Principal Structural Engineer - Dynamic Design Analysis

About the role

Zachry Engineering Corporation is seeking a Subject Matter Expert (SME) who specializes in the intersection of high-level structural integrity and complex vibration theory to lead the design of massive machine foundations for combustion turbines and heavy industrial assets. This position requires in-office work from our Houston, Texas location.

Responsibilities

• Act as the Subject Matter Expert (SME) for dynamic machine-foundation-soil interaction (SSI) for combustion turbines and high-speed rotating equipment.
• Execute and oversee complex FEA to simulate thermal loads, seismic events, and harmonic vibrations, ensuring resonance separation and structural longevity.
• Drive the evolution of design standards for massive reinforced concrete structures, balancing material efficiency with extreme performance requirements.
• Lead multidisciplinary teams through the full project lifecycle—from initial geotechnical interpretation to final site construction and vibration troubleshooting.
• Conduct rigorous peer reviews and forensic engineering assessments for existing facilities to address settlement or vibration-related issues.
• Provide technical guidance throughout the structural design and engineering process, often serving as the senior reviewer of calculations and structural models.
• Prepare and deliver training for junior engineering personnel on discipline-specific technical expertise.
• Prepare data and visualizations such as tables, charts, reports, sketches, calculations, cross-sections, and 2D/3D illustrations for interpreting or presenting complex data, findings, or analyses.
• Consider construction costs, government regulations, potential environmental hazards, and other factors during planning stages and risk analysis.
• Independently evaluate, select, and apply standard engineering techniques, procedures, and criteria, making minor adaptations and modifications as needed.
• Travel to job sites to participate in walkdowns and provide construction or commissioning support.
• Coordinate with other disciplines, departments, and companies to ensure seamless technical compatibility and completion of engineering tasks safely, on-time, within budget, and meeting all quality requirements.

Requirements

• Bachelor’s Degree in Civil/Structural Engineering with a focus in Dynamic Analysis.
• 15+ years of Structural Engineering experience in the Power and Industrial industry.
• Professional registration as a Professional Engineer (P.E.) (required).
• Professional registration as a Structural Engineer (S.E.) (preferred).
• Knowledge of AutoCAD, STAADPro, RISA, Enercalc, or similar analysis software.
• Familiarity with 3D design and viewing software such as Navisworks.
• Experience with large power generation and industrial projects.
• Knowledge and understanding of engineering, construction, and project management.
• Deep understanding of ACI 351.3R (Foundations for Dynamic Equipment) and rotating machinery dynamics.
• Excellent communication and presentation skills.
• Strong Microsoft Office software skills.
• Must possess authorization to work in the United States for any employer without the need for sponsorship now or in the future.
