Job Summary :

We are seeking a hands-on Senior AI Engineer (5-7 years experience) to design and build enterprise-grade Agentic AI applications within the AWS ecosystem.

The ideal candidate has strong Python development experience, practical exposure to Large Language Models (LLMs), and hands-on experience building Retrieval-Augmented Generation (RAG) and multi-agent workflows using frameworks such as LangChain/LangGraph or similar.

This role focuses on designing, integrating, deploying, and operating AI-powered services on AWS, ensuring scalability, security, reliability, and cost efficiency.

Key Responsibilities :

- Design and implement Agentic AI workflows using LLMs (OpenAI, Bedrock, or equivalent).

- Develop Python-based backend services for : Model orchestration, Tool/function calling, Context management, API exposure.

- Build Retrieval-Augmented Generation (RAG) pipelines using vector databases (e.g., Pinecone, FAISS, OpenSearch).

- Design secure and scalable AI APIs using AWS services such as Lambda and API Gateway.

- Deploy and manage AI workloads using AWS Bedrock and SageMaker.

- Implement CI/CD pipelines and Infrastructure as Code (CloudFormation/CDK/Serverless Framework).

- Apply MLOps best practices including : Model versioning, Prompt versioning, Monitoring and observability, Logging and performance tracking.

- Ensure AI systems are : Reliable and resilient, Secure (IAM, policies, encryption), Cost-aware and optimized.

- Practical experience building : RAG systems, Multi-agent or agentic workflows, Tool-calling or function-calling architectures.

- Experience with frameworks such as : LangChain / LangGraph (or equivalent orchestration frameworks).

- Solid experience with AWS services : Bedrock, SageMaker (model hosting/inference; full training expertise not mandatory), Lambda, ECS, S3, API Gateway, IAM etc.

- Experience deploying applications using Infrastructure as Code (CloudFormation, CDK, Serverless Framework).

- Understanding of : Prompt engineering, LLM limitations and guardrails, Context window management, Token optimization.

- Familiarity with vector databases and embedding workflows.

- Strong debugging, problem-solving, and system design skills.

Preferred Qualifications :

- Experience designing secure enterprise AI solutions.

- Exposure to SAP AI, enterprise ERP integration, or business process automation.
