Job Description
SmartOSC is seeking a proactive and passionate Junior/Middle UI/UX Engineer
Designer to join our team. In this role, you will collaborate with internal teams and global stakeholders to design intuitive and engaging digital experiences within the airline sector.
Key Deliverables & Responsibilities
- Direct AI agents to draft test cases, test data, automated test scripts and bug reports from requirements and user stories.
- Review and approve what AI produces: catch missing scenarios (edge, negative), wrong expected results and false bug reports.
- Own the automated UI and API test suite in the CI pipeline (tests that run automatically on every code change); decide what to fix when it fails.
- Solve the problems AI cannot: find the root cause of failures across UI, API, data or AI prompt.
- Evaluate AI product answers for accuracy, consistency and hallucination (AI stating false information as fact).
- Build test datasets of questions + expected answers to check AI features release after release.
Requirements
1. Minimum 3.5 years working as a software QC / QA engineer, with hands-on test automation (not manual-only).
2. Builds and maintains automated UI and API tests (by hand or with AI agents) with Playwright, Selenium, Cypress or similar, in Python or TypeScript / JavaScript.
3. Defines test strategy and coverage for AI-driven testing: tells AI agents what to test (risks, edge cases, expected behaviour) and judges whether the AI-generated test set covers the real risks, not just the happy path.
4. Finds the root cause of a bug, not just the symptom (e.g. checks API response, data, logs before reporting).
5. Uses AI tools and coding agents (ChatGPT, Claude Code, Cursor, Copilot or similar) daily to produce test cases, scripts and bug reports, and reviews the output instead of trusting it.
6. Has basic AI knowledge: can understand in simple words what an LLM, a prompt and RAG (Retrieval-Augmented Generation: AI that answers from a company's own documents) are, and why AI output needs evaluation (e.g. hallucination, different answers to the same question).
7. Communication Skills: No English skill is required
Soft skills
1. Problem solving: breaks an unclear problem into small checks and narrows down the cause on their own before asking for help.
2. Critical thinking: questions requirements and AI output instead of accepting them; spots gaps or contradictions in a user story.
3. Learning agility: picks up new tools and concepts quickly, which matters because AI tools change every month.
Nice-to-have
Hands-on with LLM evaluation tools (DeepEval, Ragas, LLM-as-judge) or has built a chatbot / RAG project.
Growth path: AI Evaluation (Eval) Engineer
Within 3-6 months, you can grow into an AI Eval Engineer: the person who decides whether an AI feature is good enough to release.
