Amazon.com plans to cut 263 jobs at its parenting products unit Quidsi as the unit restructures to turn the tide on continued unprofitability.

The New Jersey-based subsidiary operates Diapers.com, Soap.com and other Web sites.

“We have worked extremely hard for the past seven years to get Quidsi to be profitable and unfortunately we have not been able to do so,” an Amazon spokeswoman said this week.

Quidsi’s software development team will focus on building technology for the AmazonFresh grocery delivery service the statement said.
