Contract Geohazard Scientist - Earth Science, Geology, Python, Machine Learning About the role We are looking for a skilled scientist on a contract basis with expertise in geophysics or remote sensing hazard modelling to join our team. In this role, you'll contribute to the development and expansion of our in-house landslide and subsidence risk models, helping to extend their application to new geographic regions. As part of a collaborative, multi-disciplinary Science Team, you'll work alongside experts in climate science, machine learning, and natural hazard modelling. This position is well-suited to someone experienced in working with large, complex geospatial datasets, with a proven track record of training and validating machine learning models for production use. If you're excited about applying your skills to advance cutting-edge hazard modelling, we'd love to hear from you. The impact you'll own Geohazards model development and implementation: You'll be spearheading the research and implementation of our existing geo hazard machine learning models as we expand into new regions. You'll be tasked with acquiring training and validation data for these models from diverse open-source data sources. Fine-tune and future-proof our models: Take ownership of calibrating and validating models to meet the highest scientific, practical, and regulatory standards. You'll ensure these models perform seamlessly at a continental scale, empowering clients with useful and reliable risk assessments. Bring creativity to validation challenges: Use your hazard modelling expertise to tackle qualitative validation in innovative ways, especially when data is scarce. Your insights will help us push boundaries and improve outcomes. Lead with vision and expertise: Showcase your technical prowess by documenting and presenting models for scientific peer review. Collaborate with stakeholders to shape the future of our geohazard solutions and drive innovation at every step. A key output of your work will be technical and qualitative validation reports of your model for regulatory purposes.
