What You Will Do (Core Responsibilities)

• E2E Test Strategy & Design: Architect and own the end-to-end test strategy for complex payment flows, from authorization and tokenization to clearing and settlement. Define quality gates, risk-based testing approaches, and success criteria for large-scale programs.
• Integration & API Test Automation: Design, build, and maintain scalable automated test suites for REST/gRPC APIs, message queues (e.g., Kafka), and third-party partner integrations. Implement and champion contract testing and service virtualization to enable independent testing.
• Framework Architecture & Enhancement: Lead the evolution of our test automation frameworks. Promote and enforce best practices for creating maintainable, scalable, and efficient test code. Mentor other engineers on framework usage and contributions.
• CI/CD Pipeline Integration: Engineer and integrate comprehensive test suites into our CI/CD pipelines (Jenkins, GitLab CI) to provide rapid feedback to development teams and ensure release readiness.
• Advanced Failure Analysis & Triage: Drive the investigation of complex, multi-system failures. Perform root cause analysis and collaborate with cross-functional teams to implement preventative measures.
• Quality Governance & Mentorship: Mentor SDETs and QA engineers on test design and automation best practices. Define and report on key quality metrics (e.g., defect leakage, test reliability, release risk) to stakeholders and leadership.
• Test Data & Environment Management: Design and implement robust strategies for managing test data and ensuring the stability and availability of complex, integrated test environments.

Core Practices

• Distributed Systems Testing: Proven experience testing in a microservices architecture, including service-to-service communication, data consistency, and resiliency.
• Agile Methodologies: Extensive experience working as a quality leader within Agile/Scrum teams.
• Technical Leadership: Demonstrated ability to mentor engineers, influence architectural decisions for testability, and lead quality initiatives across multiple teams.
• Problem Solving: Exceptional analytical and debugging skills, with a talent for solving complex, cross-system issues.

Nice-to-Have Skills

• Payments Domain Knowledge: Experience in the payments or fintech industry, with an understanding of transaction lifecycles, ISO 8583 messaging, or related standards.
• Performance Testing: Experience with performance and load testing tools like JMeter or Gatling.
• Containerization & Cloud: A solid understanding of Docker, Kubernetes, and cloud platforms (AWS, GCP, Azure).
• Observability: Familiarity with using logs, metrics, and traces (e.g., Splunk, Grafana, Prometheus) to diagnose and validate system behavior.
