Thanks for your interest in Oklo! We are searching for a Plant Process Simulation Engineer to join our engineering team. We are looking to fill this position immediately.

Position Description

Oklo is looking for an experienced process simulation engineer to be responsible for the development and ownership of the plant process simulation model for the Aurora power plant to inform design, operations, and plant dynamics.

Specific responsibilities may include

• Generate and own a plant process simulation model in AVEVA Process Simulation, ASPEN/HYSYS, Siemens Flomaster, or similar tool, that models and creates both transient and steady state plant performance results.
• Iteratively model existing and future plant equipment and maintain the model as new design parameters and drawings are produced.
• Establish automated plant model development to accelerate design decision making and inform plant economics and operations.
• Use equipment specifications and performance results to generate and implement detailed equipment component models.
• Work in cross disciplinary teams, including process engineering, instrumentation and control, power generation and distribution teams.
• Generate technical documentation and reports to be included in regulatory filings and internal/external technical reports showing plant and equipment performance.

Minimum Qualifications

• A bachelor’s degree in chemical, mechanical, nuclear, aerospace engineering or related engineering discipline
• At least 5 years of experience in the development or modeling of plant processes in the power generation, petroleum, chemical, or other similar industries
• Broad familiarity with engineering principles, with strong systems engineering and operations intuition
• Strong knowledge of plant thermodynamic cycle and process fluid modeling at an equipment and plant-level

Bonus Qualifications

• Experience with building power conversion system process simulation models
• Experience with designing process systems in power or chemical industries
