Job summary

Miratech is seeking a Senior QA Automation Engineer to drive quality across a cloud-native WFM/CX platform. You will own test automation across unit, component, integration, contract, API, end-to-end, and performance tests, focusing on microservices and cloud-native applications.

Collaboration with engineers, architects, and product teams is essential to raise quality standards and design scalable automation frameworks.

Qualifications

• 6+ years of QA Automation experience.
• Prove­n experience designing component and integration test suites for Java microservices (e.g., Spring Boot Test, Testcontainers, WireMock, REST Assured);
• Strong hands-on experience with Playwright and/or Cypress using TypeScript or JavaScript.
• Experience with contract testing (e.g., Pact, Spring Cloud Contract).
• Experience with performance and load testing tools and practices (e.g., JMeter, Gatling, k6).
• Experience testing REST APIs, microservices, and distributed systems.
• Experience testing WFM forecasting and scheduling engines or other complex rule-based business systems, e.g., validating forecast outputs against historical volume and handle-time data, staffing calculations against service-level targets, and generated schedules against labor rules, shift patterns, breaks, and skills.
• Experience integrating automated testing into CI/CD pipelines and quality gates.
• Strong analytical and troubleshooting skills.

Responsibilities

• Design, develop, and maintain automated test frameworks using Playwright and/or Cypress, JUnit, and modern test automation practices.
• Build and execute automated test suites at every level: unit (JUnit), component, integration, contract, API, end-to-end, and regression.
• Own component and integration testing of microservices, validating service behavior, data flows, and API contracts both in isolation and across service boundaries (e.g., using Testcontainers, WireMock, or Pact).
• Design and run performance and load tests to validate scalability, throughput, and response times under peak contact-center volumes.
• Design and automate test scenarios for Workforce Management functionality, including forecasting, schedule generation, and scheduling rules and constraints.
• Integrate automated tests into CI/CD pipelines and quality gates.
• Collaborate with developers, architects, product managers, and business stakeholders to define acceptance criteria and quality standards.
• Analyze defects, identify root causes, and drive quality improvements across the SDLC.
• Establish quality engineering standards, reusable automation assets, and test strategies across multiple product streams.
