About The Position

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.

Requirements

Bachelor’s degree in Civil Engineering, Environmental Engineering, or related discipline
5+ years of relevant engineering experience in industrial, energy, infrastructure, environmental, or site development projects
Experience developing site layouts, grading plans, utility concepts, and civil design packages
Familiarity with civil engineering design tools such as Civil 3D, AutoCAD, GIS platforms, or equivalent
Experience preparing conceptual cost estimates and quantity takeoffs
Understanding of stormwater management, drainage design, and utility coordination
Familiarity with applicable codes, standards, and permitting processes
Ability to travel occasionally to project and development sites
Professional Engineer (PE) license or Engineer in Training (EIT) with expectation of PE certification

Nice To Haves

Experience with nuclear, industrial, energy, or mission-critical infrastructure projects
Experience supporting environmental permitting or NEPA processes
Familiarity with geotechnical investigations and site characterization activities
Experience coordinating with EPC contractors and construction teams
Experience with construction field engineering or construction management
Knowledge of DOE, NRC, OSHA, EPA, or state environmental regulations
Experience working in startup or highly iterative engineering environments

Responsibilities

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 field execution activities as projects mature
