ISO New England is the independent system operator responsible for ensuring the safe and reliable flow of electricity in our region and planning for the future of the electric grid. We are at the forefront of New England’s ongoing transition to clean energy.

New technologies and the New England region’s economy‑wide decarbonization efforts are driving a profound transformation in the work of the Forecast Group within System Planning. Responsible for analytics and predictive modeling of the region’s electricity demand across all timescales—spanning both short‑term and long‑term time horizons—the Forecast Group is innovating and redesigning its forecasting methods, software, and tools to meet changing trends in how retail customers procure, manage and use electricity.

This role requires a self‑starter with demonstrated ability to work seamlessly both unsupervised and in a fast‑paced, collaborative team environment. This position will be focused on long‑term forecasting, with potential opportunities to work in long‑range forecasting as well. The candidate will have an opportunity to lead the team’s development of next generation forecasting tools that are integral to the planning and operation of the future grid.

NOTE: This role is currently located in Windsor, CT until it permanently moves to Holyoke, MA, which is currently expected to occur in 2028.

• Distance‑based relocation assistance available

How you will make an Impact

• Work independently and collaboratively on analytical, programming, modelling, and data management activities
• Map out and document problem statements, project requirements and associated workflows in pursuit of efficient and effective solutions
• Leverage a curious mindset, initiative, and “elbow grease” to enhance existing processes, and to innovate new forecasting methods, tools, and software
• Communicate complex, technical content to a diverse audience through written reports and presentations
• Apply a persistent drive for quality results to lead the development of data pipelines, reusable software packages and visualizations
• Stay current with forecasting research and industry best practices; evaluate and implement relevant approaches strategically

• Proficiency in at least one advanced programming language such as Python, R, MATLAB, or SAS
• Hands‑on experience developing software in a collaborative team environment
• Experience working with big data, geospatial analytics, and/or probabilistic forecasting
• Experience building applications that ingest and use data from multiple sources and formats (i.e., data wrangling/data munging).
• 5+ years of relevant experience is required to be considered for a senior‑level position. 7+ years of relevant experience is required to be considered for a lead‑level position.
• Excellent written and verbal communication skills
• Desired but not required:
  • Experience in electricity consumption modelling or economic modelling in the energy sector
  • Knowledge about distributed energy resources (e.g. photovoltaics, batteries), electric vehicles, and/or cold‑climate heat pumps
