Abstract: An orchestration system of or otherwise available to a web platform centralizes the execution of workflow components of a workflow associated with a job posting hosted by the web platform using various software services internal and/or external to the web platform. The workflow components and attributes thereof are determined based on the job posting. Domain-specific language (DSL) instructions for the various workflow components are generated. First DSL instructions are invoked by the orchestration system to cause an execution of a first workflow component of the workflow by a first software service. The orchestration system obtains an output of the first workflow component, such as values of relevant attributes, and, based on the output and in some cases information derived other than from the first workflow component, invokes next DSL instructions to cause an execution of a next workflow component of the workflow by another software service.
