Ideal candidates bring strong analytical skills, experience with seismic modeling tools, and the ability to communicate technical findings effectively.

Responsibilities

• Perform geotechnical seismic hazards analyses, 1D and 2D site‑response, and soil‑structure‑interaction evaluations for projects utilizing FLAC, PLAXIS, and other geotechnical modeling software for analysis and design.
• Coordinate with cross‑functional teams to validate structural assumptions and address emergent issues.
• Develop and execute geotechnical numerical models with a focus on seismic analyses and soil‑structure interaction including but not limited to:
  • Collect and analyze geotechnical data (borings, CPTs, lab data, etc.),
  • Perform model calibration including element‑and‑system‑level evaluations,
  • Develop model space and boundary conditions,
  • Perform model response and diagnostic evaluations,
  • Post‑processing and presentation of model results, and
  • Translation of model response to actionable geotechnical design recommendations.
• Perform geotechnical engineering analyses, studies, and calculations, and prepare reports.
• Review technical reports and calculations prepared by entry‑level engineers.
• Support business development and marketing activities, including preparation of cost proposals and presentations to existing and prospective clients.
• Perform field explorations, collection of samples, geologic reconnaissance, and mapping.
