Overview

We are seeking a Senior Software Development Engineer in Test (SDET) to support integration testing for a high-visibility financial services system. This role involves developing manual and automated test suites, integrating them into the CI/CD pipeline, and collaborating with cross-functional teams to ensure the delivery of reliable, scalable, and efficient software solutions.


Key Responsibilities

  • Define comprehensive automation strategies tailored to project needs and establish success metrics.
  • Develop and maintain automated test suites using Selenium, Java, and C#. Write scalable, maintainable scripts to validate functionality, performance, and security. Conduct API testing with tools like Rest Assured.
  • Integrate automated tests into CI/CD pipelines using tools such as Azure DevOps, Jira, GitHub, or others. Apply version control, build automation, and test orchestration best practices.
  • Execute performance tests to assess system scalability and stability under load, analyzing metrics to recommend optimization strategies.
  • Assist with manual testing within sprints to meet project deadlines.

  • Proven experience in test automation, particularly with Selenium, Java, and C#.
  • Strong analytical skills with experience troubleshooting complex issues.
  • Familiarity with CI/CD concepts and tools such as Azure DevOps, Jira, or GitHub.
  • Experience with API testing and performance testing.
  • Experience with "N-1 process automation testing" (automation testing lags development by one sprint).
  • High proficiency in verbal and written communication.
  • Strong organizational and time management skills.


Preferred Skills

  • Experience with Appium for UI and mobile testing.
  • Familiarity with financial services systems and industry protocols/regulations.
  • Leadership experience in defining QA programs, plans, and approaches.
  • Proactive and assertive problem-solving skills.
