Civil and Environmental Engineer

Position Description

Oklo is developing advanced fission power plants to deliver clean, reliable, and affordable energy at scale. As we expand deployment activities, we are looking for a Civil / Environmental Engineer to lead early-stage site development planning and civil infrastructure definition for future Oklo project sites.

In this role, you will own the development of conceptual site layouts, grading and drainage approaches, utility routing concepts, and preliminary civil works packages that support project siting, permitting, estimating, and execution planning. You will work cross-functionally with energy strategy, environmental, construction, operations, and project deployment teams to translate high-level project requirements into practical and buildable site concepts.

This position is ideal for someone who enjoys combining technical engineering judgment with fast-paced project development work and wants to play a foundational role in deploying next-generation clean energy infrastructure.

Specific responsibilities may include:

• Develop conceptual and preliminary site layouts for advanced reactor facilities and supporting infrastructure that includes harmonizing development with natural landscape features and ecological functions
• Design and develop industrial site layouts that integrate sustainability principles, incorporating natural features (e.g., topography, vegetation, drainage patterns) to optimize environmental performance, resilience, and regulatory compliance
• Generate early-stage civil works plans including grading, drainage, access roads, stormwater systems, underground utilities, laydown areas, and construction support facilities
• Support site feasibility studies, constructability evaluations, and site selection efforts
• Prepare estimates on overburden and spoils generated and cost estimates for civil and site development scopes
• Coordinate with environmental, geotechnical, structural, mechanical, electrical, and construction teams to ensure integrated site solutions
• Support permitting and environmental review activities, including coordination with local, state, and federal agencies
• Interface with external engineering firms, EPC partners, surveyors, and geotechnical consultants
• Develop technical specifications, scopes of work, and design criteria for civil engineering activities
• Support development of project schedules and execution strategies for site preparation and construction activities
• Participate in iterative design reviews and continuously refine site concepts as project requirements evolve
• Generate clear technical documentation, reports, drawings, and presentations supporting internal and external stakeholders
• Support construction planning, sequencing, and
