A day in this role

As the senior technical anchor on our Maintenance Operations team, you’ll be the go-to expert for complex equipment issues across production and facilities. Your morning may start triaging a furnace atmosphere control alarm, continue with auditing a calibration record for NIST traceability, and move into optimizing a PM task list in the CMMS for our compressed air network. When a critical machine trips a fault mid-shift, you’ll be first on scene—diagnosing controls, PLCs, VFDs, motor circuits, and mechanical subsystems—restoring uptime safely and quickly. Between events, you mentor Technicians I & II, verify work order quality, and drive reliability improvements with data-backed root cause analysis.

This position reports to the Maintenance Manager and partners daily with Production, Engineering, Quality, and Operations to sustain safe, compliant, and efficient manufacturing.

What you’ll own

• Lead hands-on diagnosis and repair of mechanical, electrical, pneumatic, hydraulic, and control systems for production and facility assets; document all work in the CMMS.
• Independently service and troubleshoot furnace systems, compressed air and gas infrastructure, and facility electrical systems.
• Administer the calibration program: maintain schedules, perform calibrations, audit documentation, and ensure full traceability of instruments and standards.
• Act as escalation point for Technicians I & II; provide real-time guidance during complex failures and serve as Qualified Trainer; maintain training records.
• Enforce LOTO and confined space entry compliance across shifts; promote safe maintenance practices, PPE use, machine guarding, and environmental/GMP requirements.
• Continuously improve PM task lists in the CMMS; refine job plans to enhance reliability and performance.
• Review and approve work order completions by Technicians I & II for accuracy and quality; coach for continuous improvement.
• Lead root cause investigations on recurring failures; implement and verify corrective actions that prevent reoccurrence.
• Serve as first responder for critical equipment issues; determine repair strategy, escalation needs, and resources.
• Support equipment installations, commissioning, facility upgrades, and maintenance improvement projects.
• Champion reliability through condition monitoring, failure analysis, Lean, 5S, and continuous improvement initiatives.
• Participate in off-shift and on-call coverage as required.

Background that sets you up for success

• High school diploma or GED required; technical certificate, Associate’s degree, or equivalent experience in Industrial Maintenance, Manufacturing, or Mechanical Systems. Combinations of education, technical training, military service, apprenticeships, and relevant experience considered.
• Completion of a state-accredited journeyman or technical school program—or equivalent formal training with proven field proficiency—strongly preferred.
• 3+ years in industrial maintenance within medical device, aerospace, or other precision manufacturing environments.
• Experience spanning preventive/corrective maintenance, troubleshooting, and maintenance-driven continuous improvement.
• Background in regulated manufacturing (GMP, ISO, medical device, aerospace) preferred; exposure to installations/commissioning and capital or facility projects is a plus.

Technical depth

• Expert troubleshooting of mechanical, electrical, pneumatic, hydraulic, and automated equipment.
• Hands-on expertise with industrial furnace systems: atmosphere control, electrical systems, thermocouples, high-temperature mechanicals.
• Advanced compressed air knowledge: distribution, leak detection, dryers, pressure regulation, efficiency analysis, major repairs.
• Calibration know-how: NIST traceability, documentation rigor, scheduling, and meticulous recordkeeping.
• Read/interpret electrical schematics, mechanical drawings, manuals, and technical documentation.
• Electrical diagnostics at the panel level; troubleshoot PLCs and VFDs, motor controls and sensors, including 3-phase systems.
• Strong CMMS capability: PM program management, work orders, asset history, reporting, and documentation quality.
• RCA/RCM fluency: perform failure investigations and implement corrective actions to boost reliability.
• Working knowledge of Lean, 5S, CI, and reliability-centered maintenance principles.
• Proven mentor/trainer for maintenance technicians.
• Solid grounding in LOTO, PPE, machine guarding, and safe maintenance practices.

Preferred qualifications

• Licensed Electrician or comparable formal electrical certification.
• PLC programming or advanced controls troubleshooting (Allen-Bradley, Siemens, or similar).
• Regulated manufacturing experience (GMP, ISO, aerospace, or medical device).
• Exposure to additive manufacturing or other precision production technologies.
• Experience directing outside vendors and contractors.
• Forklift, crane, or aerial lift operator certifications.

Physical demands

• Lift, carry, push, and pull up to 50 lbs with or without reasonable accommodation.
• Stand, walk, bend, and climb ladders; perform physical work for extended periods.
• Use hand and power tools; manipulate parts and hardware with dexterity.
• Work in manufacturing environments with heat, noise, chemicals, and airborne particles while wearing required PPE.
• Safely access equipment above shoulder height, below waist level, and in confined/restricted areas as trained and authorized.

Perks

• PTO and paid holidays
• Medical, dental, and vision plans
• 401(k) retirement plan
• Fringe benefits
• Paid parental leave
• Onsite perks like food and coffee

Proficiencies
