Job description

Position Overview

We are seeking a highly analytical and process-driven Senior Rubber Technologist & QA/QC Lead specializing for Deesawala Rubber Industries, which specializes in in high-performance sealing systems, gaskets, and larger dia O-rings, Rubber Pads for Bridges, rail pads, etc This dual-focused role bridges the gap between raw polymer chemistry and rigorous factory floor quality control. The ideal candidate will have extensive hands‑on experience formulating, testing, and certifying compounds across a diverse material matrix (EPDM, Nitrile/NBR, Neoprene, FKM, Viton, and FFKM perfluoroelastomers). Beyond material science, this professional will establish, monitor, and enforce end-to‑end Quality Assurance (QA) protocols and Quality Control (QC) product testing regimes, ensuring full operational alignment with strict international regulatory approvals.

Key Responsibilities

1. Compound Design, Deformulation & Process Engineering

• Advanced Sealing Formulation: Formulate and optimize custom rubber recipes for static and dynamic gaskets, adjusting mechanical performance for aggressive chemical exposures, extreme steam/water pressures, and high thermal limits.
• Multi-Elastomer Expertise: Lead technical compounding across EPDM, Neoprene, Nitrile (NBR), FKM/Viton, and high-value FFKM peroxide/bisphenol curing systems.
• Material Reverse Engineering: Conduct full structural deformulation and reverse-engineering of competitor or legacy components using analytical laboratory data.

2. QA/QC Systems & Product Testing Management

• End-to-End QA Architecture: Define, build, and enforce rigorous standard operating procedures (SOPs), Inspection Test Plans (ITPs), and quality control guidelines from incoming raw chemical inspection to final finished gasket dispatch.
• Routine & Structural QC Testing: Direct physical, mechanical, and environmental property testing, including Tensile Strength, Elongation, Hardness (Shore A/IRHD), Compression Set, Rheology (MDR/ODR), Stress Relaxation, Liquid Immersion Aging, and Ozone Degradation.
• Non-Conformance & Failure Analysis: Lead root-cause failure analysis on both internal manufacturing rejects and field failures (e.g., explosive decompression, chemical swelling, physical extrusion, or premature sealing degradation). Implement swift, permanent corrective and preventive actions (CAPA).
• Supplier Quality & Audit Management: Audit external chemical vendors and masterbatch suppliers to ensure incoming material consistency, preventing compound variance before mixing begins.

3. Global Regulatory & Certification Alignment

• Potable Water Approvals (WRAS & NSF): Formulate and validate rubber compounds to strictly comply with international potable water and public health certifications.
• Infrastructure Piping Standards (EN 681-1 / ISO 4633): Establish product compliance framework in accordance with structural standards for infrastructure piping, water supply networks, and sewerage drainage systems.

Required Qualifications & Technical Skills

• Education: Bachelors or Masters degree in Polymer Science, Rubber Technology, Chemical Engineering, or a related material science discipline.
• Experience: 6+ years of direct industrial experience spanning both rubber compounding/manufacturing and dedicated QA/QC product testing frameworks within the seal, gasket, or automotive components sector.
• Analytical & Quality Tool Mastery: Deep working proficiency with lab testing instruments (FTIR, TGA, DSC, GC-MS, Moving Die Rheometers) combined with mastery of standard QA software, statistical process control (SPC), and gauge R&R evaluations.
• Testing Standards: Comprehensive knowledge of international testing standards including ISO, ASTM, and DIN protocols specific to elastomeric seals.
