About the Machine Learning Engineer 

You love building smart, scalable systems that convert streams of data into critical insights and actions. Sometimes this means wearing a data scientist hat, developing learning algorithms that power our customer portal and business decisioning systems, but most frequently it means donning a data engineer’s hat, building and scaling the applications that host these models in the cloud. You bring on-the-job experience with the technologies and architectures that make for fast and robust data pipelines, capable not only of structuring and transforming data but validating and alerting on it as well. You also bring experience with cloud-based distributed computing frameworks and are ready to lead the data science team’s efforts to scale up its entire portfolio of data-driven applications.   

Beyond your technical interests, you have a passion for sustainability and are eager for your work to support the advancement of clean energy and enabling technologies, such as distributed energy resources and demand response. You want to become an expert in energy market operations, from load forecasting to management, but also in the digital experience of our customers, to ensure that they have an effortless and rewarding relationship with clean energy. Above all, you have strong communication skills, are able to engage effectively with non-technical stakeholders of your work, and are ready to learn from others and share your own expertise.
