Maintenance Mechanic

Job Title: Maintenance Mechanic
Job Description
The Maintenance Mechanic will focus primarily on welding, sanitary welding, and fabrication while also performing industrial maintenance duties in a yeast and fermentation manufacturing environment. This role maintains, troubleshoots, and repairs production equipment such as fermentation vessels, utilities, rotating equipment, and downstream separation and packaging assets. The position supports safe, efficient, and compliant operations under GMP and food-safety standards, minimizing downtime and ensuring consistent product quality.
Responsibilities

• Perform welding, sanitary welding, and fabrication work, including MIG, TIG, and stick welding, with a focus on stainless and sanitary piping and components.
• Transition from welding and fabrication tasks to general maintenance duties as needed to support production operations.
• Perform preventive, predictive, and corrective maintenance on fermentation and downstream equipment, including fermenters/bioreactors, transfer pumps, positive displacement pumps, valves, homogenizers, decanters/centrifuges, heat exchangers, air compressors, vacuum systems, and packaging lines such as conveyors, wrappers, and fillers.
• Service utilities critical to yeast production, including steam and boiler systems, condensate, clean and plant water, CIP supply and return, process air, CO₂ venting and abatement, and chilled or glycol loops.
• Inspect, align, and rebuild rotating equipment such as bearings, seals, couplings, and gearboxes, and perform precision shaft alignment and balancing.
• Support CIP (Clean-in-Place) and SIP (Steam-in-Place) readiness by verifying spray ball coverage, valve actuation, temperature, time and flow targets, gasket integrity, and leak tightness.
• Diagnose mechanical failures using root cause techniques and replace worn parts such as seals, gaskets, belts, chains, and sprockets, while correcting piping and mechanical fit-ups to meet 3A and ASME sanitary standards where applicable.
• Read and interpret P&IDs, OEM manuals, schematics, exploded views, and equipment specifications to plan and execute maintenance and repair work.
• Collaborate with controls and electrical engineering teams on issues involving PLCs, VFDs, sensors, and instrumentation, applying basic electrical and mechatronic aptitude.
• Use precision measuring tools, rigging and hoisting equipment, alignment tools, and torque procedures to complete mechanical work safely and accurately.
• Apply strong safety practices including lockout/tagout, confined space protocols, proper use of PPE, and safe handling of chemicals and caustics used in CIP processes.
• Document maintenance activities and follow maintenance procedures while using a CMMS to record work orders, parts usage, and equipment history.
• Support operations in a food and fermentation manufacturing setting, adhering to GMP and food-safety requirements and maintaining a clean, compliant work area.
• Work overtime as needed, including some weekends and Sundays, to support production demands and respond to urgent maintenance needs.

Essential Skills

• At least 3+ years of experience as an industrial or mechanical maintenance technician in food and beverage, fermentation, chemicals, or process manufacturing.
• Proficiency with pumps, valves, pneumatics, hydraulics, conveyors, gearboxes, steam systems, and heat exchangers.
• Hands-on experience performing preventive, predictive, and corrective maintenance on production and utility equipment.
• Experience with sanitary and aseptic piping, tri-clamp fittings, gaskets, and basic sanitary welding or fitting.
• Proficiency in MIG, TIG, and stick welding, with the ability to perform sanitary welding and fabrication on stainless steel and process piping.
• Ability to read and interpret P&IDs, mechanical drawings, OEM manuals, schematics, exploded views, and equipment specifications.
• Comfort using a CMMS to follow and document maintenance procedures and work orders.
• Hands-on skills with precision measuring tools such as calipers and micrometers, as well as alignment tools and torque procedures.
• Basic rigging and hoisting skills for moving and installing equipment safely.
• Strong safety track record including lockout/tagout, confined space awareness, appropriate use of PPE, and safe chemical handling for CIP processes.
• Physical ability to lift up to 50 lbs, work in wet, outdoor, or warm environments near CIP and steam systems, climb ladders, and stand for extended periods.
• Basic electrical troubleshooting capabilities, including work with 24VDC sensors, proximity switches, solenoids, and VFD parameter checks.

Additional Skills & Qualifications

• Experience in yeast or fermentation operations, including fermenters, aeration systems, and CIP/SIP cycles.
• Prior experience in a food manufacturing environment regulated by FDA or similar standards.
• Experience with boilers and cooling towers, including knowledge of steam traps and condensate return systems.
• Boiler operator experience or license.
• Exposure to ammonia refrigeration systems or chilled-water systems and awareness of process safety management (PSM) principles.
• Welding and fabrication experience with TIG welding on stainless steel and sanitary welds, and familiarity with basic machining.
• Collaboration experience with controls and electrical engineering teams on PLCs, VFDs, sensors, and instrumentation.
• Certifications such as OSHA-10 or OSHA-30, Confined Space, Aerial Lift, Forklift, Lockout/Tagout, and First Aid/CPR.
• Experience working in GMP, food-safety, or highly regulated production environments.
• Ability to adapt to changing priorities and support multiple maintenance tasks in a dynamic production setting.
