Job description

Are you a hands-on Mechanical Engineer with a passion for piping design and process systems? We’re looking for a Mechanical Engineer to join a dynamic team working on cutting-edge pilot plant and process integration projects.

You’ll design piping systems to ASME B31.3 standards, create detailed drawings using SolidWorks and MS Visio, and see your work come to life—from concept through installation.

Position Summary:

This role involves designing piping systems in accordance with ASME B31.3, creating supporting detail drawings, and performing standard design calculations. The Mechanical Engineer will be responsible for process integration from design through installation, developing bills of materials (BOMs), specifying instrumentation, and maintaining updated P&IDs. The ideal candidate will have hands-on experience, a strong understanding of mechanical and electrical systems, and the ability to support pilot plant operations and design efforts. Experience in FEA and thermal simulations is highly desirable.

Key Responsibilities:

• Design and draft piping systems compliant with ASME B31.3 standards.
• Create and maintain detailed engineering drawings using SolidWorks and MS Visio.
• Develop and manage Bill of Materials (BOMs) for designed systems.
• Specify and integrate instrumentation for mechanical systems.
• Update and maintain unit Piping and Instrumentation Diagrams (P&IDs).
• Support and supervise operations within the pilot plant as needed.
• Participate in the overall process from concept through installation.
• Conduct or assist with thermal and structural Finite Element Analysis (FEA) simulations.
• Perform thermodynamic calculations and mechanical system builds as needed.
• Contribute to plant design and operational setup.

Qualifications:

• Bachelor’s degree in Mechanical Engineering or related discipline.
• No professional experience required.
• 2 years of relevant engineering experience preferred.
• Proficiency in SolidWorks and Microsoft Excel (ANSYS experience is a plus).
• Ability to manage multiple tasks, perform calculations, and contribute to physical system builds.
• Willingness to work shifts and participate in hands-on plant activities.
• Experience with demonstration-scale operations is preferred.
