Job Summary

We are looking for an experienced QA/QC professional with hands‑on experience in rubber gasket manufacturing, testing, quality assurance, and product certification.

The ideal candidate should have a strong background in rubber moulded products, particularly pipe gaskets for GRP/GRP composite pipes and ductile iron (DI) pipes, flange gaskets, O-rings, Elastomeric bearings, manufactured using Natural, Neoprene, EPDM, FKM (Viton), HNBR, and other rubber compounds.

The candidate will be responsible for establishing and maintaining quality systems, conducting in-house and third‑party product testing, managing customer and certification audits, and obtaining and renewing product approvals such as WRAS, NSF and BIS, as applicable to our products and target markets.

Candidates currently working in rubber gasket, rubber moulding, elastomeric sealing, or polymer product manufacturing companies will be strongly preferred.

1. Quality Control & Laboratory Testing

• Conduct incoming raw material, in-process, and final product inspection and testing.
• Test rubber compounds and finished rubber gaskets for hardness (Shore A/IRHD), tensile strength, elongation at break, compression set, ageing resistance, and other relevant physical properties.
• Evaluate rubber compounds and products for suitability in Natural Neoprene, EPDM, FKM, HNBR and other elastomer applications.
• Ensure Rubber Material Testing accuracy, profile conformity, tolerances, sealing performance, and consistency of pipe gaskets, flange gaskets and O-rings.
• Develop and implement inspection and testing plans, sampling procedures, acceptance criteria, and product‑specific quality standards.
• Maintain laboratory equipment, calibration records, test reports, inspection reports and certificates of analysis.
• Coordinate with accredited external laboratories for specialised testing when required.

2. Product Approvals & Certifications

• Independently coordinate and drive product approval and certification processes, including WRAS, ISO 4633, EN 681, NSF and BIS, wherever applicable.

• Prepare technical dossiers, product specifications, drawings, material declarations, test reports and other documents required for certification.
• Liaise with certification bodies, testing laboratories and regulatory agencies for product evaluation, audits, testing and approval.
• Coordinate product sample submission, laboratory testing, factory inspections, corrective actions and certification renewals.
• Track approval timelines, identify compliance gaps, and ensure timely closure of certification requirements.
• Maintain a certification register covering validity, renewal dates, applicable products and compliance status.

3. Rubber Standards & Technical Compliance

• Interpret and implement relevant IS 5382, EN, ISO 4633, ASTM and other applicable standards for rubber gaskets and elastomeric sealing products.
• Experience with standards such as EN 681-1, IS 5382, and other relevant pipe gasket or elastomer specifications will be an advantage.
• Understand material and product requirements for potable‑water applications, including applicable material safety and migration requirements.
• Ensure product‑specific compliance with customer specifications and the relevant requirements of the target market.

4. Quality Management Systems & Audits

• Implement and maintain an effective Quality Management System, preferably ISO 9001.
• Prepare for and coordinate customer audits, certification audits, and internal audits.
• Manage non‑conformities, root cause analysis, corrective and preventive actions (CAPA), and customer complaints.
• Prepare and maintain SOPs, quality manuals, inspection formats, control plans and standard testing procedures.
• Analyse quality data, identify recurring defects, and drive continuous improvement in product quality and process consistency.

5. Manufacturing & Cross‑Functional Coordination

• Work closely with production, moulding, compounding, purchase and dispatch teams to prevent quality issues.
• Monitor critical manufacturing parameters and ensure consistent product quality across batches.
• Approve or recommend disposition of non‑conforming materials and finished products according to established procedures.
• Support new product development, rubber compound qualification, process validation and customer‑specific approvals.
• Train production and inspection personnel on quality standards, testing procedures and documentation.

Mandatory Requirements

• Relevant experience in QA/QC within a rubber gasket, rubber moulding, elastomeric sealing or similar polymer manufacturing environment.
• Practical knowledge of rubber testing methods and interpretation of test results.
• Experience handling quality documentation, inspection procedures and customer quality requirements.
• Demonstrated ability to coordinate with external laboratories and certification agencies.
• Strong analytical, documentation, communication and problem‑solving skills.

Preferred Experience

• Prior experience in pipe gasket manufacturing for GRP/GRP composite or ductile iron pipes.
• Experience with flange gaskets, O-rings and rubber products made from EPDM, FKM and HNBR.
• Successfully obtained or renewed product certifications such as WRAS, NSF or BIS for relevant products.
• Knowledge of EN 681-1, IS 5382, ISO 9001 and applicable ASTM/ISO/IS standards.
