Job summary

ST Engineering MRAS is seeking a Principle Engineer – Polymer Materials to act as the senior technical authority for polymer science, composite materials, and advanced resin systems used across MRAS’s programs.

The role leads synthesis, formulation, characterization, evaluation, and qualification of polymer-based materials for both new technology development and production maturation, partnering with engineering, R&D, quality, and suppliers to ensure performance and regulatory compliance.

Qualifications

• Ph.D. in Chemistry with a specialization in polymer materials, ceramic–polymer nanocomposites, thermosets, and advanced materials systems.
• More than 8 years of experience in polymer synthesis, advanced composites, thermoset chemistry, nanocomposites, and multifunctional material development for high‑performance applications.
• Expertise in polymer synthesis, functionalization, and structure–property relationships, including benzoxazine, epoxy, polyurethane, polyamide, PVC, elastomeric systems, and ceramic‑reinforced composites.
• Strong hands‑on experience with polymer and composite characterization, including FTIR, NMR, DSC, TGA, DMA, SEM, rheometry (ARES G2), mechanical testing, and cure kinetics analysis.
• Proven record of designing, developing, and optimizing thermosets, polymer–ceramic nanocomposites, and multifunctional composite materials for aerospace and high‑performance applications.
• Experience leading end‑to‑end R&D, including material synthesis, purification, formulation, scaling, processing, and laboratory‑to‑pilot transition activities.

Responsibilities

• Lead development of new polymer resin systems, adhesives, toughened matrix systems, and composite formulations for advanced structures.
• Direct synthesis, chemical modification, and formulation of polymer systems to achieve desired structural, processing, and durability characteristics.
• Develop new or improved composite lay‑up, cure, bonding, and consolidation processes linked to material chemistry.
• Act as the technical focal point for all polymer material selection, performance definition, and risk assessment.
