment.

Responsibilities

Perform work in compliance with plant safety programs, including LOTO, confined-space entry, hot-work permitting, fall protection, and energy-isolation procedures.
Identify and mitigate job hazards through Job Safety Analyses and established procedures; recommend stopping activities that jeopardize personnel safety, equipment integrity, or plant operations.
Diagnose, disassemble, inspect, repair, and reassemble centrifugal and positive displacement pumps, mechanical seals, and bearing systems.
Perform precision shaft alignment using laser alignment tools and dial indicators; install and torque couplings, bearings, and rotating assemblies to applicable specifications.
Remove, inspect, repair, and reinstall process valves; replace gaskets and assemble bolted flanges using appropriate torque sequencing and bolt loading.
Assist with piping-system modifications and mechanical installations.
Install, repair, and maintain steam-tracing systems, including tubing bending, flaring, steam-trap installation, and condensate-system troubleshooting.
Maintain and repair shell-and-tube heat exchangers, including bundle removal, inspection, and reinstallation.
Support maintenance of distillation columns, hydrolysis towers, distillation systems, ASME-coded pressure vessels, and refinery process towers.
Support inspections, internal-entry preparation, and reassembly of large vertical vessels.
Perform basic rigging for moving equipment and inspect and use slings, shackles, and lifting devices safely.
Perform precision measurements and operate manual machine-shop equipment, including lathes, Bridgeport-style milling machines, drill presses, and broaching tools.
Drill, tap, fabricate, and modify components; machine and fit keyways and shafts for rotating-equipment repairs.
Perform preventive and corrective maintenance on hydrolysis, distillation, fractionation, separation, utility, and logistics systems.
Document work accurately in the computerized maintenance management system (CMMS).
Recommend improvements to maintenance procedures and reliability practices, and keep tools, rigging equipment, and shop areas in safe working condition.
Participate in major plant outages, shutdowns, turnarounds, and TRT's annual shutdown; work extended hours or shift assignments as required.
Provide support services such as lubrication, equipment inspections, and general mechanical troubleshooting.
