Senior Software Development Engineer in Test (Java, Selenium)

The SDET role specializes in development of capabilities and code to automate testing of the product or system under test. You will be part of a business-aligned development squad that specializes in building, enhancing and maintaining custom software and solutions supporting the business. In this role, you will design, build, and own engineering-grade test automation frameworks that ensure the quality, reliability, and scalability of mission-critical systems. You will partner closely with software engineers, architects, product managers, and platform teams to embed quality throughout the SDLC, influence technical direction, and support the transition from legacy platforms to scalable, resilient, cloud-ready architectures. This is a hands-on, code-driven role requiring strong Core Java programming skills and deep Selenium automation expertise. You will actively develop automation frameworks, write reusable Java components, and solve complex testing and system-stability challenges across UI, API, and backend layers. This is not a manual QA or scripting-only position-it is a technical leadership role focused on building scalable automation solutions and driving engineering excellence at enterprise scale. Your Primary Responsibilities:

• Design, build, and maintain scalable Java-based automation frameworks using Selenium WebDriver, TestNG, and/or JUnit.
• Develop clean, reusable Java code (utilities, base classes, helpers) by applying object-oriented programming principles such as inheritance, polymorphism, and encapsulation.
• Implement automation design patterns such as Page Object Model (POM) to ensure maintainability and extensibility.
• Develop automated tests for UI, REST APIs, and backend systems, including database validation using JDBC/JPA and SQL.
• Actively debug, refactor, and optimize Selenium tests, including locator strategy, waits/synchronization, and flaky test remediation.
• Integrate automated test suites into CI/CD pipelines using tools such as Jenkins and Bitbucket to enable continuous testing.
• Participate in code reviews, design discussions, and hands-on technical problem-solving related to automation architecture and quality strategy.
• Collaborate with developers, product owners, and DevOps teams within Agile environments to drive continuous improvement in quality and delivery., Serves as a dedicated technology resource for advancing DTCC’s business opportunities and providing industry thought leadership for leveraging new technology. The goal of this new department is to partner internally with IT, our business and regulatory divisions and externally with clients, regulators, and fintech vendors, to help build new platforms and business models to advance DTCC’s mission to support the financial markets.
