Software Engineer 5 - Payments Experience Automation Infrastructure

Netflix•Los Gatos, CA

About The Position

At Netflix, we aim to entertain the world. To do that, our Commerce Engineering team must ensure that every payment experience—from a new member signing up in Brazil to an existing member updating their payment information in Japan—is seamless, secure, and bulletproof. We are looking for a visionary Automation Engineer to own the end-to-end testing strategy and infrastructure for our global payment and checkout experiences. This isn't just about writing scripts; it’s about architecting an AI-first testing ecosystem that empowers developers to ship code with total confidence. You will not just manage a test suite; you will architect an autonomous, AI-driven quality platform. You will leverage 10+ years of engineering expertise to bridge complex backend microservices with global checkout experiences, building 'invisible' infrastructure that uses GenAI to predict failures before they happen.

Requirements

Deep understanding of the Test Pyramid and know exactly when to use a unit test versus an integrated E2E flow.
Deep experience with modern web automation tools like Playwright or Selenium, alongside API and contract testing frameworks.
Understand how to correlate data across distributed backend systems and microservices.
Pathologically curious. Find the "edge cases of the edge cases" that others miss.
10+ years of engineering expertise.
Strong ownership mindset, treating the reliability of our payment systems as a "tier 0" priority.
Own the test strategy and build tools that make it easy for other developers to write and maintain high-quality tests.
Experience navigating the nuances of global payments, including local regulations, diverse currencies, and regional checkout behaviors.
Take full ownership and effectively drive success in your assigned areas. You will be responsible for setting the standards.

Nice To Haves

Java, Javascript, Python, GraphQL, Github Actions, Selenium WebDriver, Playwright, Jest, Cucumber, Mocha.

Responsibilities

Define and execute the E2E testing strategy for payment management and checkout flows, ensuring support for hundreds of global payment methods.
Architect and build Generative AI-powered tools to automate scenario generation, intelligently detect regressions, and provide smart test guardrails.
Develop software solutions that generate high-quality, high-cardinality synthetic test data to simulate complex global payment permutations.
Design tools to automatically detect, quarantine, and reproduce flaky tests. Take responsibility for weekly deployment sign-offs.
Integrate test coverage data with runtime traces and code changes to provide a 360-degree view of system health and reliability.
Identify gaps in the existing suite of integration, visual screenshot, API, mock, contract, and performance tests. Work with the team to prioritize and close gaps.
Facilitate seamless end-to-end testing and integration for all other engineering teams leveraging the payments platform.
Partner with cross-functional teams to foster a "reliability-first" culture, documenting frameworks and troubleshooting guides that elevate the entire engineering org.
Closely collaborate with engineers within the team and with partner teams to identify needs and influence the direction of testing infrastructure. Partner with product and engineering to define test strategies for new features.
