Job 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.

Key Responsibilities

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.

Requirements

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
Experience with building power conversion system process simulation models
Experience with designing process systems in power or chemical industries
We are looking for a Plant Process Simulation Engineer that is:
Passionate about clean energy
Passionate about making advanced fission a reality
Willing and able to learn quickly
Willing to think differently and do things in new ways
Comfortable in a fast-paced, highly iterative environment
Excited to think creatively, critically, and reflectively about the problems they are solving while not leaning only on what has been done before
Willing to propose novel and creative solutions to technical problems
Able to communicate technical content and results both verbally and in writing
A startup person : You aren't driven by titles or hierarchy, and prefer efficiency to excess process. You don't need or expect to have a lot of guidance but you enjoy working in a fast-paced team. If you prefer the culture and feel of a large organization, that is great, but you likely won’t enjoy working with us! There is plenty of important work and plenty of good opportunities with organizations like that.
Motivated : You are self-motivated. You bring an enthusiasm to the team, and imbue a sense of passion that goes beyond clocking in and clocking out. This isn’t about a fake or arbitrary “pieces of flair” mentality or lack of work-life balance! It is about being a part of the vision and feeling a part of reaching team goals.
A team-player : Oklo genuinely is a team. We aren’t about taking credit for ourselves, and we aren’t about pushing blame to others. We do incredible things because we work as a team.
An excellent communicator : We need a person who is not only technically competent but also a clear and upbeat communicator.
Creative : Being creative means that when things fall outside clear scopes or processes or problems arise without clear solutions, you are able to identify it as well as invent ways to solve a problem or fill a need without micromanagement. The successful person in this job will not only be creative, but also enjoy being creative and solving open-ended problems which may change day-by-day.
Detail-oriented : This focus is a big part of excellence, consistency, and quality. Excellent grammar and spelling matter for both good communication as well as the image of the company that we put forward.
