Senior Software Engineer – AI
Walmart · Sunnyvale, CA
- Design and integrate AI/ML-powered features into Java-based microservices — model inference endpoints and intelligent data pipelines — consuming GenAI / LLM APIs (OpenAI, Anthropic, Azure OpenAI) for Walmart's retail platform at scale.
- Built and optimized Retrieval-Augmented Generation (RAG) solutions on vector databases (Pinecone, FAISS) and enterprise data; shipped REST APIs integrating third-party AI services for product recommendations and automated catalog operations.
- Developed React frontends with AI-assisted UX patterns; partnered with data science to deploy, monitor, and scale models in the cloud following MLOps practices.
- Own L2/L3 production support for full-stack AI applications on AWS and GCP — root cause analysis, incident triage, and SLA/SLO adherence.
- Enabled self-healing systems via anomaly detection and auto-remediation; engineered permanent fixes that reduced incident recurrence by 40%.
- Applied prompt engineering with LangChain and LangGraph orchestration; enforced security, governance, and responsible-AI practices; maintained runbooks and operational procedures.
