The OddJob.Scheduler is responsible for execution of scheduled jobs.

Each scheduler is a dynamically supervised process that is created to manage a single timer and a job or collection of jobs to send to a pool when the timer expires. After the jobs are delivered to the pool the scheduler shuts itself down. The scheduler process will also automatically shutdown if a timer is cancelled with OddJob.cancel_timer/1. If a timer is cancelled with Process.cancel_timer/1 then the scheduler will eventually timeout and shutdown one second after the timer would have expired.
