Sam's Club has hired about 100 technology employees in the Dallas area for a new office in downtown Dallas.

Sam's, the warehouse club division of Walmart, has leased 45,000 square feet in a renovated historic building at 603 Munger Ave., in the West End area of downtown Dallas.

Sam's is working on a new concept store that it plans to open this fall on Lower Greenville in a space where Walmart had operated a Neighborhood Market until early 2016. The company hasn't said a lot about it, but plans for it to be a technology-driven shopping experience.

The move into the new technology office will be completed in August, said Walmart spokeswoman Anne Hatfield. These employees have been working in co-working spaces and out of the Southlake Sam's Club, she said. Granite Properties has spent $77 million to renovate the seven-story building. It dates back to 1903, and Granite renamed it Factory Six-03. The 215,000-square-foot building's other tenants include the innovation lab for Richardson-based Blue Cross Blue Shield.

This is a new office, separate from other technology operations that Sam's and Walmart have in San Bruno, Calif. and at its headquarters in Bentonville, Ark., Hatfield said. It will be the only Sam's office solely devoted to technology work, she said.

The merging of e-commerce with store operations and technology seem to touch every part of a retailer's operations these days. The changing landscape is forcing companies like Walmart to expand its own technology staff and to create partnerships with other companies.

Last week Walmart said it had entered into a partnership with Microsoft to accelerate its digital transformation and use it as its preferred cloud provider.

In April, Walmart opened an emerging technologies office in Plano, also in a Granite building, to work on new systems to improve store operations. A similar office opened in Austin in February.

In January, Sam's Club closed 63 stores and is converting 12 of them to e-commerce fulfillment centers.
