You will work closely with developers, QA, product, and DevOps teams throughout the development lifecycle.Key Responsibilities:Quality Ownership: Own end-to-end quality for assigned backend features — define the test strategy, expand coverage with AI tooling, and keep validation continuous through the development lifecycle. Partner with engineering and product on requirements and release readiness.Risk Detection: Analyze requirements, service behavior, and production signals to surface edge cases, coverage gaps, missing telemetry, flaky tests, and configuration drift early.Backend Test Automation: Build and maintain API, integration, and end-to-end tests in Java or a comparable language. Use AI coding assistants and test agents to accelerate development, widen coverage, and reduce maintenance.Infrastructure and CI/CD: Deploy and validate backend services in Docker and Kubernetes.

Verify business rules, API contracts, and data consistency across environments.Distributed Systems and Performance: Validate microservices, event-driven workflows, message queues, and asynchronous pipelines, including retries, duplicate events, and failure recovery. Use SQL and AI-assisted analysis to detect data anomalies, and run load tests to assess latency, throughput, and scalability.Production Troubleshooting: Independently investigate production issues using logs, metrics, traces, and tools such as Bits AI.

Validate findings, communicate release risk clearly, and promote effective AI-assisted quality practices across engineering teams.Qualifications:Strong proficiency in Java or a similar programming language, with hands-on software development experience building test frameworks, automation services, AI tooling, or developer productivity solutions. Practical experience applying LLMs or AI coding tools to testing and development workflows — generating tests, analyzing failures, or supporting defect triage — with the ability to review and validate their outputs.
