Binance offerings range from trading and finance to education, research, payments, institutional services, Web3 features, and more. We leverage the power of digital assets and blockchain to build an inclusive financial ecosystem to advance the freedom of money and improve financial access for people around the world.
About the Role
We are looking for a Senior Site Reliability Engineer (SRE) with solid Node.js experience to help maintain and improve our internal testing and validation systems. You will work on the reliability and performance of our distributed test environment, which supports web, API, and Android testing.
A key part of the role is to build and refine our internal monitoring and alerting, making sure our high-load, real-time test runs stay stable and easy to understand when issues occur. This includes improving how we track failures, measure system health, and respond to problems across the different components of the test stack.
If you enjoy working with distributed systems, improving tooling, and making test environments easier to operate and debug, this role will suit you well.

Responsibilities


  • Maintain, operate, and improve distributed test execution systems across web, API, and Android platforms.
  • Ensure the reliability, performance, and scalability of test environments including Selenium grids, Appium setups, VPN containers, and supporting microservices.
  • Expand testing capabilities by enabling new jurisdictions, product flows, and environment configurations.
  • Develop and refine internal tooling, diagnostics, and automation to reduce operational overhead and improve system visibility.
  • Troubleshoot complex issues across distributed systems, containers, networked services, mobile emulators, and API integrations.
  • Support environment provisioning, CI/CD integration, and orchestration of test execution pipelines.

Requirements


  • 5+ years of professional experience with Node.js, ideally in SRE, DevOps, test automation, or platform engineering.
  • Strong understanding of software engineering fundamentals and testing methodologies.
  • Hands-on experience with modern testing frameworks such as Playwright, Puppeteer, or WebDriver/WDIO.
  • Experience with Android development or mobile automation (Appium, emulators, ADB, debugging).
  • Strong analytical and troubleshooting skills across distributed and containerized systems.
  • Ability to design, maintain, and debug reliable test environments across local, staging, and production-like setups.

Bonus Skills


  • Experience with Docker and Kubernetes for orchestrating multi-service test stacks.
  • Experience with time-series databases such as ClickHouse for metrics, analytics, or results storage.
  • Familiarity with observability tooling (Prometheus, Grafana, OpenTelemetry).
  • Background in CI/CD pipelines, cluster deployments, or environment automation.
  • Understanding of VPN routing, network debugging, and environment-dependent test scenarios.
