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

Senior Design Integration Engineer 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. Primary Roles & Responsibilities Design Integration & Interface Ownership Own and manage design interfaces across: Facility layout Piping systems Structural systems Vendor equipment and skids Site utilities and infrastructure Ensure consistency and alignment across drawings, models, and vendor inputs Serve as the technical point of integration between disciplines Assumptions & Design Basis Management Validate, document, and track design assumptions, including: Equipment loads and envelopes Clearances and maintenance access Elevations and interfaces Construction sequencing constraints Identify assumption changes early and assess downstream impacts Execution-Focused Design Development Translate evolving project inputs into coordinated, buildable designs Ensure layouts reflect real-world installation, access, and sequencing needs Challenge incomplete, conflicting, or high-risk inputs before they reach construction Constructability & RFI Prevention Lead constructability thinking across disciplines Identify and resolve: Installation conflicts Access and maintenance issues Temporary support and sequencing concerns Proactively reduce RFIs, rework, and field-driven design changes Piping & Structural Support Provide hands-on support for: Piping layout, routing, and support concepts Structural framing, foundations, platforms, and supports Perform basic piping and structural calculations as required to validate layouts and concepts Coordinate piping and structural elements to ensure compatibility and buildability Clash Resolution & Change Management Lead Navisworks model coordination and clash resolution Resolve conflicts across disciplines rather than simply reporting them Manage and communicate change impacts to drawings, models, schedule, and execution sequence Leadership & Coordination Act as an execution-focused extension of Valar project leadership Support coordination meetings and design reviews with practical, build-oriented input Provide clear recommendations and decision support to leadership
