Software Development Engineer in Test (SDET) – Java.
About The Position
The Software Development Engineer in Test (SDET) is part of a business-aligned development squad responsible for building, enhancing, and maintaining high-quality software solutions. The position combines software development and test engineering, emphasizing Core Java programming, technical problem-solving, and test automation development. The SDET designs and develops scalable automated testing solutions across UI, API, and backend systems, applying software engineering principles to improve software quality, reliability, and testability. The role requires hands-on Java programming to independently write, debug, and maintain code and create robust, scalable, and maintainable test automation solutions. The SDET works with developers, product owners, and engineering teams across the software development lifecycle and participates in Agile ceremonies, code reviews, and continuous improvement initiatives. DTCC’s Information Technology group delivers secure, reliable technology solutions supporting the global capital markets. The company offers a flexible/hybrid work model of three days onsite and two days remote; the onsite days are Tuesdays, Wednesdays, and a third day determined by the team or employee.

- Develop API automation and validate RESTful services using Rest Assured or similar technologies.
- Perform backend and database validation using SQL, JDBC, and relational databases.
- Debug application and automation code to identify defects, test failures, and root causes.
- Develop and optimize complex SQL queries for data validation and backend testing.
- Integrate automated tests into CI/CD pipelines using technologies such as Jenkins, CloudBees, Bitbucket, and Git.
- Contribute to integration, API, functional, regression, smoke, and end-to-end automated testing, and partner with developers to strengthen unit-test coverage.
- Apply Test-Driven Development (TDD) and Behavior-Driven Development (BDD) practices where appropriate.
- Collaborate with software developers, product owners, and engineering teams throughout the software development lifecycle.
- Participate in Agile ceremonies, code reviews, and continuous improvement initiatives.
Benefits
- Competitive compensation, including base pay and annual incentive.
- Comprehensive health and life insurance and well-being benefits, based on location.
