Responsibilities
* Build Agentic Workflows: Implement orchestration, retrieval pipelines, and validator agents using graph-aware tools.
* Optimize Retrieval: Build hybrid search pipelines (lexical + vector) and integrate vector databases like FAISS, Milvus, or Pinecone.
* Model Integration: Integrate LLMs (Azure OpenAI, Anthropic) and support domain-specific fine-tuning or adapter models.
* Scalable Engineering: Develop robust API endpoints and ETL pipelines to support model and agent runtimes.
* Experiment & Evaluate: Create evaluation suites for reliability, drift detection, and performance optimization.
Requirements
* Python Expertise: 3+ years of strong Python engineering experience.
* Graph Intelligence and Databases: Working knowledge of knowledge graph modeling (schemas, ontologies, entity resolution) and graph databases. Hands-on experience with Neo4j, Memgraph, AWS Neptune, ArangoDB, or similar. Familiarity with graph embeddings and GNNs (GCN/GAT) is a plus.
* Evaluation & Experimentation: Comfortable designing experiments, building eval harnesses, and reasoning about model quality, robustness, and bias in production AI systems.
* Modern AI Patterns: Hands-on experience building RAG pipelines and agentic workflows. Comfort with prompt engineering and tool/function calling. Experience building text-to-SQL or semantic parsing capabilities over structured data sources.
* LLM Observability: Familiarity with LLM evaluation frameworks (e.g., Ragas, DeepEval, Langfuse) and production monitoring of AI systems.
* Retrieval & Search: Lexical + vector + hybrid retrieval, embeddings, and reranking. Experience incorporating user and context signals for personalization.
* Fine-tuning & Adaptation: Experience with fine-tuning and adaptation patterns (e.g., LoRA/QLoRA, instruction tuning, embedding model fine-tuning).
* APIs & Integrations: Solid knowledge of APIs, microservices, and data-centric integrations.
* Engineering Discipline: Solid software engineering fundamentals - clean code, testing, debugging, code reviews, and comfort working in agile pods.
* Cloud & Deployment: Experience with AWS/Azure/GCP and CI/CD workflows.
* Excellent problem-solving skills and keen attention to detail.
* Ability to participate in the discussions and lead the technical discussions
* Have a consultancy mindset → always try to find a solution for the client
