Role Description At Exerizon, quality isn't an afterthought — it's built into every stage of delivery. We're looking for a Junior Tester to join our team and help make sure the systems and data platforms we build for customers meet a high bar. - Work side by side with developers, business analysts, and architects across SAT and UAT cycles. - Write precise test cases. - Help bring modern, AI-assisted practices into day-to-day testing. - Grow in a technically demanding, fast-moving environment. Qualifications - 2–4 years of hands-on experience in SAT and UAT testing. - A clear grasp of the test pyramid concept and familiarity with test automation principles. - Preferably, experience with AI tools that support the SDLC. - Working knowledge of ISTQB fundamentals (certification is a plus). - Ability to write clear, accurate, and thorough test cases. - Basic SQL and test automation skills. - Experience working with technical and business documentation. - Polish and English in professional capacity. Requirements - 100% remote work — collaborate from anywhere. - B2B contract with a competitive rate [80–110 PLN/h + VAT]. - Flexible working hours. - Modern tech stack with AI-assisted tooling in the SDLC. - Real ownership and direct impact on the quality of what we ship. - A supportive, low-bureaucracy team that values clear communication.

Role Description When a Roamless user lands in Tokyo and their eSIM activates in seconds that's because dozens of things went right across our app, our backend, and a global patchwork of carrier systems. When one of them doesn't, it's this team's job to find out why. We're hiring a Network & Mobile Senior QA Engineer to join a small, high-ownership QA team at a company where quality directly affects whether a traveller stays connected in a foreign country. The role is responsible for mobile app testing (iOS + Android) and core network and eSIM testing. What makes this role genuinely different from most QA jobs: - A significant part of what you test involves third-party carrier systems that can behave unexpectedly. - When something breaks in that layer, you need to trace it through logs, API responses, and system behaviour. - Strong analytical thinking is the core of this job. What you will do… - Test the Roamless iOS and Android apps across real devices and device farms: functional, regression, and smoke testing across every weekly release. - Test core eSIM and network behaviour: eSIM activations, data routing, carrier fallback, and edge cases that emerge from international network scenarios. - Execute and expand integration test coverage across app-to-backend flows. - Debug failures that cross system boundaries: trace root causes through backend logs and API responses, not just surface-level symptoms. - Maintain and extend test documentation in Jira/X-ray. - Integrate AI tooling into your QA workflow (automated ticket creation, MCP-based agents, testing automation). - Work directly with engineers to surface quality issues early in the release cycle, not just at the end. Qualifications - Strong experience testing mobile applications (iOS and/or Android). - Backend and API testing experience: comfortable using Postman, reading API responses, validating payloads across service boundaries. - Integration testing experience: you've tested flows that cross multiple service or system boundaries. - Ability to read code and understand system logic: you don't need to write production code, but you must be able to trace a failure through backend behaviour and logs. - Strong analytical thinking: especially when debugging third-party systems where failure modes are unpredictable. - High ownership and autonomy: This is a small team and we expect everyone to own their area, not wait for direction. - Strong English and Turkish communication skills. Requirements - Experience with Appium or Robot Framework for mobile test automation (nice-to-have). - SQL or basic querying skills (nice-to-have). - Background in telecoms, eSIM, network testing, or carrier integrations (nice-to-have). - Familiarity with automation scripting for mobile testing (nice-to-have). Benefits - Hardware you need to be most productive. - Location: Fully-remote anywhere in Turkey. - Home office budget: $500 on equipment for home office setup (eg. a keyboard, a screen, etc). This is a one-off budget that doesn’t renew every year, but doesn’t expire. - Learning and development budget: Up to $1000 annually to be spent on books, online courses, conferences, etc. - $200 non-expiry yearly Flex credit for data, hotspot, and calls. - Annual phone number subscription for $1/year: A real phone number (UK, Canada, or Australia) inside the Roamless app. - Full-time local contract. - Supportive, diverse, inclusive team.
