About the Role

As a senior applied ML practitioner, you will own the full lifecycle of forecasting and optimization models, from data pipelines and feature engineering through model training, deployment, monitoring, and production support. This work matters, as optimizing power utilization has a huge impact on customers, the electrical grid, and the environment. We offer exciting opportunities for conferences, continuous learning, and professional development on a cutting-edge platform with no tech debt.

Responsibilities

  • Implement and maintain secure, reliable, and scalable data pipelines for data science projects and real-time energy grid data.
  • Own the full lifecycle of time-series forecasting models, including data preparation, feature engineering, model training, validation, deployment, monitoring, retraining, and production support.
  • Develop, train, tune, and operate Temporal Fusion Transformer models and other time-series forecasting approaches for energy market, grid, asset, and customer use cases.
  • Deploy machine learning models into production using practical MLOps patterns, including reproducible training workflows, model versioning, inference pipelines, monitoring, and rollback strategies.
  • Build and maintain Airflow DAGs to orchestrate data ingestion, model training, batch inference, validation, and downstream reporting workflows.
  • Diagnose and troubleshoot data quality, model performance, and pipeline reliability issues, implementing durable fixes.
  • Support disaster recovery and operational readiness for critical data pipelines, model workflows, and production forecasting systems.
  • Monitor and report on data pipeline health, data quality, model performance, forecast accuracy, drift, and production incidents.
  • Establish transparent tracking for model experiments, training runs, deployment status, and operational performance.
  • Create dashboards, alerts, and documentation to make production data and ML systems understandable to stakeholders.
  • Collaborate with software teams to understand and document data sources from production applications.
  • Collaborate with stakeholders to integrate models, forecasts, and data into production applications.
  • Provide technical guidance and coaching to influence the design, development, and testing of cloud applications that produce data.
  • Continuously improve the reliability, scalability, observability, and performance of data pipelines and production ML systems.
  • Stay current with advances in time-series forecasting, MLOps, cloud data platforms, and energy analytics.
  • Apply a pragmatic, production-focused mindset to model development, balancing accuracy, interpretability, maintainability, and operational value.

Requirements

  • Strong analytical and problem-solving skills to find solutions to complex problems and drive high-risk initiatives to completion on time and on budget.
  • Experience deploying and maintaining containerized cloud applications (e.g., Docker) and cloud functions (e.g., AWS Lambda).
  • Experience working with relational and time series databases, like Postgres, TimescaleDB, ClickHouse, and InfluxDB.
  • Experience with data workflow orchestration tools such as Apache Airflow or Luigi.
  • Experience with MLOps platforms such as Kubeflow, AWS SageMaker, or Google Vertex AI.
  • Experience with infrastructure-as-code software such as Terraform or Pulumi.
  • General knowledge of software development, APIs, data stores, networking, security, machine learning, and cloud computing services.
  • Self-sufficient in troubleshooting and resourceful in uncovering mysteries.
  • Continuously learning new frameworks and technologies to generate innovative solutions.
  • Curious, striving first to understand before being understood.
  • Strong analytical skills to find solutions to complex problems and drive initiatives.
  • Excels when collaborating with a small team using an agile process.
  • Great communication and collaborative problem-solving skills.
