You will work closely with our QA leadership, engineering teams, and product stakeholders to ensure robust end-to-end, API, regression, and performance test coverage. This role is hands-on and technical: you build test frameworks, write automation code, execute performance testing, and drive continuous improvement in our testing infrastructure. You bring both coding expertise and deep domain knowledge of banking workflows, enabling you to write tests that catch not just broken builds, but actual business logic issues.

• Build and maintain comprehensive regression test suites for Finxact user experience, artificial intelligence, and related services, catching broken functionality and business logic regressions
• Design and execute performance and load testing strategies to validate system behavior under stress, using tools like JMeter, Gatling, or similar, and reporting on performance bottlenecks
• Develop automated testing scripts for user workflows across the platform, leveraging your understanding of software development and core banking workflows to write meaningful tests
• Collaborate with engineering teams to troubleshoot automation failures, debug inconsistent tests, and drive root cause analysis toward systemic improvements
• Maintain and evolve test data strategies and fixtures to support comprehensive test coverage across multiple software development and core banking scenarios
• Participate in agile ceremonies and contribute to continuous improvement of our testing processes
• Share testing best practices and patterns with the development team, contributing to a quality-first culture

• Bachelor's degree in Computer Science, Engineering, Information Technology, or equivalent combination of education and professional experience
• 3+ years of professional software development experience with hands-on test automation and SDET responsibilities
• 2+ years of experience building end-to-end test automation for modern web applications (Cypress, Playwright, Selenium) with demonstrated proficiency in JavaScript or TypeScript
• 2+ years of experience with API/integration testing, RESTful services, and tools like Postman or similar
• Strong programming skills with the ability to write clean, maintainable test code
• Experience with CI/CD pipelines, Docker, and modern DevOps tooling
• Demonstrated experience with test frameworks and testing best practices
• Experience with performance or load testing
• Excellent written and verbal communication skills to collaborate with technical and non-technical stakeholders
• Attention to detail with the ability to think critically about edge cases and failure modes
• Self-motivated team player comfortable in a fast-paced, agile environment

• 3+ years of experience in banking or financial services, with understanding of core banking workflows (payments, accounts, lending, compliance)
• Hands-on experience with Cypress framework
• Experience with JavaScript, React, and/or Go development
• Hands-on experience with performance testing tools (JMeter, Gatling, or similar)
• Familiarity with GitLab, Jira, and Confluence
