What You Will Do

Work in a cross-functional agile team and be responsible for designing, developing, and evolving systems that validate and improve the performance, scalability, and reliability of backend services running on AWS Design and implement performance and reliability strategies for our core backend systems, including defining service-level expectations (latency, throughput, error rates) and validating them under realistic conditions Build frameworks and tooling to simulate real-world production scenarios, including multi-service interactions, high concurrency, and network variability Develop and maintain load, stress, and endurance testing systems, integrated into CI/CD pipelines to detect regressions before production Analyze system behavior using metrics, logs, and distributed tracing , identifying bottlenecks and driving improvements across services Define and drive the adoption of a comprehensive testing strategy across backend services , including unit tests, integration tests (leveraging test containers), and clear guidelines for when and how each layer should be applied

Enable a shift-left quality culture by building tooling, patterns, and best practices that allow teams to detect regressions early Collaborate with feature teams to improve system design, resilience, and scalability, acting as a force multiplier across backend engineering Leverage AI tools and agentic workflows in your daily work — from tech planning, code generation and review to exploring novel solutions.
