Position: (C) Senior Design Integration Engineer (Facility / Site / Piping / Structural Execution Lead)

Description

Background check, US Citizenship, and a drug screening are requirements for this position. Travel is 25%. Pending client approved candidate.

The engineer will only need to be on site for 2-months before returning to a remote position with the understanding that the engineer may be required to return to Orangeville UT ~ once a quarter to attend meetings/ conferences/ etc.

The Senior Design Integration Engineer provides execution leadership and full design integration ownership for a complex facility and site development project. This role actively manages design interfaces, assumptions, constructability, and change impacts across facility, piping, structural, vendor, and site disciplines.

This position is focused on risk reduction and schedule protection, not just drawing production. The Senior Design Integration Engineer serves as an execution-focused extension of Valar leadership, ensuring evolving inputs are translated into coordinated, buildable designs and that downstream construction issues are identified and resolved early.

This role does not perform nuclear reactor physics or licensing work.
