• 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
• Experience working in Agile/Scrum teams
• Upper-Intermediate English or higher - you'll be communicating directly with the client and cross-functional team members
• Familiarity with Palantir Foundry is a strong plus

We offer*:
