Following the README, but can't get it working

Here is my .babelrc

{
  "presets": ["es2015", "stage-2"],
  "passPerPreset": true,
  "plugins": [
    ["typecheck", {
      "disable": {
        "production": true
      }
    }, "syntax-flow", "transform-flow-strip-types"]
  ]
}

And I'm getting a SyntaxError on

SyntaxError: Unexpected token, expected , (8:44)
   6 | const router = new express.Router();
   7 |
>  8 | router.param('jobId', (req, res, next, jobId: string) => {

Am I setup incorrectly?

Thanks for any help.
