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, ensuring high-load test runs stay stable and understandable when issues occur. The role suits someone who enjoys working with distributed systems, improving tooling, and making test environments easier to operate and debug.
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.
