We're hiring a senior Software Engineer in Test to lead how Netflix tests the experiences members use on their TVs and phones. You'll define what quality means for complex, fast-moving features, build the tools and automation that prove it, and help every engineer around you ship with confidence. The Teams Live UI The Discovery and Viewing Experience (DVX) Live team owns the UI engineering and architecture that powers Live viewing experiences across TV, iOS, and Android. Members show up for live events once, with no second airing and no patch mid-show, so every feature we build is a promise that it will work at that moment on every device that tunes in. As our senior SDET, you'll lead the way we test Live: recreating the moments a live event creates, like a vote opening just as an ad ends, long before the event does, so we know we're ready instead of finding out during the show. What we're working on: • The FIFA Women's World Cup, coming to Netflix in 2027 and 2031, will feature new experiences built for global, multi-match sport tournaments. • Interactive and navigational features that help members move through a live event and catch the moments that matter. • Real-time voting, which lets members influence a live show as it unfolds, alongside millions of others watching at the same moment. Mobile Core The DVX Mobile Core team develops and advances the architecture of Netflix's Android member app. We leverage systems and infrastructure widely available at Netflix and determine the best way to adopt and apply them on Android, enabling easier, more efficient patterns for downstream product engineering teams. What we're working on: • Modernizing our app architecture for the iOS and Android member app. This involves driving migrations and a cross-platform Player rewrite, creating leverage for product teams to ship faster and more reliably on iOS and Android. • Driving Quality of Experience (QoE). Owning monitoring and performance improvements across Player UI and canvases, as we scale. The Role Problem you'll help solve: • Testing and making sure millions of members see our Live-specific UI features and capabilities at the right moment, on every TV and phone. • Giving every platform the same test plan, so TV, iOS, and Android are consistently validated the same way. • Making tests reliable enough that PMs, designers, engineers, and our partners trust them, and fast enough to run on every change. • Keeping quality steady while the iOS and Android apps modernize, including a cross-platform player rewrite, so faster delivery doesn't come with more regressions. What you'll do: • Lead testing for complex features across platforms. Agree on one test plan per feature that teams can trust and validate together, and implement it on TV, iOS, and Android, rather than reconciling differences afterward. • Build automation that people trust. Evolve our test systems and CI integration across platforms so tests are fast and reliable. • Make tricky live moments easy to test. Build ways to recreate them on demand instead of waiting for a real event, using mocks, overrides, real devices, and test data that looks like a real event and doesn't expire. • Make large migrations safe. Build the test strategy that lets the iOS and Android apps modernize without regressions reaching members • Own quality metrics. Track how well we're covered, how reliable our tests are, and which bugs reach members, and use that to decide what to improve next. That includes the client metrics that reveal problems only scale shows, and the alerts that tell us about them quickly. • Make sure bugs only surprise us once. When a bug reaches members, make sure it comes back as a test, using agents to turn each finding into several, and document how to test each feature so the knowledge doesn't live in one person's head. • Build and leverage AI tools. Act as a force multiplier to flag unwanted behaviors before they reach members, and apply agents to test authoring, failure triage, and bug analysis. • Shape testability from the first commit. Partner with engineers on architecture and code that are easy to test, and help them write better tests themselves. • Test where teams meet. Agree with partner teams on the contracts between our features and theirs, so end-to-end tests verify where teams meet and rehearse what members experience, rather than retesting every team's systems. • Collaborate beyond the team. Work with partner teams on shared test data, environments, and tools, and with teams that run live events to ensure features are ready before showtime and can be safely switched off if needed. • Mentor and grow others, including engineers and SDETs, by reviewing test plans and test code, sharing practices, and making quality everyone's job. What we're looking for: • 8+ years of professional experience in software testing and test automation, with a strong record of leading testing for large, cross-team features or projects. • Comfort working across platforms. You've tested consumer apps on more than one platform, and you're eager to learn the platforms you haven't used yet. • Strong coding skills, with experience designing and building test frameworks and tools, not just writing test cases. • Experience or strong interest in using AI for testing, such as writing tests, triaging failures, or finding gaps in coverage, with clear ways to check its results. • Deep experience integrating automated tests into CI/CD pipelines and diagnosing flaky tests, infrastructure failures, and dependency issues. • Experience with mocking, test data, or other ways to make hard-to-reproduce situations repeatable in tests. • A practical, risk-based approach to quality: knowing where to invest in tests, which risks are acceptable, and when more testing isn't the answer. • Excellent communication and collaboration skills, including explaining quality risks and trade-offs to engineers, product managers, and partners in terms they can act on. • Alignment with Netflix's culture and values. Nice-to-haves: • Experience with live streaming, video playback, ads, or other systems where split-second timing matters. • Hands-on experience with testing frameworks on several platforms, such as Jest, Puppeteer, Espresso, or XCUITest. • Experience driving shared testing infrastructure or quality strategies adopted by multiple teams. • Experience testing how systems behave when things go wrong, such as chaos testing or failure drills. Growth opportunities: We're hiring a senior engineer, and we see this role growing into one that sets the standard for how Netflix tests its Live experiences and mobile apps at scale. Over time, you can: • Lead testing strategy across teams, creating the practices and tools that other teams adopt. • Shape client architecture for testability across platforms. • Influence partner teams' tooling and roadmaps, so our experiences are easy to test for everyone. • Mentor and grow engineers and SDETs across the organization.
