About Team

Walmart is a multi-national people led tech powered omnichannel retailer with over 2.2M associates. At People Support Tech, EBS we help, support and empower the Walmart's HR function with AI and GenAI solutions to improve productivity, harnessing the opportunities for growth, focusing on well-being and cultivating cultures of belonging for all Walmart's associates. Our team is responsible for transforming the People Help Center experience that is being leveraged by 2.2M associates through different voice and chat channels.

The vision is to deliver a radically efficient, deeply empathetic People Services experience where associates get what they need the first time—with clarity, speed, and zero unnecessary effort. By leveraging AI, the system anticipates and resolves associates queries on HR functions like Benefits, Payroll etc. before they become human contacts, ensuring proactive support for associates. Additionally, human agents are empowered with context, judgment support, and automation, allowing them to deliver faster, more accurate assistance while focusing on meaningful interactions. This approach enhances productivity, cultivates a culture of belonging, and completely transforms the HR Help Center Experience for all Walmart's associates.

Our team is seeking a highly skilled Senior Data Scientist to help design, build, and scale AI/ML and GenAI solutions in production. In this hands-on individual contributor role, you will bring strong applied experience and a deep passion for building AI-powered products that deliver real business impact. You will contribute to the development of enterprise-scale GenAI and AI systems, apply modern generative AI techniques, and collaborate closely with data scientists, machine learning engineers, and software engineers in a highly collaborative environment. You will also play a key role in shaping technical solutions by contributing to system architecture, aligning AI/ML designs with business and scalability goals, and ensuring solutions are robust, responsible, and production-ready. Additionally, the role involves close collaboration with cross-functional partners and upholding high engineering standards through thoughtful design and code reviews.

Walmart's Enterprise Business Services (EBS) is a powerhouse of several exceptional teams delivering world-class technology solutions and services making a profound impact at every level of Walmart.

As a key part of Walmart Global Tech, our teams set the bar for operational excellence and leverage emerging technology to support millions of customers, associates, and stakeholders worldwide. Each time an associate turns on their laptop, a customer makes a purchase, a new supplier is onboarded, the company closes the books, physical and legal risk is avoided, and when we pay our associates consistently and accurately, that is EBS. Joining EBS means embarking on a journey of limitless growth, relentless innovation, and the chance to set new industry standards that shape the future of Walmart.
