ABOUT THE ROLE We are looking for a Manual QA Engineer to ensure the quality and reliability of web applications and AI-driven features in an Agile environment. This role is critical in validating user experiences, APIs, and LLM-powered functionality, safeguarding accuracy, compliance, and performance across releases. You’ll collaborate closely with engineering to strengthen testing practices, contribute to CI/CD quality gates, and elevate standards in both traditional and AI-focused QA processes.

WHAT YOU WILL DO

  • Perform manual testing of web applications to identify bugs, glitches, and inconsistencies;

  • Develop, maintain, and execute detailed manual test cases based on product requirements and specifications;

  • Perform thorough cross-browser UI testing to ensure consistent behavior across Chrome, Firefox, Safari, Edge, etc.;

  • Validate AI-generated test cases, summaries, and recommendations produced by integrated LLMs to ensure accuracy, completeness, and alignment with project requirements;

  • Design and execute test scenarios to verify AI behavior, including prompt–response consistency, contextual relevance, and deterministic vs. non-deterministic outputs;

  • Evaluate AI model quality using defined acceptance metrics (precision, recall, hallucination rate, duplication rate);

  • Conduct manual API testing to validate request/response accuracy, error handling, and integration;

  • Use TestRail to create, manage, and track test plans, test cases, and test execution results;

  • Use Jenkins CI/CD pipelines;

  • Report and document defects clearly using the bug tracking system (JIRA);

  • Participate in daily stand-ups, sprint planning, and other Agile team meetings;

  • Review user stories and acceptance criteria to understand the scope of testing;

  • Estimate own tasks, report on risks to the team lead;

  • Collaborate with developers and other QA team members to reproduce issues and verify fixes;

  • Maintain and update test documentation as needed.

MUST HAVES

  • 2+ years of experience with manual testing;

  • Basic understanding of methodologies and SDLC and STLC (Software Development and Testing Life Cycle) models;

  • Knowledge of Testing and Quality Assurance Processes;

  • Strong experience with Test Design activities to cover a set of product requirements;

  • Knowledge of Test Design techniques;

  • Knowledge of testing methodologies;

  • Defect analysis skills and the ability to write detailed and useful defect reports with expected defect-fixing outcomes;

  • Experience with Postman (API testing) and Browser developer tools;

  • Experience with UI testing;

  • Understanding of LLM evaluation principles, including prompt engineering, output validation, and model fine-tuning cycles;

  • Familiarity with AI/ML concepts, APIs, and frameworks (e.g., OpenAI API, Azure OpenAI, LangChain);

  • Knowledge of data protection and compliance standards for AI systems (GDPR, zero-data retention, PII anonymization);

  • Experience with TestRail as a Test Management system (as a user, test execution is required);

  • Basic understanding of CI/CD process;

  • Upper-intermediate English level.

NICE TO HAVES

  • Experience with SSO testing;

  • Experience in Performance or Load.
