Description For (USA) Software Engineer III

Walmart Global Tech's Marketplace Engineering team is seeking a Senior Software Engineer III to join their rapidly growing e-commerce platform. This role is within the Walmart Seller Fulfilled Group, which is transforming how third-party sellers handle fulfillment on Walmart's Marketplace platform. The team has achieved impressive 250% year-over-year growth and is tackling complex challenges in e-commerce and logistics.

The position offers an opportunity to work on high-impact projects including designing cost-efficient supply chains, developing real-time carrier performance dashboards, and building innovative capabilities for shipping protection and promotion platforms. You'll be part of a team that's revolutionizing global commerce at scale, working with cutting-edge technologies and distributed systems.

As a Software Engineer III, you'll be responsible for designing and implementing highly scalable backend systems, applying machine learning solutions, and collaborating with cross-functional teams. The role requires strong expertise in Java programming, distributed systems, and modern cloud technologies. You'll work in Walmart's Silicon Valley office in Sunnyvale, where you'll have access to both technical challenges and lifestyle benefits of the Bay Area.

This is an excellent opportunity for experienced engineers who want to make a significant impact while working on systems that serve millions of customers and sellers worldwide.
