Opening of an LD post in DI-CSO: Identity Federation Manager

Type of notice
Internal Mobility

The IT department will publish soon on the CERN job portal the following Computing Engineer job:

Identity Federation Manager for the Academic Community in the Departmental Infrastructure Group, Computer Security Team (IT-DI-CSO).

With the steadily growing community of HEP institutes collaborating with CERN and contributing to joint projects (like the WLCG; but also with the widening of CERN’s computing resources to other sciences (HelixNebula, e.g. CERN as a cloud service provider), the current model of providing every participant with a CERN computing account does not scale anymore. Instead, federated identities, i.e. computing accounts issued by individual universities and institutes themselves, which are subsequently permitted to access CERN’s computing resources are the best alternative currently. However, to embark on such an alternative, tight coordination of the technical implementation and related subjects like trust, vouching, security, data privacy and data dissemination (“attributes”) are necessary. Currently on-going activities in this domain are REFEDS (, EduGAIN (, AARC (, and Sirtfi ( to name a few.

You will join

The CERN Computer Security Team (, which is mandated to secure and protect all aspects of the computing infrastructure of CERN as well as its operations and reputation against any kind of cyber-threats.


As Identity Federation Manager in the IT department, you will liaise with universities, institutes and other relevant stakeholders worldwide in order to drive forward an efficient, flexible, trustworthy and secure enabling of identity federation accounts at CERN. This includes the deployment of the current policies, negotiation and implementation of new policies, and the co-ordination of any (other) aspect which enhances the trust, security, and data privacy principles within the corresponding federations. Close contact with the WLCG will also be beneficial since identity federations have strong similarities to the policy bodies governing the WLCG.

As a Service Manager, you will be in charge of the implementation and integration of the different services and tools to fulfil the practical objectives of Federation: Integration with CERN Single Sign-on, integration of multifactor tokens when available, design and implementation of a new fine-grained authorization service taking into account Federated Identities, WLCG support, etc.

As a member of the Computer Security Team, you are also supposed to participate in the CERN CERT (Computer Emergency Response Team) and contribute to the resolution of computer security incidents.
