Ecolab – Associate AI Engineer

The Associate AI Engineer position at Ecolab is an entry-level opportunity for candidates who want to build their careers in Artificial Intelligence, Generative AI, Large Language Models, and intelligent application development. Based in Bangalore, the role focuses on supporting the development and deployment of AI-powered applications that can solve practical business problems. The position provides exposure to modern AI engineering concepts including foundational AI APIs, embedding models, vector databases, prompt engineering, language-model-integrated services, and agentic workflows. As an Associate AI Engineer, you will work under the guidance of an AI Engineering Manager while contributing to real-world technology initiatives. This makes the role particularly relevant for recent graduates and professionals with up to two years of experience who want hands-on exposure to production-oriented GenAI engineering.

A key focus of the role is helping transform emerging AI capabilities into useful, reliable applications. The Associate AI Engineer will support the creation of GenAI applications, AI services, agentic workflows, and retrieval-based solutions, while working with technologies that enable language models to interact with enterprise data and applications. Vector databases and embedding models are particularly important because they allow AI systems to retrieve relevant information and provide more contextually useful responses. Prompt engineering also forms an important part of the position, helping engineers structure instructions and interactions for language models. The role therefore combines software engineering fundamentals with modern AI development practices, giving early-career professionals an opportunity to understand how LLM-powered solutions move from experimentation toward production-aligned systems.

Beyond individual AI components, the position offers exposure to the broader engineering lifecycle involved in delivering intelligent applications. Candidates will work with experienced AI engineers and contribute to solutions that require experimentation, integration, testing, refinement, and deployment. Ecolab describes the role as supporting both development and deployment, meaning candidates can gain practical experience beyond simply building machine-learning models in notebooks. The position sits within Ecolab's Information Technology organization and reports normally to an AI Engineering Manager. With Ecolab operating across industries including water, hygiene, infection prevention, food, beverage, and manufacturing, AI engineers can work in an environment where technology is connected to large-scale operational and business challenges.
