N-iX is looking for a Tech Lead QA Engineer with AI experience to join our team. We’re building an AI-powered document analysis platform from the ground up, combining a CMS backend, modern UI, and a RAG-based AI layer.
Обов’язки
- Follow a phased QA approach — begin with CMS and backend testing to establish a reliable baseline, then apply those insights to validate AI agent outputs effectively
- Design and execute test cases for REST APIs, covering functional correctness, edge cases, error handling, authentication, and data integrity
- Perform UI testing across core user journeys, validating layout, behavior, and integration with backend services
- Transition into AI output validation once the deterministic layers are stable — using business rules to identify inconsistencies, hallucinations, or degraded outputs
- Document and maintain test cases, test plans, and bug reports in a structured and traceable way
- Participate in requirement reviews and technical discussions to identify testability gaps early
- Collaborate with the Lead Big Data/AI Engineer and AI team to understand RAG pipeline behavior, document ingestion flows, and output quality expectations
- Contribute to building reusable test assets and QA processes as the project scales
Вимоги
- 4+ years of experience in manual QA, with exposure to frontend, backend and AI testing
- Solid experience with API testing using tools such as Postman, REST Client, or similar
- Experience testing web UIs and understanding of cross-browser/cross-environment considerations
- Ability to read and interpret API documentation, data schemas, and system architecture descriptions
- Hands-on experience working on projects that included AI, ML, or NLP components — particularly validating outputs that are probabilistic or context-dependent
- Familiarity with the concept of RAG (Retrieval-Augmented Generation) or LLM-based systems
- Strong analytical thinking — especially the ability to assess whether an AI response is contextually correct, not just technically non-null
- Good understanding of test documentation practices: test plans, test cases, bug reports, traceability
- English level at least Upper-Intermediate
Що пропонуємо
- Flexible working format – remote, office-based or flexible
- A competitive salary and good compensation package
- Personalized career growth
- Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
- Active tech communities with regular knowledge sharing
- Education reimbursement
- Memorable anniversary presents
- Corporate events and team buildings
- Other location-specific benefits
