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.
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.
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. 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 be working closely with the marketing and sales teams, hearing client feedback firsthand, allowing you to collaborate with the Product Manager to consistently improve the product and the roadmap.
The Energy Services team is highly data-driven and 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 from our Toronto office to support collaboration, and flexibility to work remotely for the remainder of the week.
How You'll Make an Impact:
As a Senior Backend Engineer, you'll:
-
Design, build, and evolve high-load, highly concurrent backend services that directly support ecobee's products and business goals.

Use modern technologies to solve complex technical challenges at scale, with the flexibility to evaluate and adopt new tools when they meaningfully improve outcomes.
-
Contribute to and help shape ecobee's engineering culture by sharing knowledge, learning from peers, and applying thoughtful engineering practices.

Influence technical direction and decision-making, with your ideas and contributions having a measurable impact on the company's systems and objectives.
Our team believes strongly in operational excellence — we take full ownership of the services and systems we build, right through to production. From monitoring and troubleshooting our services running in the cloud, to analyzing real-time fleet metrics and responding to incidents, you'll be part of a culture where reliability is a shared responsibility and on-call is a point of pride, not a burden.
What You'll Bring to the Table:

-
You're fluent in Go, our primary backend language, and comfortable using Java, Python, or JavaScript when needed.

You're open to learning new technologies when it helps you deliver solutions more effectively.
-
You thrive on large, complex challenges and are comfortable working with issues of scale, concurrency, large data sets, security, redundancy, and failover—key considerations for a successful IoT platform.
-
You have strong experience designing, implementing, and debugging microservices using Google Cloud Platform and/or AWS, along with both NoSQL and relational databases.
-
You value the craft of software development and actively practice automated testing, CI/CD, and sound design patterns.
-
You understand the full lifecycle of getting code to production—from review and merge through deployment in the cloud or a data center—and can identify opportunities to improve reliability and delivery.
-
You care deeply about system stability and customer experience, which includes working with metrics, participating in a healthy on-call rotation, and building robust, resilient systems.
-
You prioritize the team by providing mentorship, support, and guidance, while helping focus efforts on the highest-impact work and supporting overall team well-being.
AI‑Assisted Development Expectations

Hands-on experience using AI tools (e.g., Claude, Copilot, or similar) in real development workflows.
-
Ability to critically assess AI output and validate it with tests, reviews, and incremental rollout.
