I have a job that looks like this:

jobs:
- name: ingest_api_services
  tasks:
  - tap-google-search-console target-bigquery
  - tap-google-analytics target-bigquery

is it possible to make the tasks run in parallel?

Not yet, but if you're using Airflow with the meltano dag generator , and feeling adventurous - the change to get parallel task there is probably very small - https://github.com/meltano/files-airflow/issues/21
