We strive to provide a simple and seamless experience to our developers keeping developer productivity is our top priority.

We sustain millions of transactions per second, process petabytes of data, and enable tens of thousands of production deployments per day. We simplify the complexities of scale and unify the software development for all aspects of business, digital and physical.

We are developer’s developers. We provide and foster the cloud native culture to our organization.

• What you’ll do

• AI System Design & Development: Lead the architecture, development, and deployment of Gen AI and Agentic AI solutions, including LLMs (e.g., GPT, Gemini), RAG frameworks, and multi-modal models (text, image, video) for applications like knowledge retrieval, summarization, and dynamic real-time responses.

• Agentic Frameworks: Design and implement autonomous AI agents that utilize vector search technologies, prompt engineering, and orchestration to perform complex, multi-step tasks, such as automating business processes or enhancing conversational AI platforms.

• • Platform Engineering: Build reusable, scalable, and extensible microservices (e.g., using Fast API) and event-driven architectures (e.g., Kafka, WebSocket) to support Gen AI platforms, ensuring high performance and reliability.

• Model Optimization: Fine-tune and optimize Gen AI models for specific business needs using techniques like quantization, distillation, and prompt engineering to improve efficiency and accuracy.

• Collaboration: Work closely with cross-functional teams, including data scientists, machine learning engineers, product managers, and business stakeholders, to translate requirements into technical solutions and prioritize impactful AI-driven products.

• Technical Leadership: Mentor junior and senior engineers, conduct code reviews, and set high standards for engineering excellence, including adherence to DRY (Don’t Repeat Yourself) principles and CI/CD automation.

• • Operational Excellence: Support production operations through on-call rotations, troubleshoot high-impact issues, and ensure system scalability, availability, and performance in distributed environments.

• • Innovation & Research: Stay up-to-date with the latest advancements in Gen AI and Agentic AI, collaborate with applied researchers to integrate cutting-edge research into applications, and contribute to thought leadership within Walmart and the broader tech community
