  • Hands-on solution engineering: designed complex AI solutions, built multi-stage pipelines, developed AI-driven systems (e.g. agentic workflows, RAG, synthetic data generation).
  • Comfortable with Python (NumPy, Pandas), API integration, and independently prototyping LLM-powered solutions.
  • Solid software engineering foundations: version control, testing, MVP thinking, iterative development.
  • Exceptional discovery and problem framing.
  • Seniority and track record: 8+ years delivering complex AI, ML, or data projects end to end.
