SI Solutions, LLC Tech Stack

Engineering services for nuclear, power, and critical infrastructure

Engineering Services Charlotte, NC 201–500 employees Founded 2023 Privately Held

SI Solutions is a 201–500-person engineering services firm founded in 2023, heavily staffed with senior engineers (21 of 34 active hires). The tech stack reveals deep domain specialization: FEA tools (ANSYS, ABAQUS, LS-DYNA), CAD/BIM (AutoCAD, Revit, SolidWorks), and simulation software (MATLAB, STAR-CCM+) dominate, with project work spanning nuclear life extension, thermal-fatigue analysis, and pressure-vessel design. No adopting or replacing signals suggest a stable toolset tailored to regulatory-heavy, long-cycle infrastructure engineering.
