Sr.SoftwareDevEngineer,WebExperiences

With AI reshaping every layer of the software stack, the tools engineers use to build, test, and ship software are being reimagined — making them faster, more automated, and more reliable than ever. The Amazon Web Experiences Infrastructure (WEI) team is looking for a Senior Software Development Engineer to join our ranks. Join our team to design and operate the scalable, reliable systems that compile and test software dependent on Chromium — the world's largest open-source project — across Amazon, powering Amazon WebView, the Silk browser, and a growing set of Chromium-based products. You'll rethink how an entire engineering organization builds and verifies Chromium-based software at scale, and take the lead on how rapidly evolving AI transforms developer productivity and software quality. You'll collaborate with talented engineers, product managers, and partner teams to solve complex distributed-systems and developer-experience challenges while directly impacting how engineers build the browsing experiences that reach millions of Amazon devices. Key job responsibilities - Design and operate the scalable, reliable systems that compile and test software dependent on Chromium across Amazon — owning API contracts, data models, and the scaling, latency, and availability budgets that thousands of builds depend on every day - Drive AI-led innovation that raises developer productivity and software quality — shifting testing left to advance our vision of fully automated CI/CD from commit to release - Debug and optimize reliability, latency, and data-consistency issues across distributed build and test services — including our device farm and device lab integrations — to ensure fast, trustworthy feedback for the engineers building Chromium-based products - Collaborate with client teams (Silk, Amazon WebView, Vega, and other Chromium consumers across Amazon), product managers, and partner teams to understand their build and test requirements and deliver self-service infrastr
