About the Role

This is a Full Stack Software Development Engineer role within a team building customer- and workforce-facing conversational AI solutions, responsible for building next-generation conversational AI, intelligent search, and knowledge systems that power customer and associate experiences across multiple channels. This role requires hands-on expertise in designing, developing, and productionizing scalable, secure, and enterprise-grade GenAI solutions across cloud and on-premise environments.

Key Responsibilities

● Design and develop LLM-powered applications for conversational AI, knowledge retrieval, and insights delivery

● Build and orchestrate end-to-end GenAI pipelines, including prompt engineering, RAG, and agent-based workflows

● Develop and manage LLM agents (tool usage, API integration, function calling)

●

Integrate LLMs across cloud and on-prem/open-source environments

● Build RAG data pipelines (chunking, indexing, metadata enrichment)

●

Implement evaluation frameworks covering accuracy, hallucination, latency, safety, and validation (LLM-as-judge,

human-in-loop)

● Apply AI safety and guardrails, including prompt injection prevention and response validation

● Optimize models using prompt tuning, embeddings,



and fine-tuning techniques

● Develop multimodal conversational experiences (text and voice)

● Build scalable backend services using microservices and REST APIs

● Enable observability (latency, token usage, cost, drift, quality monitoring)

● Contribute to POCs, experimentation, and adoption of emerging GenAI technologies

Required Skills

Core Engineering
