The Electrical Engineer—Field Support position provides on site and remote assistance for installed elevator systems, with a strong emphasis on troubleshooting, diagnostics, and service restoration. Under the guidance of senior field engineers, this role supports fault isolation on controllers, drives, sensors, and communication networks; documents findings; implements safe, approved corrective actions; and communicates clearly with mechanics, building stakeholders, and internal engineering teams. This is a hands on, customer facing role. 

Essential Function 
Troubleshooting, Diagnostics & Repair
•    Assist with fault isolation on elevator control panels, VFDs, door operators, encoders, limit/leveling switches, safety circuits, COP/Hall call devices, and related subsystems.
•    Use diagnostic tools such as multimeters, clamp meters, oscilloscopes, and handheld programmers to verify power, signals, grounding, and noise.
•    Support parameterization and verification of VFDs and elevator controllers, including validation of I/O maps, encoder counts, direction/leveling signals, and braking logic.
•    Assist with debugging car/group communications and device networking issues (e.g., RS-485, CAN, Modbus).
Remote Support & Technical Escalation
•    Collect logs, fault codes, and configuration snapshots and provide accurate problem descriptions for senior support and engineering escalation.
•    Apply approved firmware and parameter updates and restore validated baseline configurations when required. 
Commissioning, Maintenance & Reliability
•    Execute standardized post-repair checks, including power-up, homing/leveling, door operation, ride quality basics, emergency operations, and acceptance testing as directed.
•    Record baseline performance metrics such as voltages, currents, error counters, and trip histories for future comparison.
•    Assist with periodic inspections, functional checks, and performance measurements; identify emerging issues and recommend proactive corrective actions.
•    Capture field learnings and contribute to the continuous improvement of troubleshooting guides and service bulletins. 
Documentation, Compliance & Record Management
•    Read and interpret electrical schematics, ladder logic, single-line diagrams, and wiring schedules.
•    Redline wiring diagrams, update terminal schedules, and maintain configuration records to keep service documentation current.
•    Create concise service reports detailing work performed, test data, photos/markups, and recommendations.
•    Adhere to QA procedures and maintain traceable records of replaced parts, firmware versions, and parameter settings.
•    Ensure work aligns with applicable codes, standards, company policies, and site safety requirements.
•    Follow LOTO and site safety procedures, including verification of safety chain integrity, emergency stop circuits, and door/gate interlocks before and after service work. 
Customer, Site & Cross-Functional Coordination
•    Communicate status, risks, and next steps to mechanics, supervisors, building representatives, and other stakeholders.
•    Coordinate parts, materials, and vendor support activities to minimize downtime.
•    Partner with field mechanics, project and operations managers, product engineering, and technical support teams.
•    Provide clear handoffs and post-mortem information to support reduced mean time to repair (MTTR) and improved first-time fix rates.
