General Responsibilities
Communicate clearly and proactively with teammates, product, and stakeholders — raising risks, blockers, unclear requirements, and quality concerns early
Work closely with cross-functional teams including frontend, backend, and DevOps to validate features end-to-end across environments and ensure release readiness
Create, maintain, and execute test scenarios for new features, regressions, edge cases, and bug fixes, with clear documentation of coverage and results
Identify, document, and track defects with clear reproduction steps, expected vs actual behaviour, supporting evidence, and business impact
Participate actively in requirement reviews and team discussions — challenging ambiguous logic, spotting missing cases, and helping prevent issues before implementation reaches QA
Troubleshoot and investigate issues across development, staging, and production environments, contributing to root cause analysis and overall quality improvement
Technical Requirements
Must Have:
5+ years of professional QA experience, with at least 3 years in manual and API testing within production environments
Strong understanding of software QA fundamentals — test planning, test case design, regression testing, exploratory testing, and defect lifecycle management
Hands-on experience testing web applications, admin panels, and complex business flows in production-like environments
Strong practical experience with API testing tools such as Postman, Swagger, or similar — request validation, authentication flows, response structure verification, and error scenario coverage
Ability to validate backend/frontend integration through API and UI testing, with clear understanding of request/response behaviour and data consistency across systems
Experience writing clear, structured, and traceable test cases, test scenarios, and bug reports with enough detail for developers to reproduce issues efficiently
Experience testing real-time systems or asynchronous flows — WebSockets, Server-Sent Events, queues, delayed jobs, notifications, or event-driven behaviour
Understanding of microservices-based systems — cross-service flows, integration points, failure scenarios, and end-to-end validation across distributed components
Practical experience with browser debugging tools, network inspection, and log analysis for identifying issues across frontend and backend layers
Strong understanding of HTTP — methods, headers, status codes, authentication, sessions, cookies, and common integration issues
Experience with test management and defect tracking tools such as Jira, TestRail, Zephyr, or similar
Ability to execute structured regression testing before releases and clearly communicate release risk, test coverage, and open issues
Strong communication and ownership mindset — able to challenge unclear requirements, identify edge cases early, and proactively prevent defects rather than only report them
Advantage to have
Experience with automated testing tools or frameworks such as Playwright, Selenium, or similar
Experience with performance and load testing tools such as JMeter, k6, or Gatling
Familiarity with Kafka or other event streaming systems from a QA perspective — validating producers/consumers, message flow, retries, and delivery expectations
Experience testing caching mechanisms, background jobs, cron-based workflows, and distributed systems behaviour
Fintech, or any high-availability transactional domain
Understanding of security-focused testing concepts — authentication, authorisation, input validation, XSS, CSRF, and common web vulnerabilities
Experience validating analytics, reporting, exports, dashboards, and large dataset behaviour in backoffice systems
Experience with zero-downtime releases, production smoke testing, and post-release verification practices
This role will report to head of Happines department and will be based onsite in our Cyprus, Limassol office.
