You will want to capture the STATUS_UPDATE event from CloudWatch and feed that into a service like Lambda that could update a database, or whatever data source you are using to display job stats out.

Example of the Event Pattern

{
  "source": [
    "aws.mediaconvert"
  ],
  "detail-type": [
    "MediaConvert Job State Change"
  ],
  "detail": {
    "status": [
      "STATUS_UPDATE"
    ]
  }
}

Example of what the Status Update event payload looks like: 

{
    "version": "0",
    "id": "ABC",
    "detail-type": "MediaConvert Job State Change",
    "source": "aws.mediaconvert",
    "account": "111122223333 ",
    "time": "2021-02-18T17:52:32Z",
    "region": "us-west-2",
    "resources": [
        "arn:aws:mediaconvert:us-west-2:111122223333 :jobs/1613670689802-emcngz"
    ],
    "detail": {
        "timestamp": 1613670752653,
        "accountId": "111122223333 ",
        "queue": "arn:aws:mediaconvert:us-west-2:111122223333 :queues/Default",
        "jobId": "1613670689802-emcngz",
        "status": "STATUS_UPDATE",
        "userMetadata": {},
        "framesDecoded": 2024,
        "jobProgress": {
            "phaseProgress": {
                "PROBING": {
                    "status": "COMPLETE",
                    "percentComplete": 100
                },
                "TRANSCODING": {
                    "status": "PROGRESSING",
                    "percentComplete": 2
                },
                "UPLOADING": {
                    "status": "PENDING",
                    "percentComplete": 0
                }
            },
            "jobPercentComplete": 7,
            "currentPhase": "TRANSCODING",
            "retryCount": 0
        }
    }
}

MediaConvert provides granular percentages per phases the job is in (probing input, transcoding, and uploading outputs) as well as an overall percentage. The one that is displayed on the MediaConvert Console UI is the jobPercentComplete, and would probably be the one you want to capture.
