You’ll work closely with integration platforms (middleware/iPaaS), third-party systems, and a combination of automated and manual testing strategies. As a senior member of the QA team, your input will shape processes, influence engineering best practices, and help deliver reliable, scalable solutions.

What You Will Do:

• Conduct user acceptance, exploratory, regression, and end-to-end testing.
• Develop automated functional and performance tests from scratch.
• Perform manual testing of new features and bug fixes.
• Identify, triage, and troubleshoot issues across distributed systems (e.g., microservices, event-driven architectures).
• Own end-to-end testing of integrated proprietary and third-party services.
• Recommend design changes to increase testability.
• Collaborate with stakeholders to assess severity, prioritize, and track issue resolution.
• Guide engineering teams on testing best practices and coordinate coverage across unit, integration, and contract testing.
• Define and execute performance testing (load, stress, etc.).
• Prepare and maintain QA documentation (test plans, test cases, test metrics, issue logs).
• Reconcile data across key systems to ensure consistency.

Who You Are:

• 3–5+ years of experience in a senior QA or software testing role.
• Strong experience designing and executing test strategies and plans.
• Proficiency in TypeScript is a must.
• Proven experience in building automation frameworks and solutions from scratch.
• Expertise with RESTful API testing frameworks and tools.
• Strong understanding of CI/CD test execution (preferably YAML-based pipelines).
• Experience defining and conducting performance tests (load, stress).
• Knowledge of middleware/iPaaS platforms is a plus.
• Passion for improving deployment, security, stability, and overall software quality.
• Ability to collaborate effectively with cross-functional teams (developers, product managers, designers).
• Strong problem-solving and communication skills.
