About Us

At Opower, part of Infrastructure Industries GIU, we build and operate SaaS solutions to transform how people interact with their utility (providers of electricity, gas and/or water) and how utilities interact with their customers. Improving the relationship between Utility and Customer is a key building block of our mission “To provide the best solutions for the world’s energy and water challenges.”  Via SaaS solutions built on Oracle’s next-generation cloud infrastructure (OCI), we focus on speedy delivery of utility-specific services, increase corporate administration efficiency, and turn business data into business intelligence.

Opower Platform & Communications Group Overview

Originally a start-up acquired by Oracle in 2016, Opower has retained its innovative energy and mission-driven culture. We use utility data and behavioral science to help people save energy through a comprehensive product suite across various communication channels and a modern web platform. Our group, Platform & Communications, is focused on building products that educate our customers about their energy, water, or other utility usage via our machine-learning driven insights and nudge customers to become more efficient and flexible with their usage. These products have saved over 31 Terawatt-Hours of electricity and avoided 15.2 million metric tons of carbon in our atmosphere! Our products need to continue to scale to serve even more customers and provide increased flexibility with the communications we send. These represent big challenges that will require critical thinking and innovative engineering. We are very mission-driven and are looking for an engineer who shares this mission to join our team!
