Senior Software Engineer

Hi, we are ecobee.

ecobee introduced the world’s first smart Wi-Fi thermostat to help millions of consumers save money, conserve energy, and bring home automation into their lives. That was just the beginning. We continue our pursuit to create technology that brings peace of mind into the home and allows people to focus on the moments that matter most. We take pride in making a meaningful difference to the environment, all while being part of the exciting, connected home revolution.

In 2021, ecobee became a subsidiary of Generac Power Systems. Generac introduced the first affordable backup generator and later created the category of automatic home standby generator. The company is committed to sustainable, cleaner energy products poised to revolutionize the 21st century electrical grid. Together, we take pride in making a meaningful difference to the environment.

Why we love to do what we do

We’re helping build the world of tomorrow with solutions that improve everyday life while making a positive impact on the planet. Our products and services work in harmony to provide comfort, efficiency, and peace of mind for millions of homes and businesses. While we’re proud of what we’ve done so far, there’s still a lot we can do—and you can be part of it.

Join our extraordinary team.

We're a rapidly growing global tech company headquartered in Canada, in the heart of downtown Toronto, with an office in Leeds, UK, and remote ecopeeps in the US. We get to work with some of North America and UK's leading professionals. Our colleagues are proud to bring their authentic selves to work, confident that what we do is grounded in a greater purpose. We’re always looking for curious, talented, and passionate people to join our team.

Who’ll You Be Joining

The Energy Services team’s vision is for thoughtful homes to work together for 100% clean and affordable energy. Our team is entirely focused on planet positivity, and you will be a key contributor in bringing that vision to life. eco+ has already helped millions of users use cleaner and cheaper energy and is growing fast to keep energy costs low for more homeowners across North America.

The eco+ product is used by more than 70 utility partners and is revolutionizing how the grid responds to peak demand, thanks to Machine Learning models that optimize comfort and energy savings for customers. At the heart of this is the Energy Control Platform (ECP), ecobee's API platform that enables utility partners to create and manage demand response and grid resiliency programs, dispatch events to enrolled smart thermostats, and manage thermostat groups at scale.

You would be joining as a member on a small but growing team, helping shape a culture that empowers the team to make great technical decisions, drive strategic choices, actively improve on our processes and mentor others.

You will work closely with Product and other engineering teams to shape the roadmap and consistently improve the platform, with occasional collaboration with marketing and sales partners.

The Energy Services team is highly data driven an is consistently focused on improving our culture and processes. You’ll benefit from monthly learning days, regular guest speakers from the energy industry, strategic offsites, as well as other opportunities for growth and development!

This role follows a hybrid schedule, with in-office work required on Wednesdays and Thursdays to support collaboration, and flexibility to work remotely for the remainder of the week.
