Fullstack Engineer

Join the Market Leader in Electric Power Data and Analytics Solutions

The electrical grid is the largest and most complicated machine ever built. Yes Energy’s industry‑leading electric power trading analytics software provides real‑time visibility into the massive amount of data generated by the North American electrical grid daily. Our unique and innovative view of the data informs real‑time trading decisions and mid‑to‑long‑term investment decisions that keep utility prices low, support the energy transition, and keep the grid running.

It’s both challenging work and work with a purpose.
