4 TO 6 YEARS OF EXPERIENCE

Salary Range: Based on the experience

Architect and Implement AI Solutions

• Design and build RAG pipelines using Azure AI/Search and vector databases: chunking, embeddings, hybrid/semantic ranking, re-ranking, evaluation, and citation display.
• Build enterprise conversational systems (multi-turn, retrieval-grounded) with prompt lifecycle management, guardrails, audit logging, and telemetry.
• Support multiple LLMs and modalities: Azure OpenAI, Llama (Meta), Claude, etc.., and task-specific OSS models (vision, speech), with policy‑driven model routing for performance, safety, and cost.

Integrate and Operate AI Infrastructure

• Implement Model Context Protocol (MCP) servers integrating with project related areas.
• Provide tool functions with RBAC scopes, schema versioning, rate limiting, request/response validation, and audit trails.
• Deploy Azure AI Agent Service (AGA) patterns for agent registry/broker/governance with agent telemetry and policy enforcement.
• Use Azure Batch for large‑scale, parallel inferencing/vectorization jobs; leverage AWS EMR for distributed data/feature processing in AI pipelines.

Develop and Manage Data Pipelines

• Build ingestion and enrichment for RAG connectors and ETL/ELT: document normalization, PII redaction, metadata enrichment, SLA/SLO monitoring, and lineage.
• Operate large‑scale vectorization with quality gates and drift monitoring.
• Use Azure Data Factory (ADF) and Azure Databricks for orchestrated, scalable data processing; use AWS EMR for Hadoop/Spark workloads supporting AI features.

Build Agentic AI Solutions

• Design secure tool‑calling and multi‑agent orchestration using Semantic Kernel, AutoGen, Microsoft Agent Framework, CrewAI, Agno, and LangChain or others.
• Know how to apply agent governance and MCP‑based controls across heterogeneous agents and runtimes (register, observe, govern, retire).

Model Evaluation and Optimization

• Evaluate and fine‑tune open‑source and proprietary models; optimize for quality, latency, safety, and cost with A/B and offline eval suites.
• Implement CI/CD with automated tests, security scans. Have knowledge on how to secure model workloads.
