Sr. Software Development Engineer – Amazon – Toronto, ON
Location: Toronto, ON | Company: Amazon
Amazon’s Advertiser Growth Tech team is looking for a Senior Software Development Engineer to join the Portal Experience team in Toronto, Ontario. This is a high-impact role at the intersection of distributed systems, large-scale advertising platforms, and personalized user experience — directly shaping how over two million daily advertisers interact with Amazon’s marketing portals.
You’ll be working on the next generation of self-service marketing experiences across Seller Central, Amazon Ads Console, and other key advertising portals. This isn’t just a coding role — it’s an architectural leadership position where your technical decisions will influence systems at a scale that few engineers ever get to work with.
About the Role: Sr. Software Development Engineer, Advertiser Growth Tech
As a senior engineer on a focused two-pizza team, you’ll architect and own high-throughput, low-latency systems that power personalized marketing experiences for millions of advertisers daily. You’ll navigate complex integrations between first-party Amazon services and third-party platforms — including CMS platforms, targeting systems, and data orchestration tools — while driving system design discussions and making architectural trade-offs that align performance with business value.
Beyond the code, this role calls for a strong technical leader who can mentor engineers, establish engineering best practices, and build consensus across product managers, platform teams, and marketing stakeholders. You’ll own projects from initial design through deployment and ongoing operations, balancing short-term delivery needs against long-term architectural vision.
Benefits and Salary
The base salary range for this position in Toronto, ON is $150,700 to $251,700 CAD annually. Amazon’s total compensation package may also include sign-on payments and restricted stock units (RSUs), with final compensation based on experience, qualifications, and location. Benefits include health insurance (medical, dental, vision, prescription, and basic life & AD&D), a Registered Retirement Savings Plan (RRSP), a Deferred Profit Sharing Plan (DPSP), paid time off, and additional resources to support health and well-being.
