Examples related to secure computing systems are disclosed. In one example, a method includes, at a local agent computing device, sending to a remote work scheduling computing device a work context of the local agent computing device, the work context describing a set of work that the local agent is configured to execute, and polling a remote work depository for work compatible with the work context. The method further includes receiving a response from the remote work depository identifying a job within the work context, the job being requested by a computing device other than the remote work scheduling computing device, and executing the job.
