Job description

About the Role

We are seeking a Python Developer with strong backend engineering expertise and hands-on exposure to Generative AI, Machine Learning, and Deep Learning to design, build, and scale AI-driven applications.

The role involves developing production-grade AI solutions leveraging Large Language Models (LLMs), deep learning models, and cloud AI services across cloud or on-premises environments.

You will be responsible for building high-performance backend services, integrating advanced AI/ML models, and enabling scalable API-driven platforms.

The ideal candidate should have experience in building LLM-powered systems, implementing Agentic AI workflows, and applying AI-first approaches to solve business problems.

You will work closely with cross-functional teams to deliver reliable, scalable, and secure AI solutions integrated into enterprise systems.

Key Responsibilities

• Design, develop, and integrate LLM-based solutions (e.g., OpenAI GPT, LLaMA, HuggingFace models) into enterprise products and workflows
• Implement Retrieval-Augmented Generation (RAG), prompt engineering, embeddings, chunking strategies, and fine-tuning for business use cases
• Develop APIs and integration layers to seamlessly connect AI models with frontend and backend systems
• Build and maintain scalable backend applications using Python with microservices architecture
• Design and implement RESTful APIs using frameworks such as FastAPI (mandatory), Flask, or Django
• Develop Agentic AI workflows including multi-agent coordination, tool/function calling, memory handling, and workflow orchestration
• Integrate AI models into applications using APIs and ensure secure and efficient communication across systems
• Collaborate effectively with frontend (Flutter) and backend (Node.js/Python) teams for smooth AI feature deployment
• Test, debug, and manage API integrations using tools like cURL and other debugging mechanisms
• Build and deploy AI services on cloud platforms using AWS services such as Lambda, S3, API Gateway, EC2, ECS/EKS, DynamoDB, and RDS
• Leverage Amazon Bedrock and SageMaker for model deployment, orchestration, and scaling
• Develop and integrate machine learning and deep learning models using frameworks such as TensorFlow, PyTorch, and scikit-learn
• Work on NLP, classification, regression, clustering, anomaly detection, and time-series modeling problems
• Build scalable data pipelines for data processing, training, validation, and inference
• Ensure systems are secure, scalable, cost-optimized, and production-ready with proper monitoring and observability
• Implement DevOps and MLOps best practices including CI/CD, model versioning, logging, and performance tracking
• Collaborate with product teams and stakeholders to translate business requirements into AI-driven solutions
• Contribute to architecture design, innovation, and continuous improvement of AI platforms

Required Technical Skills:

LLM & AI Integration (Mandatory – Hands-on)

• Strong hands-on experience working with LLMs and Generative AI systems
• Experience integrating LLMs such as OpenAI GPT, LLaMA, HuggingFace models into real-world applications
• Experience with frameworks such as LangChain, LlamaIndex, LangGraph, ADK, or similar
• Hands-on experience with vector databases such as Pinecone, Weaviate, Milvus, FAISS, or OpenSearch
• Proven ability to build and deploy RAG pipelines, embeddings-based retrieval systems, and prompt engineering workflows
• Experience integrating AI models via APIs into live production systems

Programming & Frameworks

• Strong proficiency in Python for backend development, data processing, and AI/ML integration
• Experience with FastAPI (mandatory), Flask, or Django for API development
