  • Support teams in developing retrieval-based approaches that make internal knowledge accessible to AI use cases.
  • Evaluate tools, platforms, and approaches with an eye to scalability, security, and maintainability.
  • Help teams choose appropriate solutions based on context rather than applying AI by default.
  • Optimize AI system efficiency through principled model selection based on cost-performance trade-offs, inference latency, and token usage.
  • Support the implementation of safeguards such as access controls, validation, and monitoring, collaborating with Security, Legal, and other stakeholders.

  • Solid understanding of APIs, system integration, and distributed systems.
  • Practical experience working with AI tools or platforms (e.g., LLM APIs or similar technologies).
  • Familiarity with prompt design, context engineering, retrieval-based approaches, or AI-driven workflows.
