If anyone needs this, here is what I was able to come up with - This will return the # of currently executing jobs of the specified Type.
public static int GetCurrentlyExecutingJobCount(Type jobType)
IScheduler scheduler = JobsManager.GetScheduler();
var jobs = scheduler.GetCurrentlyExecutingJobs();
var jobCount = 0;
foreach (JobExecutionContext job in jobs)
if (job.JobDetail.JobType.FullName.Equals(jobType.FullName, StringComparison.OrdinalIgnoreCase))
