Hi @rynkowsg, welcome to the CircleCI Community! In our 2.1 configuration you can use jobs multiple times in your workflows section. You can read more here: CircleCI 2.1 Config Overview under the “Jobs” section.
Please note our 2.1 Configurations require you have pipelines enabled, which can be turned on in your Advanced Settings.
Can you try changing version: 2.0 to version: 2.1 at the top of your configuration, turn on pipelines and run a fresh build? Please let us know if this works for you.
