ABOUT THE ROLE

TransAlta is recruiting a Thermal Performance Engineer to support and advance the effectiveness of our corporate Performance and Reliability function. This role is a senior technical contributor responsible for improving asset performance across our generation portfolio, with primary focus on thermal assets.
