Data Scientist – Staff or Senior
KoBold Metals
• Help develop KoBold’s proprietary software exploration tools. • Find and curate geophysical, geochemical, geologic, and geographic data and integrate it into KoBold’s proprietary data system. • Build models to make statistically valid predictions about the locations of compositional anomalies within the Earth’s crust. • Create effective visualizations for evaluating model performance and enabling rapid interaction with the underlying data and key features. • Develop and apply data processing, statistical, and physics-based techniques to geoscientific data — from computer vision to geophysical inversions — and use the results to guide our targeting efforts and inform our acquisition and exploration decisions. • Present to and collaborate with our external partners and stakeholders.
Job Requirements
- An advanced degree in the physical sciences, engineering, computer science, or mathematics.
- A minimum work experience of 4 years post PhD or 8 years post MS, ideally as a data scientist or data engineer.
- Experience leading technical teams to apply novel scientific approaches to core business problems.
- Technical skills, including extensive experience with Python’s data science packages and general software engineering practices.
- Collaborative software development (git), and familiarity with software engineering best practices like unit test/integration test suites, and CICD pipelines.
- Cloud computing resources.
- Building predictive models, applying them to different problems, and evaluating and interpreting the results.
- Data from a variety of physical systems.
- Geospatial analyses and visualizations.
- Broad skills in and knowledge of applied statistics and Bayesian inference.
- Substantial understanding of machine learning algorithms.
