Amazon has filed a lawsuit against Arthur Valdez, a veteran of the online behemoth, who last month was hired as executive vice president and chief supply chain and logistics officer of Target Corp.

The suit alleges that Valdez’s job, which begins on March 28, violates the terms of a non-compete agreement he signed while employed by Amazon.

The filing says that Valdez “cannot lead Target’s supply chain operations without referencing confidential information learned and developed by him at Amazon to drive superior performance in exactly the same areas” and asked the court to enforce the 18-month period that Amazon said prevents former employees from working for competitors in similar jobs.

Valdez was hired by Target on Feb. 29 to help it optimize its supply chain and leverage its nearly 1,800 stores. According to Target, Valdez has been charged with transforming the retailer’s supply chain, including planning, distribution and transportation.

“We have taken significant precautions to ensure that any proprietary information remains confidential and we believe this suit is without merit,” a Target spokeswoman said. “As this is pending litigation, we are not going to comment further at this time.”

A spokeswoman for Amazon said the company doesn’t comment on pending litigation.

Valdez spent 16 years at Amazon, most recently as vice president of operations, where he was focused on the company’s international supply chain expansion. He also held leadership positions across Amazon’s global and domestic supply chains, including transportation, fulfillment and logistics.

During his more than 20-year career, Valdez also held positions at Wal-Mart and Kmart.

At the time his appointment was announced, John Mulligan, executive vice president and chief operating officer of Target, said, “Target’s growth hinges on our ability to enhance the fundamental aspects of our business, starting with the supply chain. Arthur’s leadership experience will be a tremendous asset as we continue to drive improvements in end-to-end processes, including leveraging our stores to deliver a seamless experience for our guests.”
