List of generic Type

I have a generic class and I want to create a list of it. and then at run time I get the type of the item

Class

public class Job<T>
{
    public int ID { get; set; }
    public Task<T> Task { get; set; }
    public TimeSpan Interval { get; set; }
    public bool Repeat { get; set; }
    public DateTimeOffset NextExecutionTime { get; set; }

    public Job<T> RunOnceAt(DateTimeOffset executionTime)
    {
        NextExecutionTime = executionTime;
        Repeat = false;
        return this;
    }
}

What I want to achive

List<Job<T>> x = new List<Job<T>>();

public void Example()
{
    //Adding a job
    x.Add(new Job<string>());

    //The i want to retreive a job from the list and get it's type at run time
}
