Can't use Alternate Credentials to Run Start-Job jobs on Jenkins with PowerShell Plugin

Question

System: Windows Server 2012 R2 | PowerShell v4 | Jenkins v1.607 | 64-Bit Java Version 8u60

For whatever reason, I am able to login to the Windows server that Jenkins is running on, and execute the following code without issues:

Start-Job -Credential $Creds -ScriptBlock {Get-Process}
Get-Job | Wait-Job | Receive-Job

Upon trying to execute the same code within a Jenkins job, utilizing the PowerShell plugin, with the same user credentials I was using in $Creds, it fails without any helpful information. Credentials have been verified. This is the error that I get:

    [localhost] The background process reported an error with the following message: .
    + CategoryInfo          : OpenError: (localhost:String) [], PSRemotingTransportException
    + FullyQualifiedErrorId : 2100,PSSessionStateBroken

I used the Resolve-Error function, as found here, to try and get more information. Here was the output:

writeErrorStream      : True
PSMessageDetails      :

Still no helpful information. I'm at a loss as to what may be the issue, and have no idea how to proceed.
