# IJob

> An interface that allows you to schedule a single job that runs in parallel to other jobs and the main thread.

## Definition

* **Type:** Interface
* **Namespace:** [Unity.Jobs](/engine/6000.7/script-reference/unity/jobs.md)
* **Assembly:** UnityEngine.ManagedKernelModule

```csharp
[JobProducerType(typeof(IJobExtensions.JobStruct<>))]
public interface IJob
```

## Remarks

After a job is scheduled, the job's Execute method is invoked on a worker thread. You can use the returned [JobHandle](/engine/6000.7/script-reference/unity/jobs/jobhandle.md) to make sure that the job has completed. You can also pass the JobHandle to other jobs as a dependency, which ensures that jobs are executed one after another on the worker threads.
