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 accordance with ASME RTP-1, ASME NM.2, and EN 13121 standards. This role requires a strong foundation in mechanical design and laminate mechanics, coupled with practical knowledge of composite fabrication methods such as filament winding and contact molding. The engineer will perform detailed stress and strain analysis, develop laminate stacking sequences, and validate designs through both analytical and test-based methods. This position also supports the preparation of Fabricator's Design Reports (FDRs), ensures compliance with ASME quality programs, and provides direct engineering support to manufacturing and inspection teams. This is a key technical position that directly impacts product reliability, regulatory compliance, and manufacturability. The successful candidate will collaborate closely with project engineers, QA/QC, and production to deliver high-integrity composite systems that meet customer and code requirements.
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, code compliance, and alignment with design intent.
• Support design qualification testing, material property development, and correlation of analytical models with experimental data.
• Collaborate with Quality Assurance, Inspection, and Manufacturing to ensure design execution and documentation meet ASME audit and customer requirements.
• Provide engineering support for composite fabrication processes such as filament winding, contact molding, secondary bonding, and post-cure.
• Participate in design reviews, code audits, and nonconformance investigations, supplying root-cause analysis and corrective-action recommendations.
• Prepare technical documentation, including design reports, deviation requests, and installation procedures for customer and regulatory submittals.
• Contribute to continuous improvement initiatives, identifying opportunities to enhance design efficiency, manufacturability, and cost-effectiveness across composite product lines.

EXPERIENCE/EDUCATION/SKILL-SET REQUIRED:
Essential:

• Bachelor's or Master's degree in Mechanical, Materials, or Composite Engineering (or closely related field).
• Minimum 2 years of design and analysis experience with composite pressure vessels, tanks, or piping systems.
• Fluent in English with exceptional technical writing and presentation skills.
• Willingness to travel internationally as required.

Desirable:

• Minimum of 5 years of design and analysis experience with composite pressure vessels, tanks, or piping systems.
• Code Expertise: Proven working knowledge of ASME RTP-1, ASME NM.2, EN 13121, BS 4994, AWWA M45, and API 15LR/15HR design standards.
• Manufacturing Knowledge: Practical understanding of filament winding, contact molding, secondary bonding, and post-cure processes.
