* Develop and review components, sub-assemblies, and assemblies for VCBs and related switchgear.
* Prepare GA drawings, mounting arrangements, component drawings, electrical diagrams, pneumatic diagrams, wiring layouts, and assembly drawings.
* Work on VCB interfaces including operating mechanisms, vacuum interrupters, auxiliary contacts, control coils, pneumatic components, connectors, insulators, earthing, and surge protection arrangements.
* Ensure design suitability for railway rolling stock conditions such as vibration, shock, humidity, dust, rain, temperature variation, and outdoor roof-mounted duty.
* Identify technical ambiguities and coordinate clarifications with customers, consultants, vendors, and internal teams.
* Prepare clause-wise technical compliance statements and support design improvements, indigenisation, and value engineering.
2) Testing & Validation
* Prepare test plans, test protocols, inspection checklists, and test record formats.
* Coordinate prototype, type, routine, and acceptance testing as per applicable standards and customer requirements.
* Arrange testing with approved laboratories and inspection agencies.
* Coordinate sample readiness, fixtures, test equipment, drawings, and documentation.
* Prepare test reports, deviation reports, corrective action reports, and validation summaries.
* Support failure investigation, root cause analysis, field trials, and design corrections.
3) Documentation
* Prepare and maintain design calculations, drawings, BOMs, process sheets, work instructions, inspection plans, test records, maintenance manuals, operating manuals, spare parts lists, troubleshooting instructions, and customer approval documents.
* Prepare manufacturing reference documents such as assembly instructions, torque charts, wiring schedules, inspection checkpoints, and final inspection formats.
* Ensure all documents are revision-controlled and aligned with customer-approved drawings and specifications.
* Maintain traceability of design changes, test results, customer comments, and approval status.
4) Manufacturing & Quality Support
* Provide technical support during fabrication, assembly, wiring, pneumatic fitting, and final inspection.
* Assist in preparing inspection criteria for bought-out components such as vacuum interrupters, insulators, auxiliary switches, connectors, control coils, pneumatic components, and hardware.
* Review supplier drawings, test certificates, material certificates, and inspection reports.
* Support troubleshooting of dimensional, wiring, leakage, operational, and test-related issues.
* Coordinate with vendors for component development and technical clarifications.
