• Experience with enterprise AI frameworks (LangChain, LlamaIndex, CrewAI, Haystack, or similar) 
• Strong programming skills in Python and experience with modern AI/ML tooling (PyTorch, TensorFlow, etc.) 
• Experience designing RESTful APIs, microservices architectures, and event-driven systems 
• Track record of shipping production AI systems at scale in enterprise environments 
• Strong communication skills with the ability to translate complex technical concepts for diverse audiences 
• Bachelor's degree in computer science, Engineering, or related field (Master's or PhD preferred) 

Preferred Qualifications

• Knowledge of Model Context Protocol (MCP) and agent communication standards 
• Experience with vector databases, RAG architectures, and semantic search systems 
• Familiarity with cloud platforms (AWS, Azure, GCP) and their AI services 
• Experience in SaaS or enterprise software companies 

What Makes This Role Exciting

• Shape the future of AI-powered business planning at a leading enterprise platform 
• Work on cutting-edge agentic AI systems that autonomously reason about complex business problems
