Title:  Process Modeling Engineer

Company: GreenFire Energy Inc.

Reports to:  Chief Modeling Engineer

Location: GreenFire Energy is located in the San Francisco Bay Area, CA, but the principal work location can be discussed. Some travel will be required.

Compensation: Competitive salary, employee stock options

Contact: . Put “Process Modeling Engineer” in the subject line.

Position Summary

GreenFire Energy designs and builds geothermal power projects worldwide using its proprietary closed-loop geothermal technology (“GreenLoop”). GreenLoop requires sophisticated site-specific design and engineering to optimize power generation from a wide spectrum of geothermal resources.

The Process Modeling Engineer will perform thermodynamic power cycle process modeling for GreenFire Energy’s “GreenLoop” geothermal energy systems including gas and liquid flow conditions, both downhole and at the surface. Accurate power cycle modeling will consider geophysical attributes, turbines, heat exchangers, pumps, compressors, and pipe flow. Working fluids include water, CO2, and various ORC refrigerants. Results will then be used for modeling optimization and customer proposals; e.g., power costs, material costs, O&M costs, and LCOE calculations.

Job Responsibilities

  • Work with customer personnel to obtain detailed well and resource information for modeling purposes. This process may include travel to customer sites.
  • Understand, update, modify, optimize, and advance the Company’s existing process and financial modeling for the company’s geothermal energy systems.
  • Apply the company’s modeling tools to geothermal well data provided by customers to assess the optimal configuration of equipment and processes for power generation.
  • Work closely with the company’s project developers to assess project opportunities and select alternatives for customer proposals.
  • Participate in the preparation of formal customer proposals and assist in the presentation and sales process for such proposals.
  • Develop, maintain, and enhance all company modeling tools.
  • Participate in preparation of additional method and system patents to capture advances in the company’s technology.

Education and Experience

  • Bachelors or Master’s Degree in Chemical/Mechanical Engineering, Applied Mathematics, or any other closely related field.
  • Demonstrated experience in advanced quantitative analysis and process modeling.
  • Exceptionally strong analytical, process engineering, and problem-solving capabilities.
  • Proficient in using programming languages such as MATLAB, Python, R.
  • Experience in computational modeling (Finite Element Method), regression modeling, supervised and unsupervised learning models (preferred, but not necessary).   
  • Strong personal and interpersonal skills.
  • Entrepreneurial mindset.
