About The Position

ecobee, now a subsidiary of Generac Power Systems, is seeking a Software Engineer to join their Device Management Services team. This team is responsible for building and maintaining distributed backend systems that handle large-scale IoT device connectivity, onboarding, authentication, authorization, and persistent communication between devices and cloud-based applications. The role involves contributing to the design and development of highly scalable, fault-tolerant backend services that power real-time device communication and orchestration. The engineer will work with modern distributed systems as well as existing large-scale Java-based monolithic systems. This is a high-impact engineering role at the core of Generac’s connected device ecosystem, working on systems that power millions of IoT devices and enable real-time intelligence, control, and automation. The position offers the opportunity to work with modern cloud-native architectures and influence the evolution of foundational systems for next-generation IoT capabilities. The role follows a hybrid schedule, requiring in-office work on Wednesdays and Thursdays in the Toronto office, with flexibility to work remotely for the remainder of the week.
