We’re Hiring: Cool Farm – Methods Modeller

Cool Farm is looking for a new Methods Modeller, with a sharp mind, who is passionate about climate change and sustainability impacts, and who is motivated to grow with us and support our continued success for the long run.

Company description:

The Cool Farm Alliance (CFA) is a science-led, not-for-profit membership organisation that owns, manages and improves the Cool Farm Tool (CFT), which is used to measure on-farm environmental sustainability. Usage of both the CFT and membership of the CFA has grown rapidly, establishing itself as a globally leading quantification tool and platform.

As the momentum for sustainability grows amongst the world’s leading food and beverage companies, an increasing number of CFA members are stepping into strategies that incorporate regenerative agriculture to help deliver their net zero and broader sustainability goals.

The translation of peer reviewed science into robust and meaningful methodologies for our quantification calculations is a key foundation for our work as an Alliance. This in turn is essential for maintaining credibility and trust in our calculation tools.

The CFA is now looking for a Methods Modeller, with a sharp mind, who is passionate about climate change and sustainability impacts, and who is motivated to grow with us and support our continued success for the long run. The role will focus on developing models of carbon stocks and flows across agricultural systems, including crops and livestock, using the latest peer-reviewed evidence, open source and procured data, with an initial focus on soils. These models will be used to support our work in building a scientifically credible and robust cool farm tool GHG assessment pathway.

As an ideal candidate you will have a background/education in mathematical modelling with experience in ecological and/or climate science. You will have strong analytical skills and be experienced in handling and presenting data in a clear, concise, and accurate manner. You will report to Cool Farm Alliance’s Science and Methods Manager.

If you have a background in science, are intelligent, personable, love numbers, have outstanding attention to detail, organisational skills and a solid work ethic, we would love to hear from you.

The role:

  • Effective Conversion of Scientific Guidance into Code
    • Reviewing different modelling options and advising on approaches to take, working with the product team to enable development delivery of our digital calculation tools.
    • Development of calculations and models written in Python.
    • Delivery of greenhouse gas assessment methodologies, including GHG calculations, emissions and removals estimation modelling and uncertainty assessments.
    • Support the process of identifying credible science sources and translating these into credible quantification methods and models that support an enjoyable user experience in support of the transition to more regenerative agriculture.
  • Quality Control and Data Accuracy
    • Contribute to product testing and provide recommendations on new features for our product development.
    • Work with the Science & Methods Manager, Product Manager and Technical Manager to develop detailed user and technical specifications for adding new methods to the CFT.
    • Quality assurance and technical description of calculations and models developed.
  • Collaboration and Communication
    • Working with our Cool Farm development team to deliver new methods into our Cool Farm Platform.
    • Coordination of methods sub-contractors.
    • Support our team with technical and project management queries.
    • Participation in and coordination of member working groups.
    • Provide technical insights and explanations of the methods and their development.
    • Support regular communications, both internal to the working group and external to the wider membership, keeping stakeholders updated on development progress.

Critical success factors:

  • Effective Conversion of Scientific Guidance into Code: The ability to efficiently and accurately translate scientific guidance related to carbon stocks and flows in agricultural systems into functional code is essential. Success in this role hinges on the ability to develop models that align with the latest peer-reviewed evidence and methodologies.
  • Quality Control and Data Accuracy: Success as a Methods Modeller requires an extremely keen attention to detail and a rigorous approach to quality control and testing of data models. Ensuring the accuracy of calculations, emissions, and removals estimation models is crucial for producing scientifically credible and robust greenhouse gas assessment methodologies.
  • Strong Collaboration and Communication: The role involves working closely with cross-functional teams, including the product team, member working groups, and sub-contractors. Critical success lies in effective collaboration, communication, and coordination with these teams to deliver digital calculation tools, greenhouse gas assessment methodologies, and technical descriptions of models. Additionally, the ability to communicate complex scientific concepts in a clear and concise manner to audiences is vital.

Knowledge, experience & capabilities:

Essential requirements

  • Have a higher degree (Masters or PhD) or with minimum five year’s work experience in a relevant role, such as geographic, ecological or climate sciences.
    • Experience in environmental modelling and programming with Python or a similar language to construct models of environmental change.
