Mission Context
TCS is seeking a Senior API Test Automation Engineer to join the Mortgage Loans Squad within the Risk & Credits Tribe. This squad manages the acquisition platform for mortgages, leveraging a Java 8/Spring 5 backend with integrations to mainframe systems and external APIs. As part of an Agile team, you will play a critical role in ensuring the quality, reliability, and performance of API-driven solutions that support mortgage loan processing.
Your mission will be to manage tests from creating test plans, test cases in Octane, developing automated tests, conduct integration tests, support business acceptance tests. You will collaborate closely with developers, your product owner, and DevOps Teams to enhance test coverage, reduce manual testing efforts, and accelerate delivery while maintaining high standards of software quality.
Function Description
* Develop automates tests using Java, Rest-Assured, and Cucumber (BDD approach) to validate backend services for mortgage loan processing.
* Develop comprehensive test suites covering functional, regression, and contract testing for RESTful APIs, ensuring alignment with business requirements and technical specifications.
* Integrate the framework with CI/CD pipelines (e.g., Jenkins, GitHub Actions) to enable automated test execution in Agile sprints.
* Define and maintain test data strategies, including mocking external dependencies (e.g., mainframe APIs) to ensure isolated and reliable test execution.
* Analyze API responses for correctness, performance, and security, including validation of status codes, response payloads, headers, and error handling.
* Collaborate with developers to identify and troubleshoot defects, providing clear reproduction steps and logs for efficient resolution.
* Act as a quality advocate within the squad, promoting shift-left testing and test-driven development (TDD/BDD) practices.
* Participate in Agile ceremonies (refinement, planning, retrospectives) to contribute to testability improvements and risk mitigation strategies.
* Work with Product Owners to refine acceptance criteria and translate business rules into executable test scenarios (Gherkin).
* Monitor and report on test coverage metrics, defect trends, and automation efficiency to drive continuous improvement.
* Mentor junior team members on API testing best practices, tooling (e.g., Insomnia, Swagger), and automation techniques.
* Stay updated on emerging testing tools and methodologies and propose innovations to the squad.
Language Requirements
* Fluent in English (mandatory for documentation, collaboration, and stakeholder communication).
* You will stand out with Dutch or French (highly desirable for cross-team interactions within BNP Paribas Fortis).
Education
* Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
* Certifications in testing (e.g., ISTQB, Agile Testing) or API technologies (e.g., Rest-Assured, Insomnia) are a plus.
Agile Requirements
* Proven experience working in Scrum/Kanban teams with a strong Agile mindset.
* Familiarity with Agile testing quadrants and ability to adapt testing strategies to sprint goals.
* Experience with BDD (Behavior-Driven Development) using tools like Cucumber (in Java / Ruby)
* Ability to prioritize testing tasks based on business value and risk assessment.
* Required Experience & Knowledge
Technical Skills:
* 5+ years of experience in API test automation using Java, Rest-Assured, and Cucumber.
* Hands-on expertise with RESTful APIs, including request/response validation, authentication (e.g., OAuth2, Basic Auth), and error handling.
* Proficiency in Java 8+ and Spring Boot for backend testing and mocking.
* Experience with version control (Git) and CI/CD tools (Jenkins, GitHub Actions).
* Knowledge of Swagger/OpenAPI for API documentation and contract testing.
* Familiarity with databases (Oracle) and mainframe integrations (advantageous).
* Basic understanding of performance testing and security testing (OWASP principles).
* Testing Skills:
* Strong background in functional, regression, and integration testing for APIs.
* Ability to design test cases covering positive/negative scenarios, edge cases, and data-driven testing.
* Experience with mocking frameworks (e.g., Mockito, WireMock) to simulate dependencies.
Soft Skills & Attitude/Behavior
* Analytical mindset: Ability to break down complex systems into testable components.
* Collaborative, Transparent & Communicative : Works effectively with developers, DevOps, and business stakeholders.
