Question

How do I Start a job of a function i just defined?

function FOO { write-host \"HEY\" } Start-Job -ScriptBlock { FOO } |
Receive-Job

Receive-Job: The term \'

An improvement to @Rynant's answer:

You can define the function as normal in the main body of your script:

Function FOO 
{ 
  Write-Host "HEY" 
} 

and then recycle this definition within a scriptblock:

$export_functions = [scriptblock]::Create(@"
  Function Foo { $function:FOO }
"@)

(makes more sense if you have a substantial function body) and then pass them to Start-Job as above:

Start-Job -ScriptBlock {FOO} -InitializationScript $export_functions| Wait-Job | Receive-Job

I like this way, as it is easier to debug jobs by running them locally under the debugger.
