Solid working experience with Python for AI service development, API integration, and data processing.
Practical hands-on experience with LangChain, RAG pipelines, or similar developer frameworks.
Familiarity with LLM integration, prompt design, and embedding-based retrieval.
Experience deploying applications on AWS (preferred) or GCP, particularly with EKS, ECS, or Cloud Run.
Proficiency with Docker, Kubernetes, and cloud-native service orchestration.
Experience building RESTful or GraphQL APIs for AI and data services.
Understanding of cloud security, scalability, and performance optimization principles.
Good-to-Have:
Experience developing conversational UIs, copilots, or AI-enabled dashboards (e.g., Slack apps, chat widgets).
Familiarity with React, Next.js, or TypeScript for front-end feature integration.
Exposure to Hugging Face Transformers, LlamaIndex, or LangGraph ecosystems.
Knowledge of vector databases and data pipeline management.
Understanding of compliance, privacy, and responsible AI practices in enterprise environments.
Education & Experience:
Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
Typically 4–8 years of experience in software or AI engineering, including 2+ years of hands-on experience with LLMs, LangChain, or RAG systems.
Responsibilities
AI Solution Development: Build and maintain production-grade AI systems using LLMs, LangChain, and RAG pipelines to solve enterprise-scale problems.
Model Integration: Implement, fine-tune, and evaluate LLMs using frameworks such as LangChain, LlamaIndex, Hugging Face, or OpenAI API.
Backend & API Engineering: Develop scalable Python microservices and APIs for inference and knowledge retrieval.
Deploy and operate services on AWS (preferred) or GCP using EKS, ECS, or Cloud Run.
Implement observability, monitoring, and autoscaling for production workloads.
Retrieval-Augmented Generation (RAG): Design and optimize retrieval workflows using vector databases like FAISS, Pinecone, or Milvus.
Integrate both structured and unstructured data into LLM pipelines for grounded responses.
Front-End Integration: Collaborate with UI teams to integrate AI experiences into dashboards or chat UIs using React, Next.js, or TypeScript.
Ensure seamless communication between front-end components and AI APIs.
Cloud & DevOps: Containerize and deploy using Docker and Kubernetes.
Implement CI/CD pipelines with tools like Jenkins, GitHub Actions, or Terraform.
Cross-Functional Collaboration: Work closely with product, data science, and platform teams to deliver robust, secure, and impactful AI services.
