Using python-rq with Zope - zope

Question

I'm trying to use Python-RQ with Zope by calling an external method (for background tasks) from ZMI after a certain operation. The file called by external method resides in Extensions. It initialises connection to Redis and imports a module that runs the background tasks. The question is where should this to be imported file be placed ? Python-RQ does not seem to recognise if I put it inside Products directory. It throws no module named Products.xyz. Below is the code snippet
from redis import Redis
from rq import Queue
from Products.def_update_company_status import ae_update_company_status
q = Queue(connection=Redis())
def rq_worker(context):
q.enqueue(ae_update_company_status)
return 'DONE'
The rq_worker function is invoked by the external method.
Below is the error
18:12:40 default: Products.def_update_company_status.ae_update_company_status() (4b2b5c81-e329-4031-a3e7-b9b1bb198278)
