About the role

CREW Carbon is on a mission to remove billions of tons of carbon dioxide from the atmosphere. CREW’s technology enhances the natural power of minerals to treat wastewater and store CO2 permanently, all while optimizing pH and alkalinity, improving nutrient removal rates, and reducing costs for municipalities’ wastewater treatment plants. As a Senior Modeler, you will play a crucial role in developing and applying dynamic and mechanistic biogeochemical models to predict weathering rates and track the fate of weathering products in river and ocean systems. Your work will help advance CREW Carbon’s innovative technology and support our mission of large-scale carbon dioxide removal.

Responsibilities

Biogeochemical modeling:

  • Develop and implement dynamic and mechanistic biogeochemical models using Python, R, MATLAB, and other coding languages.
  • Predict weathering rates of various minerals and track the fate of weathering products in river and ocean systems while modeling biogeochemical interactions (e.g., carbonic acid system dynamics, air-gas exchange, nitrification, bioflocculation, etc.)
  • Use and refine existing dynamic river network models and ocean models (e.g., cGENIE, ROMS) to monitor storage of stored CO2 in rivers and oceans.
  • Leverage large datasets and apply machine learning techniques to enhance the predictive capabilities of geochemical models.
  • Collaborate with the research and engineering teams to integrate geochemical models into CREW’s technology platform.
  • Analyze and interpret model results to inform strategic decision-making and technology development.

Data analysis and integration:

  • Collect and analyze geochemical, hydrological, and environmental data to support model development and validation.
  • Integrate field and laboratory data into geochemical models to improve accuracy and reliability.
  • Work with data scientists and engineers to enhance data processing and analysis workflows.

Research and development:

  • Conduct literature reviews and stay updated on the latest advancements in geochemical modeling, carbon cycle, geochemical kinetics, and oceanography.
  • Identify and propose new modeling approaches and techniques to enhance CREW’s technology.
  • Collaborate with academic and industry partners on research projects and publications.

Documentation and reporting:

  • Prepare technical reports, presentations, and scientific publications to communicate model results and findings.
  • Document modeling methodologies, assumptions, and results for internal and external stakeholders.
  • Present findings at industry conferences, meetings, and workshops.

Requirements

  • Strong background in geochemistry, computational modeling, environmental science, or a related field.
  • Proven experience in geochemical modeling and simulation using Python, MATLAB, R,  or similar coding languages.
  • Familiarity with hydrological and oceanographic modeling techniques and programs, such as ROMS, cGENIE, Geochemist’s Workbench, PHREEQC, SUMO.
  • Strong understanding of the carbon cycle, geochemical kinetics, and oceanography.
  • Experience with machine learning techniques and leveraging large datasets for predictive modeling.
  • Strong communication and teamwork skills.
  • Ability to thrive in a fast-paced, rapidly changing startup environment where priorities can shift on a monthly basis.
  • You practice extreme ownership (no task is too small).
  • You love being in the trenches with your team and working with high empathy.
  • You have a growth mindset.
