Actively hiring Posted 4 months ago

Responsibilities

  • Design, develop, and deploy high‑quality time series forecasts for energy market prices, ancillary services, energy demand, and renewable generation (e.g., solar PV and wind).
  • Apply a broad range of forecasting methodologies, including classical statistical models, machine learning, and deep learning approaches, selecting methods appropriate to data regimes and business constraints.
  • Lead feature engineering efforts incorporating calendar effects, weather signals, exogenous drivers, and regime changes.
  • Establish rigorous model evaluation, backtesting, and benchmarking frameworks to ensure accuracy, robustness, and stability over time.
  • Architect, build, and maintain end‑to‑end MLOps pipelines, covering data validation, training, versioning, deployment, monitoring, and retraining.
  • Ensure forecasting systems are scalable, observable, and reliable in production, with clear SLAs, alerting, and rollback strategies.
  • Partner in the design and evolution of an internal forecasting platform that supports the full machine learning lifecycle and multi‑model production hosting.
  • Implement best practices for model governance, reproducibility, experiment tracking, and lineage.
  • Conduct applied research to identify new modeling techniques, architectures, and tooling that improve forecast accuracy, latency, and operational efficiency.
  • Translate research ideas into production‑ready solutions, balancing innovation with maintainability.
  • Influence technical roadmap decisions related to forecasting systems, data platforms, and MLOps standards.
  • Work closely with engineering, product, and domain experts to ensure forecasting solutions deliver measurable business and operational impact.
  • Incorporate energy system constraints and domain knowledge into models to ensure outputs are physically meaningful and actionable.
  • Support production operations by troubleshooting issues, analyzing model degradation, and continuously improving system performance.

Basic qualifications

  • Master’s or Ph.D. in statistics, machine learning, applied mathematics, computer science, or a related quantitative field.
  • 5+ years of hands‑on experience in data science or machine learning, with significant exposure to time series forecasting in production.
  • Strong proficiency in Python and experience writing production‑quality, maintainable code using modern software engineering practices.
  • Deep theoretical and practical knowledge of time series methods, including statistical, regression‑based, and deep learning approaches.
  • Demonstrated experience building and operating ML systems in production, including CI/CD for models, monitoring, and lifecycle management.
  • Experience with cloud‑hosted platforms (preferably Azure / Fabric), containerization, and distributed compute.
  • Proficiency with core data science and ML libraries such as pandas, numpy, statsmodels, sklearn, xgboost, lightgbm, pytorch, keras, and modern forecasting libraries (e.g., Nixtla).
  • Strong problem‑solving skills, ownership mindset, and ability to operate effectively in ambiguous, real‑world environments.
  • Travel may be required up to 10%, depending on business needs

Preferred qualifications

  • Experience with energy systems, electricity markets, or infrastructure forecasting, including demand, pricing, or renewable generation.
  • Familiarity with power systems concepts such as unit commitment, economic dispatch, or grid constraints.
  • Prior experience designing or contributing to forecasting platforms or shared ML infrastructure.
  • Exposure to large‑scale data pipelines, streaming or batch processing, and data quality frameworks.
  • Experience collaborating across data science, software engineering, and operations teams in a production environment.
  • This target salary range is for CA positions only and should not be interpreted as an offer of compensation.
