Responsibilities
•Design, implement, and maintain automated tests for native iOS and Android apps (Kotlin/Kaspresso, Swift/XCUITest, or comparable stacks), following Page Object Model and stable test architecture.
•Wire automated mobile suites into pipelines (build triggers, artifacts, flaky-test hygiene, reporting), and keep tests reliable for release trains.
•Plan and execute test design for new features and releases — smoke, regression, and targeted exploratory testing when risks are high.
•Test client–server contracts, edge cases, and integrations; validate APIs and backend behavior that power the mobile experience.
•Work with analytics, monitoring, and logging (e.g., Amplitude, Sentry, Kibana) to reproduce issues, assess impact, and improve observability for QA.
•Triage defects independently, narrow reproduction steps, assess severity, and communicate clearly to engineering and product.
•Apply domain judgment for wallets, payments, and asset flows; flag risks that affect user funds, compliance, or privacy.
•Use LLMs and Copilot-style tools pragmatically for test ideas, documentation, analysis, and routine automation work — without compromising rigor.
•Partner with developers, product, and other QA engineers on requirements, testability, and release readiness in an Agile environment.
Requirements
•4+ years of experience in mobile application testing automation (iOS and Android).
•Solid experience writing automated tests for native mobile apps using Kotlin/Kaspresso (Android) and/or Swift/XCUITest (iOS).
•Strong understanding of mobile automation architecture, Page Object Model, and test design patterns.
•Experience integrating automated tests into CI/CD pipelines.
•Experience in API and backend testing and solid understanding of client-server interaction.
•Knowledge of testing methodologies (black-box, white-box, regression, smoke, exploratory).
•Experience testing fintech products — payment apps, crypto wallets, banking apps, or similar.
•Proficiency with analytics, monitoring, and logging tools (e.g., Amplitude, Sentry, Kibana).
•Product mindset — user happiness and software quality are genuine priorities, not formalities.
•Strong ability to triage issues independently and communicate findings clearly.
•Familiarity with blockchain, crypto wallets, or Web3 products.
•Hands-on experience integrating AI tools into day-to-day QA workflows (e.g., LLM-assisted test generation, AI-powered test analysis, Copilot-style tooling).
•Fluent Russian and Intermediate (B1) or higher proficiency in English.
Nice to have
•Experience with AI-based visual testing or anomaly detection in mobile UIs.
•Contributions to open-source testing frameworks or automation tooling.
•Experience with performance or security testing of mobile applications.
Conditions
•Stability, development, participation in the future unicorn's growth.
•Remote work from anywhere in the world, excluding Russia and Belarus, with a schedule aligned with GMT+3.
•Competitive salary in EURO/USDT.
•20 working days of paid vacation.
•Birthday presents.
•Compensation for the purchase of necessary technical devices for the work.
•Paid sick leaves.
