Responsibilities

Formulate, optimize, and qualify sealants, structural and non-structural adhesives, elastomers, gaskets, and rubber compounds to meet application-specific performance requirements including adhesion, flexibility, environmental resistance, outgassing, and curing behavior.
Define material specifications, acceptance criteria, engineering standards, and laboratory test methods for sealants, adhesives, rubber (SAR) materials, and assemblies.
Plan, perform, and interpret laboratory testing including: Lap shear and peel adhesion testing, Cure kinetics evaluation, Rheology and viscosity analysis, Shore A/D hardness testing, Tensile strength and elongation testing, Compression set evaluation, Fatigue and cyclic durability testing, Environmental exposure testing (temperature, humidity, UV), Outgassing analysis, Chemical resistance testing.
Develop, validate, and maintain manufacturing application processes including dispensing, priming, curing, bonding, and pot life controls.
Lead root cause investigations of adhesive, sealant, elastomer, and rubber failures; implement and monitor corrective and preventive actions (CAPA).
Support manufacturing scale-up, production transfer, and continuous improvement by developing work instructions, process control plans, manufacturing trials, and operator training.
Qualify and audit suppliers of raw materials, adhesives, sealants, and elastomeric components; review supplier certifications, test reports, and certificates of conformance.
Ensure compliance with ASTM, aerospace outgassing requirements, D6 standards, and other applicable industry and regulatory specifications.
Maintain laboratory equipment including rheometers, curing ovens, adhesion testers, and environmental chambers while managing laboratory inventory and consumables.
Prepare technical reports, qualification packages, engineering documentation, and test plans; present findings and recommendations to Design Engineering, Manufacturing, Quality, Production, and Supply Chain teams.
