Modeling Scientist
Job Title: Modeling Scientist (Uncertainty Quantification)
Department: Modeling & Analytics
Reports to: Lead Modeling Scientist
Location: Remote
Base Salary Range: $100k - $160k base salary
The Modeling Scientist is responsible for improving model traceability, uncertainty quantification, and predictive trustworthiness in Arva’s ecosystem model predictions. This role is central to advancing Arva’s monitoring, reporting, and verification platform for greenhouse gas emission reductions and removals.
Working at the intersection of statistics, machine learning, and process-based ecosystem modeling, this role works closely with ecosystem modelers and data engineers to design robust model traceability and uncertainty frameworks that support transparent, decision-ready outputs for customers, partners, and environmental markets. The Modeling Scientist plays a critical role in translating scientific rigor into real-world impact through credible, auditable modeling systems.
Primary Job Responsibilities
Uncertainty Quantification and Model Evaluation
Generate and apply model traceability framework for ecosystem and biogeochemical models to enable rigorous model testing and improvements
Design and implement uncertainty quantification framework for the models, including parameter, structural, aleatory, and epistemic uncertainties
Apply sensitivity analysis, multivariate testing, and cross-validation to evaluate model robustness and generalizability across space and time
Quantify and communicate model confidence, uncertainty bounds, and performance metrics
Statistical and Probabilistic Modeling
Develop hierarchical and Bayesian approaches to support distributed and iterative model optimization
Apply probabilistic methods to integrate data, models, and uncertainty across scenarios
Analyze model outputs to diagnose limitations and inform model improvement strategies
Machine Learning and Model Integration
Integrate machine learning techniques with process-based or mechanistic models to improve predictive performance and scalability
Partner with data engineers to implement reproducible, scalable modeling pipelines
Contribute to the design of model evaluation and optimization workflows
Scientific Communication and Documentation
Communicate uncertainty, confidence intervals, and model performance clearly to internal teams and external stakeholders
Contribute to scientific reports, transparent model documentation, and peer-reviewed publications as appropriate
Support defensible, auditable model outputs suitable for regulatory and credit market review
Key Competencies / Requirements
5+ years demonstrated experience in uncertainty quantification, probabilistic modeling, and data model integration
Advanced proficiency in Python and scientific computing, with experience building reproducible modeling pipelines
Strong software engineering practices, including writing modular, testable, and well-documented code
Deep commitment to scientific rigor, transparency, and integrity
Experience integrating machine learning with process-based or mechanistic models preferred
Familiarity with ecosystem or Earth system models such as DayCent or CESM preferred
Familiarity with cloud platforms and data systems, including AWS and relational or spatial databases, preferred
Master’s or PhD degree or equivalent experience in Statistics, Applied Mathematics, Environmental Science, Earth System Science, Biology, or a related quantitative field
