Walmart’s Tech EVP Reveals Key Traits He Seeks in Engineers: Fundamentals and Continuous Learning

Walmart’s Executive Vice President of Global Tech Platforms, Sravana Karnati, emphasizes two core qualities when hiring engineers: strong computer science fundamentals and the ability to learn continuously. With over 25 years of experience at companies like Amazon, Disney, and Oracle, Karnati believes technical expertise goes beyond knowing specific programming languages like Java or C++. Instead, he focuses on whether candidates grasp core principles such as algorithms, system architecture, dependencies, and risk management. “Does a person understand the fundamentals of computer science?” Karnati asked. He stresses that while specific tools and languages may change over time, a solid foundation enables engineers to adapt and thrive in evolving environments. For software developers and engineering roles, this deep understanding is essential, even as AI-powered tools like large language models (LLMs) help boost productivity. According to Karnati, these tools enhance efficiency but cannot replace the need for fundamental knowledge of how systems work. He also notes that while a computer science degree is not a strict requirement, candidates should demonstrate technical aptitude. Karnati himself holds a doctorate in chemical engineering but has spent decades working as a computer scientist. He believes professionals from diverse backgrounds—such as industrial engineering with a technical focus—can excel in tech roles, especially in operations, where operational rigor and problem-solving skills are key. Beyond technical knowledge, Karnati places high value on the ability to learn and grow. He looks for evidence that candidates have actively sought out new experiences—through internships, side projects, or varied coursework—that show a broad curiosity and willingness to adapt. “The trick is keeping up with the evolution of technology and continuing to retrain yourself,” he said. He points to long-term industry veterans who have stayed relevant by consistently learning and evolving. This focus on adaptability reflects a wider shift among tech leaders. As AI reshapes the workplace, companies increasingly prioritize agility and lifelong learning. Waze co-founder Uri Levine has said the most important skill today is the ability to adapt, while Cloudflare CEO Matthew Prince highlighted the value of hiring people with broad, interdisciplinary skill sets. Karnati’s own work at Walmart—developing Wibey, an AI-powered tool designed to help developers automate repetitive coding tasks and manage compliance—illustrates the company’s emphasis on smart, adaptable talent. The goal is not just to use AI tools, but to build systems that are efficient, sustainable, and scalable. Ultimately, Karnati seeks engineers who can think critically, learn quickly, and grow with the technology they help shape.
