You will design, build, and maintain automated testing frameworks, partner closely with developers and product teams, and act as a quality advocate throughout the software development lifecycle. This position emphasizes engineering driven testing, not manual execution, or people management. 

Core Responsibilities 

• Design, develop, and maintain automated test frameworks for frontend, backend, and API driven systems 

• Build and execute automated test suites covering functional, regression, integration, and end-to-end scenarios

• Validate system behavior across wealth custody, clearing, trading, and servicing workflows 

• Create and maintain test data strategies that support repeatable, reliable automated testing 

• Identify, document, and track defects while contributing to root cause analysis and defect prevention 

• Ensure applications meet enterprise expectations for accuracy, reliability, resiliency, and regulatory compliance 

• Support production readiness efforts, including release validation and post deployment issue analysis 

Required Experience 

• 7+ years of experience in software quality engineering, SDET, or test automation roles 

• Strong experience working as a hands-on individual contributor embedded within engineering teams 

• Proven ability to design and implement automated testing solutions for complex systems 

• Experience working in enterprise or regulated environments where quality and control are critical 

• Strong collaboration skills and the ability to influence quality outcomes without formal authority 

Domain Exposure – Wealth & Financial Services

• Familiarity with validating workflows such as:  

• Account and portfolio lifecycle events 

• Trading and order management processes 

• Operational servicing and exception handling 

• Understanding of testing needs related to role-based entitlements, data accuracy, auditability, and controls 

• Experience supporting systems subject to regulatory oversight (e.g., SEC, FINRA) is a plus 

Technical Skills 

• Strong proficiency in test automation tools and frameworks (e.g., Selenium, Cypress, Playwright, or equivalent) 

• Experience testing API based and microservices architectures, including integration and contract testing 

• Familiarity with Java, JavaScript, or other backend/frontend languages used for test development 

• Experience working with CI/CD pipelines to integrate automated testing into deployment workflows 

• Knowledge of performance, resiliency, and negative path testing concepts 

• Strong understanding of testing best practices, quality metrics, and defect management
