Generalmatter Mechanical Design Engineer at General Matter transforms conceptual process designs into detailed mechanical systems for a nuclear enrichment facility. The role includes component selection, structural analysis, and collaboration to ensure safe and reliable process architectures.

Responsibilities

Translate P&IDs and process architecture outputs into detailed mechanical designs for piping and equipment systems.
Perform component sizing and selection (pipes, valves, fittings, supports) based on process conditions (flow, temperature, pressure).
Collaborate on routing plans and layouts for piping systems, ensuring efficient and maintainable configurations.
Conduct structural and flow analysis to validate mechanical integrity and performance under operating conditions.
Specify materials, thicknesses, and support methods to meet safety, regulatory, and operational requirements.
Prepare detailed engineering drawings, BOMs, and procurement specifications for mechanical systems.
Select components that meet technical requirements while considering availability and lead times, ensuring designs can be executed on schedule without compromising quality or safety.
Collaborate with process engineers, structural engineers, and procurement teams to ensure seamless integration of designs.
Participate in design reviews and risk assessments, providing technical justification for design decisions.
Support installation planning and provide technical oversight during construction phases as needed.
