R&D Engineer

Product Design \& Development

Develop and modify electronic circuits, schematics, PCB layouts, and product designs for inverter, solar, hybrid, and related power\-electronics products.

Support design of power stages, control circuits, sensing circuits, gate\-drive circuits, protection circuits, and auxiliary power supplies as applicable.

Select suitable components based on electrical ratings, reliability, availability, cost, and approved specifications.

Prepare and maintain design calculations, circuit diagrams, BOMs, technical specifications, and engineering change records.

Prototype Development \& Testing

Build or coordinate prototype assembly and conduct functional testing, performance testing, and design verification.

Test products under defined operating conditions, including input/output voltage, load variation, temperature, efficiency, charging/discharging, and backup performance as applicable.

Evaluate product operation with relevant battery types, solar PV inputs, charge controllers, and grid/generator inputs where supported by the product.

Record test observations, measurements, failures, corrective actions, and test results in approved formats.

Troubleshooting \& Failure Analysis

Investigate circuit, PCB, firmware, thermal, electrical, and field\-return failures using systematic root\-cause analysis.

Identify component failures, design weaknesses, protection gaps, and recurring issues; recommend and implement corrective/preventive actions.

Coordinate with Production, Quality, Service, and Repair teams to resolve technical issues and reduce repeat failures.

Validate corrective actions through repeat testing before recommending release.

Solar \& Inverter System Validation

Verify inverter operation and relevant solar/hybrid functions against approved product requirements.

Check applicable protection functions, such as overload, short circuit, over/under\-voltage, over\-temperature, reverse polarity, and battery\-related protections.

Support validation of MPPT/PWM charging, changeover, battery charging profiles, and system compatibility where these features are part of the product.

Ensure tests are performed using approved procedures, suitable instruments, and safe test arrangements.

PCB, BOM \& Engineering Documentation

Review PCB layouts for manufacturability, component placement, clearances, thermal considerations, and serviceability.

Prepare, review, and update BOMs, schematics, wiring diagrams, test procedures, engineering drawings, and revision\-controlled documents.

Support PCB revisions, component substitutions, and engineering change requests with proper evaluation and approval.

Maintain traceable records for prototypes, test reports, design versions, and approved product changes.

Production \& Quality Support

Provide technical support during pilot runs, new\-product introduction, production testing, and process troubleshooting.

Work with Production and Quality teams to improve yield, reduce rework, and resolve recurring defects.

Define or improve inspection and functional\-test checkpoints in coordination with Quality and Manufacturing Engineering.

Train relevant technicians and production personnel on approved technical changes and testing methods.

Compliance, Safety \& Reliability

Follow applicable electrical safety practices, ESD controls, laboratory procedures, and company quality systems.

Support verification against relevant product standards and regulatory requirements identified by the organization.

Use calibrated instruments and approved test setups; report unsafe conditions or abnormal test results promptly.

Consider derating, thermal management, component life, reliability, and serviceability during design and validation.

Cross\-Functional Coordination \& Reporting

Coordinate with Procurement, Production, Quality, Service, and suppliers for component evaluation and technical resolution.

Provide project status, testing progress, risks, and issue reports to the R\&D Manager.

Meet agreed project milestones and escalate delays, resource constraints, and critical technical risks promptly.

Protect confidential designs, firmware, technical data, and intellectual property.
