Google is looking for a Staff Site Reliability Developer to join the Google Unified Security and Threat Operations team in Waterloo, Ontario. This is a senior-level engineering role sitting at the intersection of software development and systems engineering — where the problems are genuinely complex and the scale is unlike almost anywhere else in the industry.

As part of Google Cloud's Site Reliability Engineering (SRE) organization, you'll be responsible for the full lifecycle of large-scale, massively distributed systems — from initial design through deployment, live operations, and continuous improvement. The work spans everything from capacity planning and launch reviews to automation, incident response, and performance monitoring.

About the Role: Staff Site Reliability Developer

This role is squarely focused on keeping Google Cloud's services — both internal and customer-facing — reliable, performant, and continuously improving. You'll engage directly with system design, build software platforms and frameworks, and help scale infrastructure sustainably through automation. Much of the day-to-day work involves optimizing existing systems, building shared infrastructure, and eliminating toil so that engineering teams can move faster with confidence.

Google's SRE culture places a strong emphasis on intellectual curiosity, psychological safety, and blameless postmortems. You'll work alongside people with diverse backgrounds and perspectives, encouraged to think big, take calculated risks, and self-direct meaningful projects. The team also values mentorship and growth — both giving and receiving it.

Benefits and Salary

This position offers a competitive annual salary ranging from $216,000 to $221,000 CAD, along with a 20% bonus target, equity, and a comprehensive advantages package. For full details on Google's benefits offerings, visit Google's careers benefits page.
