System Engineer - Heat Transfer Equipment

About this role

Responsibilities

• You will take ownership of the steam generator - one of the most critical components in our SEALER reactor, sitting at the interface between the lead-cooled primary circuit and the power conversion system. You are the system-responsible engineer: defining what it must do, how it should be designed, and who builds it.
• The role spans the full engineering lifecycle — from writing requirements and leading trade-off studies, through detailed design, manufacturing coordination, and qualification. You will combine sharp mechanical engineering judgment with the ability to align people, suppliers, and analyses toward a common technical goal.
• What you'll get to do
• Your work spans three interconnected areas.
• On the requirements and design basis side, you will define the steam generator's functional and design requirements, develop and maintain the design basis documentation, and lead trade-off studies on configuration, materials, and manufacturing approaches.
• On the mechanical design side, you will drive decisions on component architecture, assembly sequences, weldability, inspectability, and manufacturability — making sure the design is practical to fabricate, transport, install, test, and maintain.
• On the thermal-hydraulic and structural side, you will not run complex simulations yourself, but you will be the one asking the right questions: defining calculation scopes, providing inputs to analysts, and critically reviewing results. You should be comfortable performing hand calculations to sanity-check outputs and steer design iterations.
• On the coordination side, you will define the scope and technical content of s
