• Secure gateway abstraction using tools like LiteLLM, Portkey, or Kong

• Embedding and retrieval infrastructure using vector databases like Pinecone, or FAISS

• Audit, logging, and trace analysis with tools like LangSmith

• Guardrails integration for output validation, safety checks, and policy enforcement

• Develop multi-turn LLM agents and tools using LangGraph and LangChain to automate operational workflows

• Build robust APIs, SDKs, and accelerator components that serve as initializers for internal product teams, bots, and platforms to rapidly integrate and adopt GenAI services

• Standardize approaches to context management, tool calling, fallback handling, and observability across agents

• Ensure platform components meet security, governance, and compliance standards

• Partner with infrastructure, data, security, and product teams to integrate GenAI workflows into existing systems

Required Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or a related field.

• Proficient in Python; familiarity with LangChain, LangGraph, or similar LLM orchestration frameworks

• Familiarity with observability practices for LLM-based systems, including logging, latency tracking, and output monitoring

• Experience with LLM evaluation and testing frameworks to validate prompt behavior and agent reliability across iterations

• Strong understanding of cloud-native design patterns, secure AI API integration, and service scalability

• Working knowledge of vector databases such as Pinecone, FAISS, or Weaviate, along with retrieval-augmented generation (RAG) techniques

• Experience building modular, reusable GenAI components that support cross-functional adoption and internal accelerators

• Comfort working with CI/CD pipelines and collaborating with DevOps teams to deploy and monitor GenAI workflows

Preferred Qualifications:

• Masters Degree in a related field, and/or related certification/s
