Infosys is seeking a hands‑on Gen AI / Agentic AI Lead to drive the development and deployment of next‑generation AI solutions using Large Language Models (LLMs), Retrieval‑Augmented Generation (RAG), and Agentic AI frameworks. The role is ideal for a mid‑level engineer with strong technical depth, a passion for building, and the ability to lead small teams or workstreams in a fast‑paced, innovation‑driven setting.

Key Responsibilities

Design, develop, and deploy Gen AI applications using LLMs and agentic frameworks (e.g., LangGraph, AutoGen, Crew AI).

Fine‑tune open‑source and proprietary LLMs using techniques such as LoRA, QLoRA, and PEFT.

Build and optimise RAG pipelines with hybrid retrieval, semantic chunking, and vector search.

Integrate Gen AI solutions with cloud‑native services (AWS Bedrock, Azure OpenAI, GCP Vertex AI).

Work with unstructured data (PDFs, HTML, audio, images) and multimodal models.

Implement LLMOps practices including prompt versioning, caching, observability, and cost tracking.

Evaluate model performance using tools like RAGAS, DeepEval, and FMeval.

Collaborate with product managers, data engineers, and UX teams to deliver production‑ready solutions.

Mentor junior engineers and contribute to code reviews, design discussions, and best practices.

Qualifications

Location: Must be within commuting distance of Mississauga, ON, or willing to relocate.

Bachelor’s degree in Computer Science, AI/ML, or related field, or an accredited foreign equivalent; additional experience may substitute education.





5 years of experience in software engineering or data science, with 2–3 years in Gen AI or LLM‑based systems.

Strong Python programming skills and experience with ML/AI libraries (Hugging Face Transformers, LangChain, PyTorch).

Hands‑on experience with vector databases (FAISS, Pinecone, Weaviate, Azure AI Search).

Familiarity with cloud platforms and Gen AI services (AWS, Azure, GCP).

Experience with REST API development (FastAPI, Flask) and containerisation (Docker).

Solid understanding of AI governance, model safety, and prompt engineering.

Experience with CI/CD pipelines and DevOps tools (GitHub Actions, Jenkins, Terraform).

Familiarity with front‑end integration (React, Angular, TypeScript) and GraphQL APIs.

Knowledge of model interpretability, bias mitigation, and human‑in‑the‑loop systems.

Experience with multimodal models and perception systems (vision + language).

Exposure to agentic workflows and autonomous agents.
