Systems and methods are disclosed for batch job execution. In some embodiments, a method may include: executing a plurality of service instances, each service instance being configured to execute jobs stored in a database; and by a first service instance of the plurality of service instances, identifying a job stored in the database, determining that no service instance of the plurality of service instances other than the first service instance has initiated execution of the job, generating an execution timestamp having a granularity of one second or longer, recording the generated execution timestamp in the database such that the execution timestamp is associated with the job, and executing the job. The service instances other than the first service instance may be configured to avoid execution of the job upon determining that a respective system time matches the execution timestamp to the granularity of the execution timestamp.
