Job Description

As a Senior 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.
