Company Description 👋🏼 We're Nagarro. We are a digital product engineering company that is scaling in a big way! We build products, services, and experiences that inspire, excite, and delight. We work at scale — across all devices and digital mediums, and our people exist everywhere in the world, with  18,000+ experts across 39 countries . Our work culture is dynamic and non-hierarchical, empowering our people to take ownership, collaborate openly, and create meaningful impact.

Job Description As a  QA Automation Engineer , your mission is to drive quality across complex, distributed systems by designing and implementing robust, scalable, and intelligent test automation solutions. You will focus on API testing, system integration, performance validation, and automated quality gates, helping engineering teams identify defects early and deliver reliable, high-quality products with confidence.

Design and implement scalable  test automation frameworks  covering API, integration, contract, regression, and architectural testing. Develop and execute comprehensive  API testing strategies  to validate functionality, integrations, data integrity, reliability, and system contracts. Build and maintain automated  quality gates within CI/CD pipelines , ensuring incorrect or non-compliant changes are identified and prevented from reaching production.

Validate  API and data contracts, backward compatibility, schema evolution, and architectural invariants  across distributed systems. Apply  property-based testing and mutation testing  to evaluate test effectiveness, identify gaps, and improve overall test coverage. Design and execute  performance and scalability testing , helping identify bottlenecks and potential reliability issues.

Collaborate with software engineers, architects, DevOps, and data engineering teams to establish and continuously improve quality engineering practices. Analyze automation failures, troubleshoot root causes, and continuously improve the reliability, maintainability, and scalability of the testing ecosystem. Qualifications 6+ years of experience  in software engineering, QA automation, data engineering, or software quality engineering.

Strong hands-on experience designing  test architectures and automation frameworks  for complex or distributed systems. Expert-level experience in API testing  and strong experience with API development and integration. Proven experience integrating automated testing and validation into  CI/CD pipelines  and implementing automated quality gates. Hands-on experience with  property-based testing and mutation testing , with an understanding of how they improve test effectiveness.

Experience validating  API/data contracts, backward compatibility, schema evolution, and architectural invariants . Practical experience with  performance testing , scalability validation, and identifying application or system bottlenecks. Strong analytical, troubleshooting, communication, and collaboration skills, with the ability to work effectively across engineering, architecture, QA, and DevOps teams.
