SR Gen AI developer-

This role will work closely with product, engineering, and data teams to build scalable AI features that are reliable, performant, and secure in production environments.

Responsibilities

• Design and implement end-to-end AI features, including RAG systems, agent workflows, embeddings pipelines, and fine-tuned LLM applications.

• Build and maintain data ingestion, chunking, embedding, retrieval, and prompt orchestration pipelines.

• Fine-tune and evaluate open-source and proprietary LLMs using techniques such as LoRA, QLoRA, PEFT, and supervised fine-tuning.

• Deploy and serve custom LLMs in Azure environments using Azure Machine Learning, AKS, Container Apps, or related services.

• Optimize inference performance using quantization, batching, model parallelism, and GPU-aware serving strategies.

• Work with model formats such as Safetensors, GGUF, ONNX, and TensorRT for efficient loading, portability, and deployment.

• Build scalable APIs and services for LLM inference, streaming responses, and model orchestration.

• Implement model monitoring, logging, evaluation, prompt testing, and feedback loops.

• Collaborate with product managers and stakeholders to translate business requirements into AI capabilities.

• Explain technical trade-offs clearly to non-technical audiences, including model size, quantization, latency, cost, and accuracy.

All contractor resources are expected to demonstrate baseline proficiency in enterprise-approved AI tools as part of their day-to-day responsibilities. This includes, but is not limited to:

• Consistent Use: Maintain a minimum of 90% weekly usage of AI tools such as GitHub Copilot, Microsoft 365 Copilot, and other GenAI platforms approved by the enterp
