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 infrastructure that meets their needs
- Document your work, maintain existing services, and raise the operational bar — participating in code reviews, architectural discussions, and technical planning to continuously improve how Chromium is built and verified at Amazon
A day in the life
As a Senior Software Engineer on the Web Experiences Infrastructure team, you'll work across the build, test, and release stack, shaping the architecture of the systems that compile and verify Chromium-based software at Amazon scale. Your day might include designing pipeline and service APIs and data contracts, decomposing monolithic build architecture into distributed, independently-owned builds, prototyping how AI can shift testing left and eliminate manual steps from the release process, debugging reliability and data-consistency issues across our distributed services and device farm, collaborating with client teams to understand their workflows, and reviewing code from teammates. You'll have the autonomy to identify the highest-impact problems, propose solutions, and see your work deployed to real internal customers in a fast-paced environment that values both rapid iteration and thoughtful engineering.
About the team
We're a collaborative group of engineers who operate with startup mentality within a global organization. Our mission is to provide Amazon engineers with the best tools for building and verifying Chromium-based products on any device — maintaining highly available continuous delivery systems that verify changes accurately and efficiently across Amazon's device ecosystem. We set the bar for operational excellence, make developers productive by simplifying and automating development processes, and prioritize efficiency and security in everything we build. As AI evolves faster than ever, we see a rare opportunity to lead — innovating on the tools and automation that raise both developer productivity and software quality. We work closely with our client teams — including Silk, Amazon WebView, Vega, and partner teams across Amazon — to understand what engineers need, then build solutions that delight them. We recognize that while building and testing a browser has its unique challenges, many other teams follow similar patterns, so we always look for opportunities to collaborate and scale with others in mind. We're committed to fostering an inclusive environment where diverse perspectives strengthen our work, and we invest in each other's growth through mentorship and knowledge sharing. We believe that striking the right balance between professional achievement and personal fulfillment leads to our best work and happiest team members.
