• Coordinating directly with product managers and application users globally (with particular focus on adoption)
• Mentoring and developing more junior team members on all matters above

Candidate’s profile:

• Technically strong:
  • Has professional experience across data science and data engineering (shipping production grade analytics/AI applications)
  • Hands‑on experience building LLM applications (e.g., prompt design, retrieval‑augmented generation, embeddings, vector stores, evaluation & guardrails, cost/performance tuning) and willingness to engineer the full stack to get them into production
  • Familiarity with agentic patterns (tool use, planning, function calling, document workflows) and LLM orchestration frameworks
  • Solid statistical foundations (e.g. regression, time series, uncertainty estimation)
  • Any Dataframe API (like Spark or Pandas) and SQL
  • Query optimizations (RDBMS or Spark) and indexing
  • Strong Python (production‑grade). Java and/or Scala are a plus; functional programming experience is a plus
  • Knowledge of scripting languages, such as Python, R, bash
  • Experience working on all stages of the software development lifecycle
