Lead Engineer, Field Service
Ho Chi Minh City, Vietnam
Posted on Nov 3, 2026
The Impact You'll Make
The Field Service Engineer is the technical field-evidence and authorized service owner for assigned customer issues. The role prepares for and conducts onsite or remote technical investigations, documents installation and operating conditions, collects reliable evidence, performs authorized diagnostics or service actions, and delivers objective field reports to support claim handling, root-cause analysis, corrective action, and customer recovery.
The FSE represents the company professionally at customer locations and must communicate verified observations clearly while avoiding unsupported conclusions or commitments. The role does not own the formal claim record, final customer claim closure, site root-cause approval, site corrective-action implementation, global QMS policy, or commercial settlement.
What You’ll Be Doing
- Pre-visit Preparation: Review the claim, product configuration, drawings, specifications, operating history, previous service activity, known issues, required tools, safety requirements, and investigation objectives before travel or remote support.
- Customer Coordination: Coordinate access, timing, site requirements, contacts, equipment availability, operating conditions, and safety expectations through the FSE Manager, CCH case owner, Sales, or designated customer contact.
- Safety and Risk Assessment: Complete required pre-task and onsite risk assessments; follow customer and company safety requirements; stop work and escalate when conditions are unsafe or outside authorization.
- Onsite Investigation: Inspect the product, installation, interfaces, environment, controls, operating conditions, maintenance condition, and failure evidence using approved methods.
- Technical Diagnostics: Perform measurements, functional checks, data-log review, controlled tests, troubleshooting, and fault isolation within approved technical and safety limits.
- Evidence Collection: Capture clear photographs, video, measurements, serial and lot data, configuration information, software or parameter versions, environmental information, witness statements, and other relevant facts.
- Sample Management: Identify, label, protect, document, and coordinate shipment of failed parts, fluids, debris, components, or other samples while preserving traceability and chain of custody.
- Authorized Service: Perform or support approved adjustment, repair, replacement, commissioning, or temporary restoration activities; document the exact work performed and resulting condition.
- Customer Technical Communication: Explain observed facts, next steps, limitations, and required follow-up clearly and professionally; avoid assigning blame or presenting unverified root cause as fact.
- Field Reporting: Submit timely, factual, and complete field reports that distinguish observations, measurements, customer statements, analysis, hypotheses, actions performed, and open questions.
- Technical Support to Investigation: Support Site Quality and Engineering with follow-up questions, test planning, evidence interpretation, reproduction attempts, and verification of corrective actions in the field.
- Escalation: Immediately escalate potential safety concerns, widespread failure, unauthorized changes, severe application mismatch, recurring defects, product misuse that may create risk, or conditions likely to affect additional customers.
- Tools and Calibration: Maintain assigned tools, diagnostic equipment, software, calibration status, documentation, and readiness for deployment.
- Knowledge Sharing: Share field lessons, recurring observations, serviceability concerns, and effective diagnostic practices with FSE peers and relevant quality and engineering teams.
- Expense and Travel Compliance: Manage travel, time reporting, expenses, customer-site conduct, confidentiality, and company property in accordance with policy.
