Is this ebay job offer a scam?

Although Product Sourcing through eBay is legal, eBay gives you a warning on the bottom of the page. Read the link in the ad you posted here.

eBay: "If you sell using a product sourcer, remember that you never see the actual item, so it's important to make sure you're dealing with a reliable company. We recommend working with an eBay Certified Provider. Remember that you're always responsible for the item until it reaches the buyer in good condition."

Yes it's a scam. You do not know the company. Do not let anyone use your accounts. Don't set up any accounts for them. Don't ever agree to handle purchases and sales through you. You can check the eBay list of eBay Certified Providers. However, I doubt this company is on that list. Their ad shows several features of scam artists.
* They promise high pay for very few hours of work.
* They want to use your accounts instead of their own.
* You buy product using your account. You ship it, using your money.
* They promise to pay you back. (They often don't.) Or they promise to send you a check and ask you to cash it. (It's often a bad check.)
* You are out the money.

Legitimate businesses don't usually need a 3rd party to set up an account for them, and filter their money. They be able to have financial networks set up where they want to do business.

Please DO NOT do business with them.

I'm glad to see that you asked questions before you went further and got stuck with bad checks, purchases and shipments through your PayPal account, without reimbursement from this phony company.
