Products are sold through wholesale distribution across the United States and Canada for use on properties with onsite wastewater treatment systems.

The Senior Composite Design Engineer will lead the development and design of FRP (fiber‑reinforced polymer) composite products for infrastructure applications. This engineer leader will utilize their strong background in composite materials and processes, particularly in closed molding methods such as RTM (Resin Transfer Molding) and vacuum infusion, structural engineering capabilities and knowledge of infrastructure and related codes to develop infrastructure products like tanks, buildings, and structural covers.

• Continuously maintains Orenco management's safety, cultural, and professional standards.
• Promotes, encourages, and reinforces a positive safety culture, safe practices, and a safe work environment for all employees.

• Lead the design and development of FRP composite products for infrastructure applications.
• Collaborate with the Composite Sales Manager to develop tailored design solutions for customer projects.
• Collaborate with the Composite Sales Manager to identify new product development opportunities and cultivate strategic OEM (Original Equipment Manufacturing) relationships that drive innovation and long‑term business growth.
• Drive value engineering initiatives to enhance design efficiency and reduce cost.
• Oversee and optimize manufacturing processes, especially closed molding techniques (RTM, vacuum infusion).
• Collaborate on material selection, including resins, reinforcements, core materials, adhesives, and coatings.
• Interpret and apply relevant codes and standards (e.g., IBC, AASHTO, ASCE, ASTM) to ensure code compliance in structural designs.
• Perform structural analysis and guide product testing and validation.
• Work closely with the retiring engineer through a transition period to absorb institutional knowledge, processes, and legacy designs.
• Support cross‑functional teams including production, QA/QC, sales, and product and project management.
• Interface with customers, certification agencies, and third‑party engineers as needed.
• Represent the company at key composite industry events (e.g., trade shows, technical conferences) to stay current with industry trends and strengthen professional networks.

Regular, consistent, and predictable attendance is required.

Performs other duties as assigned.

Bachelor's degree in Mechanical Engineering, Civil Engineering, Structural Engineering, Materials Science, or related field.

• Minimum 5 years' experience in composite product design (10+ years preferred).
• Expertise in closed‑mold composite processes.
• Strong structural engineering capabilities and working knowledge of composite materials – resins, fibers, cores, adhesives, etc.
• Familiarity with infrastructure products and relevant codes and standards for infrastructure (IBC, ACI, AISC, ASCE, AASHTO, ASTM).
• Proficiency in 3D modeling CAD (Computer‑aided design) (e.g., Solid Works, Inventor,…
