State Street’s Wealth Custody & Clearing (WC&C) business delivers institutional grade custody, clearing, and platform services to wealth managers, broker dealers, and financial institutions. As WC&C modernizes and scales its digital platforms, quality engineering and automated testing are critical to ensuring platform reliability, data integrity, and regulatory grade controls.

We are seeking a Software Development Engineer in Test (SDET) to serve as a hands-on quality engineering contributor, embedded within Wealth Technology delivery teams and accountable for building robust automated testing solutions across frontend, backend, and integration layers.

Role Summary

This role is a senior individual contributor position focused on test automation, quality engineering, and software validation in a regulated, production critical environment.

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

• Partner closely with application developers, product managers, and platform engineers to embed quality early in the SDLC

• 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

• Exposure to wealth management, brokerage, or financial services systems is strongly preferred

• 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

Education

• Bachelor’s degree in Computer Science, Engineering, or a related field

• Equivalent practical experience will be considered

Why State Street

• Support mission critical wealth platforms used across global custody and clearing markets

• Operate as a true quality engineer—writing test code, not managing people

• Partner with experienced engineers and architects on complex, high impact systems

• Competitive compensation, benefits, and a strong technical IC career path
