Key Responsibilities

• Analyze requirements and mockups before development starts and define acceptance criteria

• Test calculations and financial scenarios
• Test all types of tasks: features, automation, tech debt, and bug fixes
• Run smoke and regression testing before release and after deployment, and keep regression suites up to date
• Handle user reports: reproduce issues, create development tasks, track their status, and give feedback to the requester
• Log and prioritize defects in Jira and verify fixes
• Prepare and maintain test data and test users
• Maintain the knowledge base: feature descriptions, risk areas, typical incidents, and how to reproduce them
• Take part in team syncs
• Later on, contribute to e2e test automation with Playwright together with the development team

Requirements

• 2+ years of manual testing experience with web applications
• Fluent Russian (C2/native)
• English sufficient for reading technical documentation (B2/C1)
• Experience in adjacent domains is preferred, primarily digital advertising and adtech / fintech / payments / billing / marketplaces
• Solid test design skills: equivalence classes, boundary values, decision tables, and state transition diagrams
• Ability to write checklists and test cases from requirements and mockups, including when documentation is incomplete
• REST API testing experience: Swagger/OpenAPI, Postman, and cross-checking API responses against the UI
• Proficiency with Chrome DevTools (Network, Console): analyzing requests and responses and pinpointing whether a defect is on the frontend or backend
• SQL skills: SELECT, JOIN, GROUP BY, and data verification at the database level
• Ability to write complete bug reports: steps to reproduce, expected vs. actual result, environment, logs or a HAR file, severity, and priority
• Ability to work through requirements independently in a small team without a dedicated analyst, and to clarify them during backlog grooming
• Basic understanding of Git and CI/CD: branches, merge requests, pipelines, and test environments
• Experience working with AI tools: using LLMs to generate checklists, test data, and SQL queries and to analyze logs, while critically validating the results
• Following data-handling rules: financial information, personal data, and tokens are never shared with public LLMs

Nice to Have
