Job Summary

The incumbent is responsible for designing, building, integrating, and operationalizing enterprise artificial intelligence (AI) solutions that support CN’s next generation of data, analytics, automation, and agentic capabilities. The role requires strong full-stack software engineering skills to translate business opportunities into production-grade AI applications, autonomous AI agents, intelligent workflows, and platform-integrated services. The incumbent works end-to-end—across frontend/backend development, data engineering, machine learning, and generative AI—to deliver secure, governed, reliable, and scalable AI solutions. A critical aspect of this role is taking ownership of the deployment lifecycle, utilizing CI/CD pipelines and DevOps/LLMOps best practices to move AI use cases from concept to production on CN-approved platforms.

AI Engineering, Full-Stack Development, and Solution Delivery

·       Design, develop, test, and deploy end-to-end full-stack AI-powered applications, autonomous AI agents, and intelligent workflows that address business needs and deliver measurable value.

·       Build and enhance generative AI, machine learning, and automation solutions using CN-approved engineering patterns, platforms, and controls.

·       Architect and implement agentic workflows, Retrieval Augmented Generation (RAG), prompt engineering, and model evaluation patterns to support scalable production solutions.

·       Develop reusable application programming interfaces (APIs), robust backend services, and interactive frontend components that accelerate AI delivery and promote consistency across use cases.

 Data Integration, CI/CD, and Deployment

·       Lead the deployment of AI solutions into production environments, establishing and maintaining robust CI/CD pipelines for automated testing, integration, and delivery.

·       Integrate AI solutions with enterprise applications, data platforms, business processes, and operational workflows.

·       Develop and optimize data pipelines, services, and interfaces that support reliable, secure, and scalable AI applications.

·       Contribute to enterprise AI platforms, including Databricks, Gemini Enterprise, Vertex AI, and related technologies, applying LLMOps best practices to support solution delivery.

Governance, Operations and Continuous Improvement

·       Apply AI governance, security, privacy, Responsible AI, and model risk controls throughout the solution lifecycle.

·       Support production deployment, monitoring, troubleshooting, quality evaluation, red-teaming, hallucination mitigation, and continuous improvement of AI solutions.

·       Document technical designs, decisions, limitations, and operational requirements to support maintainability, auditability, and successful handover. 

Requirements

Experience

AI & Full-Stack Engineering

·       Over 2+ years of experience in full-stack development, AI engineering, data science, or related technology delivery roles with a strong focus on production deployments.

·       Over 1 year of proven hands-on experience building and deploying enterprise copilots, chatbots, workflow assistants, autonomous AI agents, or agentic applications to production.

·       Strong experience with CI/CD pipelines, DevOps/LLMOps practices, and deploying containerized applications into cloud environments.

·       Experience with generative AI, large language models (LLMs), Retrieval Augmented Generation (RAG), vector search, embeddings, prompt engineering, agents, and model evaluation.
