Calibration & Maintenance Supervisor

What You'll Do

As the Calibration and Maintenance Supervisor, you will own two mission-critical programs and lead the team that executes them every day.

Team Leadership and Development

• Supervise, schedule, and develop a team of facility maintenance and calibration technicians across shifts.
• Coach technicians, provide ongoing performance feedback, and partner with HR on hiring, onboarding, and corrective action.
• Set team metrics — PM completion rate, calibration on-time percentage, equipment downtime, and response time — and drive continuous improvement against each target.

Calibration Program Ownership

• Own the full calibration program: master schedule, calibration intervals, NIST-traceable reference standards, and out-of-tolerance (OOT) investigations including impact and use assessments on affected product.
• Perform hands-on calibration as needed and maintain all records in LSO's Electronic Quality Management System (Grand Ave.).
• Uphold ALCOA+ data integrity principles and Good Documentation Practices (GDP) across all calibration records.

Preventive Maintenance and Equipment Reliability

• Own the preventive maintenance program: PM schedules, work orders, and equipment reliability for facility and production equipment.
• Troubleshoot and repair equipment to minimize unplanned downtime.
• Manage spare-parts inventory and outside service providers and calibration labs; provide input to the maintenance budget, service contracts, and capital equipment requests.

Qualification, Validation, and Regulatory Readiness

• Oversee IQ and OQ protocols; support equipment commissioning, PQ, and process validation activities.
• Monitor and document controlled environment parameters — temperature, humidity, pressure differential, and particle counts — for cleanroom and controlled areas.
• Represent the maintenance and calibration function during FDA inspections, ISO 13485 audits, and customer or notified-body audits.
• Support nonconformance, CAPA, and change-control processes; develop and maintain SOPs for this business unit.

Safety Leadership

• Champion a safe work environment for the team, owning adherence to lockout/tagout, OSHA and Cal/OSHA requirements, and LSO EHS procedures.
• Ensure all team members wear appropriate PPE for each task and work area.

What You Bring

Skills and Experience

• 5 to 7 years of calibration, metrology, and/or preventive maintenance experience — preferably in an FDA-regulated medical device, pharmaceutical, or other regulated manufacturing environment.
• At least 2 to 3 years in a lead or supervisory capacity, directing the work of other technicians.
• Working knowledge of FDA QMSR (21 CFR Part 820) and ISO 13485:2016.
• Metrology fundamentals: NIST traceability, calibration intervals, measurement uncertainty, gage R&R/MSA, and ANSI/NCSL Z540.
• Proficiency reading mechanical and electrical drawings, schematics, and equipment manuals; hands-on skill with calibration instruments (gage blocks, calipers, micrometers, multimeters, pressure gauges, thermocouples/RTDs, torque testers).
• Familiarity with calibration management software or CMMS; computer literacy including ERP (Deacom) and Microsoft Office.
• Hands-on experience executing IQ/OQ and equipment qualification activities.
• High school diploma or GED required; associate degree or technical certificate in electronics, instrumentation, mechatronics, industrial maintenance, or related discipline preferred. ASQ CCT preferred; CQT, ISO/IEC 17025 awareness, and OSHA 10/30 are a plus.

Mindset and Impact

• You take ownership of a program — not just tasks. When something is off, you find out why and fix the root cause.
• You lead with accountability, setting clear expectations for your team and modeling the standard yourself.
• You communicate with precision: your records are complete, your reports are clear, and you can speak to your function's performance in any meeting.
• You stay current with regulatory requirements and treat audit readiness as a baseline, not a sprint.

Why Join LSO?

• Work where your precision matters: LSO products reach patients who depend on them.
• Lead a specialized team with real ownership of two mission-critical programs.
• Gain deep experience in FDA-regulated, ISO 13485-certified manufacturing.
• Collaborate across Operations, Quality, and Engineering in a high-performance CMO environment.
• Grow in a PE-backed company with dual U.S. sites and expanding capabilities.

Work Environment

• Full-time, on-site at LSO's Brea, CA facility.
• Work occurs on the manufacturing floor and in controlled and cleanroom environments requiring gowning.
• May involve work in confined or elevated spaces and the use of hand and power tools.
• Frequent use of hands and fingers to handle tools, instruments, and controls.
• Regularly lifts and/or moves up to 25 pounds; occasionally up to 50 pounds.
• Must be able to sit or stand for extended periods, walk up and down stairs repeatedly, and walk extended distances.
• PPE required appropriate to task and area; OSHA and Cal/OSHA requirements apply.

Make an Impact

Every calibrated instrument, every qualified piece of equipment, and every documented PM completed on time is a commitment to the patients who will eventually depend on what LSO builds. As Calibration and Maintenance Supervisor, you are not just keeping the lights on — you are protecting the integrity of the entire manufacturing process. If you are ready to lead a team that takes that responsibility seriously, we want to hear from you.
