Role SummaryWe are seeking a highly skilled Lead AI Developer with deep expertise in Generative AI (Gen AI), agentic AI applications, and RAG systems to join our AI innovation team. The successful candidate will design, develop, and deploy cutting-edge AI solutions for enterprise workflow automation and knowledge-driven applications that leverage custom internal data. The role involves hands-on development, system architecture, toolchain integration, and collaboration with cross-functional teams to bring AI-driven automation into production environments.Key Responsibilities
  • Architect and develop agentic AI systems that can plan, reason, and act using tools, APIs, and memory across various workflows
  • Build and optimize RAG pipelines using structured and unstructured enterprise data (documents, databases, APIs).
  • Integrate LLMs with external systems, tools, and APIs using frameworks like LangChain, LlamaIndex, or Semantic Kernel.
  • Design prompt engineering and function-calling strategies for dynamic and interactive agents.
  • Implement scalable and secure AI services that can be deployed in cloud environments (e.g., AWS, Azure, GCP).
  • Fine-tune or orchestrate use of open-source or commercial LLMs (e.g., GPT-4, Claude, Mistral, LLaMA) based on task-specific needs.
  • Collaborate with data engineers and MLOps to build robust data pipelines and monitoring frameworks.
  • Ensure AI systems are explainable, auditable, and aligned with organizational compliance and governance standards.
Stay current with the latest developments in agentic AI, orchestration frameworks, and foundation model APIs.RequirementsCore AI/ML & Gen AI Expertise
  • 5–8+ years of professional experience in AI/ML development; 2+ years in Gen AI and LLM-based solutions.
  • Strong understanding of transformer-based architectures and LLM capabilities.
  • Experience with RAG, embedding models, vector databases, and custom document indexing.
  • Experience building applications using OpenAI, Anthropic, Mistral, or open-source models (e.g., Ollama, Hugging Face).
Agentic AI Tools & FrameworksExperience with several of the following is strongly preferred:
  • LangChain/Langgraph
  • LlamaIndex
  • Semantic Kernel
  • Haystack
  • CrewAI / AutoGen / AutoGPT / OpenAgents / n8n
  • Transformers / Diffusers (Hugging Face)
  • OpenAI Function Calling / Tools API
  • ReAct / MRKL / Tree-of-Thought / AutoGPT-style frameworks
Application & Workflow Development
  • Proven experience building enterprise-grade AI applications, ideally in workflow automation, intelligent agents, or knowledge assistants.
  • Integration with APIs, tools, and external systems (e.g., CRMs, ERPs, proprietary internal platforms).
  • Experience with prompt engineering, tool use chaining, and multi-step agent orchestration.
Software Engineering & DevOps
  • Strong Python programming (must-have); TypeScript or JavaScript a plus.
  • Familiarity with containerization (Docker), orchestration (Kubernetes), and CI/CD pipelines.
  • Cloud deployment experience: AWS (SageMaker, Bedrock), Azure (OpenAI, ML Studio), or GCP.
Data & Infrastructure
  • Experience with vector databases like Pinecone, Weaviate, FAISS, Chroma, Qdrant.
  • Knowledge of data pipelines, ETL, and data engineering workflows.
  • Familiarity with data governance, security, and privacy requirements for enterprise systems.
Preferred Qualifications
  • Master’s or BS. in Computer Science, AI/ML, Data Science, or a related field.
  • Experience in multi-agent systems, AI planning, or autonomous AI agents.
  • Publications or contributions to open-source Gen AI frameworks a plus.
  • Experience mentoring junior developers and contributing to AI architecture decisions.
