As AI transforms the future of financial services, we're building the platforms that help regulated organizations adopt AI responsibly and at scale.

What is the Opportunity?

The QA Engineer III will be responsible for leading and executing functional quality assurance activities for complex banking and financial applications. The role requires strong hands-on manual testing expertise, practical automation experience, thorough test documentation skills, and solid database validation capabilities. The engineer will own end-to-end test coverage across backend processes, integrations, APIs, file-based workflows, and data validations, while working closely with developers, business analysts, product teams, and other QA engineers to ensure release quality.

What will you do?

• Own functional, regression, integration, system, and end-to-end testing for complex applications and backend workflows.
• Analyze business and technical requirements, identify test scenarios, assess test coverage, and highlight requirements or design gaps early in the delivery lifecycle.
• Create and maintain high-quality test documentation including test plans, detailed test scenarios, test cases, traceability matrices, test evidence, execution reports, and release-quality summaries.
• Perform database and backend validation using SQL to verify data integrity, transformations, transactional accuracy, and downstream processing results.
• Validate APIs and service integrations using tools such as Postman and support automation of repeatable API and backend regression scenarios.
• Develop, maintain, and execute automated tests using appropriate UI, API, or backend automation frameworks; contribute to improving regression efficiency and coverage.
• Perform defect analysis and triage, provide clear reproduction details and supporting evidence, and collaborate with engineering teams through resolution and retesting.
• Validate file-based workflows, scheduled jobs, and inter-system data exchanges, including reconciliation of source and target results.
• Estimate testing effort, plan test execution, identify delivery risks, and communicate testing status and quality concerns to project and QA leads.
• Mentor less experienced QA engineers on functional testing practices, test design, documentation quality, defect reporting, and effective validation techniques.
• Contribute to QA process improvements, reusable test assets, automation candidates, and continuous improvement initiatives across the team.

What do I need to succeed?

Must Have:

• 8+ years of software QA experience , with strong hands-on functional/manual testing expertise and meaningful experience with test automation.
• Hands-on experience testing batch processing systems , including scheduled jobs, batch files, job dependencies, restart/recovery scenarios, and batch reconciliation.
• Experience with event-driven and data-intensive systems , including exposure to Kafka message flows, topics and payload validation, as well as ETL testing, data pipelines, source-to-target validation, transformation rules, and data reconciliation.
• Strong automation experience using tools and frameworks such as Selenium, Cypress, Playwright, Rest Assured, Java, Python, or equivalent technologies.
• Experience with modern delivery environments , including CI/CD pipelines, Git, Jenkins, GitLab CI, Azure DevOps, and exposure to cloud-native or microservices architectures, Azure, and Kubernetes.
• Exposure to AI-assisted QA , including GenAI testing tools, AI-based test design or automation, or practical use of AI to improve testing efficiency and coverage.
• Banking or financial services experience , with a solid understanding of the complexities and quality requirements of enterprise applications.
• Bachelor's degree in computer science, Information Technology, Engineering, or related discipline.
• Proven ability to independently own testing for complex releases or functional areas , identify gaps and risks, and ensure quality throughout the delivery lifecycle.
• Strong analytical, problem-solving, and troubleshooting skills, with exceptional attention to detail and the ability to challenge assumptions constructively.
