There are two causes for this:
1. DB server is short on storage and so the TEMP tablespace can't extend to the size it has been allocated.
2. The job is requiring more TEMP space than has been allocated.
When a new segment is created, Oracle uses temporary extents to initially build it before it converts the extent to a permanent value. If there is not enough tablespace, it results in the Oracle error which in turn causes the job to fail.
