Core Responsibilities

Primary Functions

Perform on-site installation, setup, configuration, and commissioning of electromechanical systems, instrumentation, or production equipment, ensuring installations meet manufacturer specifications, customer requirements, and local codes.
Troubleshoot and repair electrical, mechanical, pneumatic, and electronic faults using multimeters, oscilloscopes, calibration tools, and specialized diagnostic equipment to restore equipment to productive operation.
Execute preventive maintenance programs and scheduled inspections, including lubrication, alignment, filter changes, sensor recalibration, and firmware updates to extend equipment life and reduce unplanned downtime.
Conduct root cause analysis for repeat failures, develop corrective action plans, and implement permanent fixes in collaboration with engineering and product teams.
Provide on-site and remote technical support via phone, video, and remote-access tools to rapidly diagnose issues, escalate when necessary, and minimize mean time to repair (MTTR).
Install and configure PLCs, HMIs, embedded controllers, industrial networking equipment (Ethernet/IP, Modbus, ProfiNet), and IoT gateways, including software loading and parameterization.
Perform calibration, verification, and validation of measurement instruments and control systems, documenting results and maintaining traceability in accordance with quality and regulatory standards.
Maintain accurate, timely service records and detailed field reports in the CRM or service management system (e.g., ServiceNow, Salesforce Field Service, Microsoft Dynamics) including time on site, parts used, root causes, and customer sign-off.
Manage spare parts inventory at customer sites and in field vehicles; forecast parts usage, place orders, and work with logistics to ensure critical parts availability to meet SLAs.
Deliver customer training and operational handovers for end users and maintenance teams, including safety briefings, operation best practices, and troubleshooting tips to reduce service calls.
Support warranty and RMA processes by documenting failures, coordinating parts returns, and liaising with warranty administration to ensure timely resolution and cost recovery.
Adhere to and promote company and customer safety policies, confined space procedures, lockout/tagout protocols, and environmental regulations during all field activities.
Collaborate with product development and engineering teams to relay field feedback, identify product improvements, and support design-for-serviceability initiatives.
Execute service contracts and work to defined SLAs, prioritizing service dispatches, and communicating professionally with dispatchers and customers about expected arrival windows and resolution timelines.
Use mobile service apps and tablet-based workflows to capture photos, measurements, and digital signatures; ensure compliance with digital documentation standards.
Provide escalation support for complex technical issues and participate in on-call rotations for emergency and after-hours support when required.
Perform software upgrades, patch management, and configuration backups for embedded systems and industrial control systems to maintain security and functionality.
Support commissioning acceptance tests and customer acceptance criteria, including FAT/SAT preparation, execution, and formal sign-off documentation.
Participate in continuous improvement initiatives, including root cause trend analysis, spares rationalization, and updates to service playbooks and technical procedures.
Maintain professional relationships with customers by delivering status updates, explaining technical issues in lay terms, and ensuring a high level of customer satisfaction and repeat business.
Coordinate with third-party contractors, vendors, and subcontractors during complex installations or repairs to ensure scope, safety, and quality are maintained.
Track and report key field service KPIs such as first-time fix rate, response times, uptime, and customer satisfaction scores to service leadership.
Prepare and deliver field-based acceptance and project closeout documentation, including corrective action logs, punch lists, and final as-built documentation.
Conduct risk assessments and implement mitigation measures before any field activity that could impact safety, quality, or customer operations.
Implement remote-monitoring setups or telemetry solutions when applicable and train customers on alarm management and remote diagnostics features.

Secondary Functions

Support ad-hoc data requests and exploratory analysis for service trends, failure modes, and parts consumption to help optimize field inventory and preventive maintenance plans.
Contribute to the organization's field service technology roadmap by recommending tools for remote diagnostics, augmented reality (AR) assistance, and mobile workflows.
Collaborate with business units (sales, engineering, quality) to translate customer feedback and service analytics into product improvements and service offerings.
Participate actively in sprint planning and agile ceremonies within cross-functional teams focused on service tool development, knowledge-base content, and technical documentation.
