The Senior Reliability Technician is responsible for improving the reliability, availability, and performance of variable frequency drive equipment across WaterBridge’s facilities and infrastructure. This role combines hands-on field diagnostics with data-driven analysis to reduce unplanned downtime, extend equipment life, and drive continuous improvement in maintenance and reliability practices. This position consolidates responsibilities of a Field Technician, VFD Technician, Analyst and Reliability Specialist into a single role.
Primary Duties and Responsibilities:
Equipment Reliability & Diagnostics
Monitor, troubleshoot, and analyze the performance of VFD equipment
Perform root cause failure analysis (RCFA) on equipment failures and recommend corrective and preventive actions.
Use condition-monitoring techniques to detect early signs of equipment degradation.
Leverage SCADA platform and available ai tools to trend and monitor VFD parameters
Conduct field inspections and walk-downs to identify reliability risks and integrity issues.
Act as a ‘special projects rover’ for ad hoc I&E/VFD initiatives
Reliability Program Support
Leverage CMMs program (work orders) to improve failure coding, close out quality, analyze WO history and validation of asset data feeding the WO.
Support and continuously improve WaterBridge’s reliability program, including predictive maintenance (PdM), preventive maintenance (PM) optimization, and reliability-centered maintenance (RCM) practice through work order scheduling and collaboration with stakeholder groups.
Participate in Management of Change (MOC) reviews for equipment modifications, upgrades, and repairs.
Technical & Field Support
Lead field support during VFD startups (PSSRs), shutdowns, turnarounds, and commissioning activities.
Partner with maintenance, operations, and engineering teams to troubleshoot equipment issues and implement solutions.
Partner with internal I&E stakeholders and vendors during install, teardowns and repairs
Support spare parts strategy and criticality assessments for rotating equipment assets.
Collaboration & Continuous Improvement
Work cross-functionally with maintenance and operations to prioritize and close out reliability improvement actions.
Mentor junior technicians on reliability best practices and diagnostic techniques.
Contribute to reliability standards, procedures, and best-practice documentation across sites.
Qualifications and Experience:
5 years of hands-on troubleshooting on low and medium-voltage drives. Oilfield or water-handling experience strongly preferred.
Expert understanding of drive fundamentals: rectifier and DC bus behavior, IGBTs, and PWM. Ability to read a fault log and tell a supply-side problem from a load-side problem.
Manufacturer specific experience preferred – Yaskawa
Understanding of Modbus and Ethernet/IP, and how drives tie into SCADA for remote monitoring and alarms.
Understanding of constant and variable torque applications
Understanding of enclosure cooling, dust ingress, cooling fan/heat sink wear.
Familiarity with reliability methodologies such as RCFA, RCM, FMEA, 5 Whys, Fishbone)
Strong analytical skills with the ability to interpret equipment and process data to identify reliability trends.
Ability to work in and travel to field environments
Strong communication skills, with the ability to translate complex technical findings into actionable and understandable recommendations for cross-functional teams.
Experience with CMMS/EAM platforms (e.g., SAP PM, Maximo) and reliability software tools preferred.
Familiarity with affinity laws is preferred.
Working Conditions/Environment:
This is a field-based role requiring regular presence at site locations, including exposure to outdoor industrial environments, noise, heights, and confined spaces as applicable. Occasional off-hours support (e.g., during commissioning or equipment failures) may be required.
Position Type:
This is a full-time position.
