This role

As a Software Development Engineer in Test, you will play a crucial role in the development and maintenance of automated testing frameworks, tools, and scripts for our financial services software applications. You will collaborate closely with cross-functional teams, including developers, product managers, and other SDETs, to drive the delivery of high-quality software solutions. Your expertise in test automation will be instrumental in ensuring the reliability, performance, and security of our products, as well as identifying and resolving issues throughout the software development life cycle.

Responsibilities

  • Design, develop, and maintain automated test frameworks and scripts for UI, API, and integration testing across web and mobile platforms.

  • Conduct various types of testing, including functional, integration, regression, and performance testing.

  • Contribute to the evolution of our existing test automation framework by developing new utility functions and improving reporting capabilities

  • Collaborate with the development team to identify test requirements, design and execute test plans, and create comprehensive test cases.

  • Proactively identify and report software defects, troubleshoot issues, and work closely with developers to ensure timely resolution.

  • Generate clear and concise test reports, document test results, and maintain accurate test documentation.

  • Collaborate with cross-functional teams (product, security, operations) to ensure the overall quality and security. 

  • Stay up-to-date with the latest industry tools, trends, and best practices in automation testing and software quality assurance

Requirements

  • Strong foundation in test automation principles, including test architecture design, framework selection, and scalable test suite organization.

  • Familiarity with Agile testing methodologies and test-driven development (TDD).

  • Excellent problem-solving and debugging skills.

  • Strong communication and collaboration skills to work effectively in a team.

  • Attention to detail and a commitment to delivering high-quality results.

  • 5+ years of experience in software engineering, quality engineering, test automation, or a related role.

  • Specific tool experience is less important than the ability to evaluate and adopt the right tool for the context. Familiarity with tools such as Playwright, Cypress, or Selenium is a plus, not a prerequisite.

  • Ability to write clear, concise, and comprehensive test cases and documentation.

  • Bachelor's degree or higher in Computer Science, Engineering, or a related field, or equivalent work experience.

Nice to have

  • Experience in fintech, payments, or fraud prevention
  • Familiarity with mobile testing frameworks
  • Experience testing across multi-region or internationally distributed systems
  • Exposure to performance or load testing tools
