WHY THIS ROLE IS IMPORTANT TO US

DMS Change Management provides reference data management and valuation solutions for many of the world's leading and most innovative financial institutions, including regional and global banks and asset management firms.

The Senior SDET (Software Development Engineer in Test) in the DMS Change Management Team is a strategic asset for our organization operating in this complex and demanding sector. Deep expertise in BDD-driven test automation using Gherkin and Cucumber on the C#.NET stack, combined with strong engineering discipline and leadership, is essential for ensuring the quality, reliability, and security of software applications that underpin the financial system.

By designing robust, maintainable automation frameworks and embedding quality early in the development cycle, the Senior SDET plays a crucial role in mitigating risks associated with software releases — translating into significant cost savings by avoiding rework and potential financial losses due to production errors.

Senior SDETs take on leadership roles within engineering and testing teams, guiding junior members, driving automation strategy and framework design, conducting code/test reviews, and mentoring others on BDD and automation best practices.

WHAT YOU WILL BE RESPONSIBLE FOR

Technical Expertise:

• Expert-level design and implementation of BDD frameworks using Gherkin and Cucumber (SpecFlow) on the C#.NET platform.

• Perform performance and security testing to ensure the system meets required standards.

• Analyze automation results and test metrics, identify trends, and recommend improvements to optimize testing processes and framework reliability.

Communication and Collaboration:

• Effectively communicate with stakeholders: developers, product owners, business analysts, etc.

• Collaborate with the development team to resolve defects and improve code quality.

• Participate in code reviews and provide testing/automation feedback.

• Present testing results, automation coverage, and findings in clear and concise reports.

Additional Responsibilities:

• Stay updated on industry trends: continuously learn and adapt to new technologies, tools, and BDD/automation best practices, including within the Capital Markets domain.

• Contribute to the testing community: share knowledge and expertise through presentations, internal training, or participation in industry forums.

• Take ownership of specific automation areas: become a subject matter expert for the BDD/Cucumber automation framework and drive its evolution.
