Job summary

NUVIA seeks a Lead Geotechnical Engineer to embed within the STEP Design Authority, directing geotechnical design basis for the Prototype Plant. The role ensures foundation performance, ground stability and soil–structure interaction for safety-classified structures under diverse conditions.

You will integrate data into STEP’s digital twin, support safety cases and collaborate with civil, seismic, safety and construction teams. Hybrid work arrangement with site presence preferred.

Qualifications

• Requires geotechnical design basis expertise.
• Ability to identify and mitigate ground-related hazards across lifecycle.
• Experience integrating geotechnical data into digital twin environments.
• Demonstrated ability to support safety cases and regulatory scrutiny.

Responsibilities

• Define and maintain the geotechnical design basis and parameters, aligned with STEP safety functional requirements and classification.
• Assess and manage liquefaction, settlement, bearing capacity and slope stability risks for the SPP site.
• Develop and assure ground improvement strategies for large, seismic‑sensitive nuclear structures.
• Seismic hazard response and load transfer.
• Blast and extreme event assessments.
• Integrate geotechnical data, models and assumptions into the STEP digital twin, supporting lifecycle change control and traceability.
