How do I display grouped results in an EmberJS Application

I've created a simple EmberJS application that lists jobs from a headless CMS. The jobs data from the backend is in this format

[
   {
      "id": "1234",
      "description": "Test description"
      "category": "Human Resources"
   },
   {
      "id": "4321",
      "description": "Test description"
      "category": "Human Resources"
   },
   {
      "id": "5678",
      "description": "Test description"
      "category": "Information Technology"
   }
]

My app displays the results in the order that they're returned as expected but I'd like to group the results by category so that the results are displayed like this:

Human Resources

• 1234
• 4321

Information Technology

• 5678

Thanks in advance for any help.

Note: I'm using EmberJS version 3.19
