Technical Overview:


We're seeking a highly skilled AI Application Engineer to lead the architecture and execution of advanced LLM-driven systems, including prompt engineering pipelines, evaluation frameworks, RAG workflows, and LangChain-based orchestration.

  • This role demands a blend of deep prompt engineering expertise, practical Python development skills, and a strong analytical mindset to optimize prompt performance and user experience in real-world systems.
Required Expertise:
  • 3 - 6 years in AI/ML, NLP or GenAI roles.
  • Advanced knowledge of prompt engineering strategies and heuristics.
  • Proficient with LangChain (or similar), Python and API development.
  • Solid experience building RAG pipelines with vector DBs.
  • Strong analytical mindset with an A/B testing and evaluation-driven approach.
