If contract, in initial duration will be 12 months.\nThere has never been a more exciting time to join NUVIA UK. As a result of significant growth and major contract awards, including the STEP fusion programme and major frameworks supporting the UK's defence and nuclear infrastructure, we are expanding our capability and delivering some of the UK's most innovative and strategically important programmes. Operating across the nuclear, defence and energy sectors, our work supports critical national infrastructure, strengthens energy security and contributes to the UK's long-term resilience.\nPurpose\nTo provide an embedded Lead Geotechnical Engineer within the STEP Design Authority (DA) to define, integrate and assure the geotechnical design basis for the STEP Prototype Plant (SPP).\nThe role exists to guarantee foundation performance, ground stability and soil-structure interaction for safety-classified and non-safety-classified structures under normal, seismic, extreme and faulted conditions, ensuring geotechnical risks are demonstrably ALARP and suitably justified for the DCO, nuclear safety case and construction phases.\nRequired Outcomes\nA STEP site geotechnical design basis that is coherent, traceable and defensible for DCO and nuclear safety case purposes.\nClear demonstration that ground-related hazards (e.g. liquefaction, settlement, slope failure) are identified, mitigated and managed across the plant lifecycle.\nAssured foundation and earthworks solutions for heavy, safety-significant fusion structures.\nIntegration of geotechnical data and assumptions into STEP’s digital twin and information management environment, supporting configuration control and long-term traceability.\nGeotechnical evidence packs suitable for:\nDCO submission and Examination\nSafety Case (PCSR / PSR inputs)\nIndependent assurance and regulatory scrutiny\nKey Responsibilities\nDefine and maintain the geotechnical design basis and parameters, aligned with STEP safety functional requirements and classification.\nAssess and manage liquefaction, total and differential settlement, bearing capacity and slope stability risks for the SPP site.\nDevelop and assure ground improvement strategies appropriate for large, heavily-loaded, vibration- and seismic-sensitive nuclear structures.\nProvide authoritative input to:\nSeismic hazard response and load transfer\nBlast and extreme event assessments\nSoil-structure interaction modelling\nIntegrate geotechnical data, models and assumptions into the STEP digital twin, supporting lifecycle change control and traceability.\nSupport safety case authors by providing defensible geotechnical arguments, limits and claims.\nInterface with civil, structural, seismic, safety, CDM and construction teams to ensure design integration and buildability.\nIdentify geotechnical risks to programme, safety or cost and support optioneering to reduce uncertainty at early design stages.\nEmployee Staff Benefits:\n8.5% Pension Contribution & Life Assurance\nPrivate Medical Scheme*\nEmployee Share Scheme\nSalary Sacrifice Schemes: Electrical Vehicles, Technology and Cycle to Work\n18 Weeks Full Maternity Pay* (+21w SMP)\n25 days holiday (increasing to 28 days after 5 years’ service, 31 days after 10 years’ service)\nOption to buy, sell and carry over up to 5 days annual leave per year\nIn partnership with trade unions\nPersonal Development & Further Education Support\nLong Service & Recognition Awards\nFree Employee Assistance Programme\n*After 1 year of service.","description_format":"text","description_chars":3854,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual
