Senior Software Engineer – Identity and Access Management

What you'll do

Are you ready to be at the heart of the daily digital experience of thousands of researchers and engineers, as CERN’s Identity and Access Management Service Manager?

You will join the Platforms & Workflows group in the IT Department, where ~30 experienced engineers are responsible for providing a wide spectrum of centrally managed services, such as identity and access management, platforms for developers and researchers, as well as solutions for content authoring and websites hosting.

CERN’s Identity and Access Management Service underpins the digital lifecycle ecosystem for all CERN employees and collaborators. It is a custom-built .NET platform that provisions and manages user identities, accounts, authorisation groups, eligibility for certain services, and software integrations with CERN’s Single Sign-On.

It also ensures that digital assets (e.g. websites, databases, storage, and other technical resources) created during a person’s time at CERN are handled correctly as they change roles or leave the organisation. This is a mission-critical system for CERN where your skills as a Full Stack Developer will directly contribute to a smooth online experience.

Manage service operations: configuration, testing, deployment, troubleshooting, bug fixing.
Engage with the user community to gather requirements and enhance the service to meet the evolving needs of the organisation.
