Colleges and Affiliated Institutions Advertising System (CAIAS)¶
This page gives an overview of the Colleges and Affiliated Institutions Advertising System (CAIAS), describing its current status, where and how it's developed and deployed, and who is responsible for maintaining it.
Danger
CAIAS uses technology, coding standards, and deployment methodologies which are not endorsed by the TDA and not standard practice for the DevOps team.
Service Description¶
Allows non-central institutions to advertise jobs on the central jobs.cam.ac.uk site, providing an admin UI which allows job adverts to be recorded and a REST API which allows these adverts to be fetched and displayed on jobs.cam.ac.uk under the category "College and affiliated institution jobs".
Service Status¶
CAIAS is currently live.
Note
The current service requires complete re-development or decommission. Work is currently (Q2-2024)
being completed to migrate the existing CAIAS deployment to GCP as a means of continuing to offer
the service in the interim.
Contact¶
Technical queries and support should be directed to hr-systems-development@uis.cam.ac.uk and will be picked up by a member of the team working on the service. To ensure that you receive a response, always direct requests to hr-systems-development@uis.cam.ac.uk rather than reaching out to team members directly.
Issues discovered in the service or new feature requests should be reported to servicedesk@uis.cam.ac.uk
Environments¶
CAIAS is currently deployed to the following environments:
| Name | URL |
|---|---|
| Production | https://hrsystems.admin.cam.ac.uk/caias/ |
| Staging | No staging environment deployed |
| Development | No development environment deployed |
Staging and development environments will be provisioned as part of the migration to GCP.

The source code for CAIAS is spread over the following repositories:
| Repository | Description |
|---|---|
| Application Server | The source code for the main application server |
| Infrastructure Deployment | The Terraform infrastructure code for deploying the application server to GCP |
