Job Description

The Manufacturing Engineer (Assembly & Testing) defines, documents, and executes the assembly and testing requirements for high-precision Jigs & Fixtures used in Electronic Gadget Manufacturing. This role bridges engineering design and execution by converting drawings into assembly process sheets, check sheets, and cross-disciplinary verification protocols across mechanical, electronic, PLC, and wiring domains. Additionally, this role takes full ownership of end-to-end testing requirements both at the Factory (FAT) and at Regional Customer Sites (Chennai, Bangalore, Hosur) during final commissioning and line integration.

CORE RESPONSIBILITIES

1. Assembly Documentation & Cross-Linkage Verification

• Process & Check Sheets:Develop Assembly Process Sheets (APS) and check sheets detailing tolerances, torque values, and assembly sequences.
• Cross-Disciplinary Audit:Rigorously verify cross-linkages between mechanical structures, electronic sensors, PLC hardware, and wiring schemes prior to testing.

2. Factory Acceptance Testing (FAT) @ Toolroom

• Factory Dry Runs:Execute complete factory-level testing requirements, including dry runs of mechanical movements, pneumatic stroke limits, and basic PLC sequences.
• Pre-Shipment Validation:Validate sensor repeatability, signal integrity, ESD grounding, and safety interlocks against drawing specs before packing for dispatch.
• Site Acceptance Testing (SAT):Lead on-site testing protocols at customer manufacturing facilities in Chennai, Bangalore, or Hosur under live production conditions.
• Line Side Troubleshooting:Perform rapid debugging of mechanical alignment, wiring drops, or sensor logic errors to achieve successful First Article Inspection (FAI) and zero downtime.

TECHNICAL REQUIREMENTS

1. Education & Regional Mobility

• Qualification & Experience:B.E. / B.Tech (3-6 yrs) or Diploma (7-10 yrs) in Mechanical, Production, or Mechatronics Engineering.
• Regional Deployment:Willingness to travel to customer plants across Chennai, Bangalore, and Hosur for site testing, commissioning, and issue resolution.

2. Specialized Testing Skills

• Testing & Schematic Literacy:Proficiency in reading GD&T drawings, 3D CAD, pneumatic circuits, electrical/PLC wiring diagrams, and executing test protocols.

Key Performance Indicator (KPI)

1. FAT First-Time Pass Rate

100% clearance of Factory Acceptance Testing protocols prior to shipment.

2. SAT & FAI Clearance

100% successful site testing and approval during customer FAI at regional sites.

3. Cross-Linkage Accuracy

Zero wiring, mechanical, or logic mismatches identified during factory or site testing.

4. Process & Test Sheet Compliance

100% completion and archiving of Assembly and Testing Check Sheets.
