Nice To Haves

Strong understanding of SDLC/STLC, defect lifecycle, and test strategy (risk-based testing, shift-left, quality gates)
Hands-on experience testing UI and APIs (REST/JSON), including integration and end-to-end testing across services
Experience with test automation using at least one modern language/toolset (e.g., Java, JavaScript/TypeScript, Python, C#) and frameworks (e.g., Playwright/Cypress/Selenium, REST Assured/Postman)
Familiarity with CI/CD pipelines (e.g., GitHub Actions, Jenkins, Azure DevOps) and integrating automated tests into pipelines
Ability to analyze logs, troubleshoot issues, and partner with engineers on root-cause analysis
Strong communication skills and ability to document test plans, quality status, and release readiness
Experience testing microservices and distributed systems (contract testing, service virtualization, event-driven flows
Exposure to data validation (SQL, ETL testing, data quality checks) and test data management
Knowledge of performance testing (e.g., JMeter, k6) and basic security testing concepts (OWASP)
Cloud and container experience (AWS/Azure/GCP, Docker, Kubernetes)
Experience with observability tools (Splunk, Datadog, New Relic, Grafana) to support monitoring and testability
Experience validating AI-enabled features (model behavior checks, prompt/response evaluation, bias/quality metrics, regression testing for LLM changes)
Domain experience in payments, financial services, or regulated environments

Responsibilities

Own end-to-end test strategy across UI, API, services, data, and AI-enabled features
Define quality gates (entry/exit criteria) and drive risk-based test planning for complex, multi-service releases
Lead shift-left practices by partnering early with product/engineering to embed testability into architecture and design
Design, build, and maintain automated test suites (unit, integration, API, UI, contract, regression) integrated into CI/CD pipelines
Create and manage test data, environments, mocks/stubs, and service virtualization to enable reliable testing
Execute exploratory testing on high-risk areas and validate non-functional requirements (performance, security, reliability, accessibility)
Monitor and improve quality metrics (defect leakage, coverage, flakiness, escape rates) and drive continuous improvement actions
Triage defects, perform root-cause analysis with engineering, and verify fixes through regression and targeted automation
Ensure release readiness by coordinating test execution, validating cross-service integrations, and reporting quality status to stakeholders
Champion best practices for coding standards, testability, observability, and “quality ownership” across the team
