Technical authority for injection molded components and multi-material plastic assemblies used in automotive fluid systems, including capless fuel filler systems and quick connectors for fuel, coolant and other fluid-carrying applications. This is a specialist role focused on design depth and advanced development rather than program ownership: the incumbent provides expert design, materials and validation direction across programs, and develops new plastic and sealing technologies ahead of customer application.

• Acts as the technical authority in the area of specialization for injection molded components and multi-material plastic assemblies (elastomeric seals, metal clips, springs and retention features) across the fluid systems product portfolio.
• Designs and develops complex injection molded components and assemblies for capless fuel systems, quick connectors, fuel, coolant and other automotive fluid applications.
• Performs geometric dimensioning and tolerancing (GD&T) stack-up analysis per ASME Y14.5 for plastic components and multi-material assemblies, including sealing interfaces, retention features and the effects of thermal and dimensional variation.
• Evaluates and selects engineering thermoplastics and elastomers — including polyamides (nylon), PPA and other high-performance resins, and EPDM, FKM and TPV sealing materials — based on mechanical requirements, sealing performance, chemical resistance, permeation and environmental exposure, with emphasis on fuel and fluid-carrying applications.
• Interprets mold fill simulation results to predict weld lines, air traps, shrink and warp, and to determine gate locations; provides direction to tooling and molding partners.
• Works as part of the design and development team by providing design and analysis direction, and by reviewing the designs of others.
• Provides technical mentoring for engineers, designers, co-ops and interns.
• Expected to use a broader knowledge base to take on more complicated assignments.

• Leads advanced development of new plastic components, sealing systems and joining or retention concepts ahead of customer program application.
• Evaluates alternate materials and emerging supplier technologies; defines and executes feasibility studies and bench evaluations and supports material and technology approvals with OEM customers.
• Develops and maintains design standards, design guidelines and lessons learned for injection molded and plastic fluid components.
• Identifies and supports protection of intellectual property resulting from development activity, including invention disclosures.

• Acts as technical consultant to program teams, identifying design solutions that meet the required engineering,…
