Well, I have a solution that works. I gave up on the FTP task. Instead, I create a batch file on the FTP server. I have shared out the folder where the FTP client resides (i.e., WinSCP). The batch file gets called by an Execute Process task in the package. The whole thing works as a job.

This didn't work for me before because I had failed to share out the folder where the FTP client was. Actually, I was trying to "pushd" into the FTP server, then run the batch file. I kept encountering errors with the "pushd" so just gave up that strategy.

The batch file resembles:

"\\myFTPServer\Putty\WinSCP.exe" /script = "\\myFTPServer\temp\Myscript.sc"

The script file resembles:

option batch on

option confirm off

open ftp://UserName:Password@FTPServer:21

put "\\SomeNetworklocation\TheFile.csv"

close

My advice to SSIS developers trying to get the FTP to work as a job is give up on the FTP task and create a batch file.
