You can use ETS and Mnesia, and overall it is built to be distributed so you can pass messages between processes/nodes without needing something like RabbitMQ.

Most of the time Erlang and OTP provide what you need already without having to reach for an external tool. (Obviously depending on your use case)

Furthermore, job processing is much easier with Erlang because the processes and the scheduling mechanism - there could be no job, only processes doing their things.
