Description
Job Summary

The Design Engineer – Custom Composite Structures is responsible for the design, analysis, and certification of reinforced thermoset plastic (RTP) vessels and piping systems in compliance with ASME RTP-1, ASME NM.2, and EN 13121. The role involves performing stress and strain analysis, developing laminate designs, and validating performance through analytical and test methods.

The engineer reviews and approves fabrication drawings to ensure compliance with design requirements, codes, and manufacturability, and supports the preparation of Fabricator’s Design Reports (FDRs) and ASME quality programs. This position requires strong knowledge of composite materials, laminate mechanics, and fabrication processes such as filament winding and contact molding.

Working closely cross-functional teams, the Design Engineer plays a critical role in ensuring product reliability, regulatory compliance, and effective execution of high-integrity composite systems.

Main Responsibilities
- Develop and certify design calculations, drawings,



and specifications for composite pressure vessels and piping systems per ASME RTP-1, ASME NM.2, EN 13121, and related standards (BS 4994, API 15LR/15HR).
- Prepare and maintain the Fabricator’s Design Report (FDR) in compliance with the User’s Basic Requirements Specification (UBRS) and ASME Quality Control procedures.
- Perform advanced laminate stress and strain analyses, including modeling of anisotropic material behavior and evaluation of ply-by-ply responses using Classical Laminate Theory (CLT).
- Conduct finite element analysis (FEA) to verify compliance with ASME stress and strain-limit criteria and to assess vessel and piping performance under operating and test conditions.
- Define laminate architectures, reinforcement sequences, corrosion-barrier configurations, and joint details to meet structural and chemical service requirements.
- Review and approve fabrication and layout drawings, ensuring manufacturability
