About audienzz

Audienzz is a Swiss digital advertising company developing and operating technology for publishers, advertisers and media partners. Audienzz is part of the NZZ group and operates independently, with its own technology decisions.

Our engineering organisation runs a highly automated infrastructure platform based on Linux, Kubernetes, Ceph and Bazel. The platform runs more than 200 stateful and stateless services on self-managed bare-metal infrastructure.

We operate the underlying infrastructure ourselves and are looking for an experienced Platform Engineer to strengthen our platform team.

What we offer:

• A technically challenging role with substantial ownership of a sophisticated production infrastructure and build platform.

• Direct influence on platform architecture and technology decisions, with short decision paths.

• Close collaboration with experienced software and platform engineers across the full infrastructure stack.

• An engineering culture focused on reliability, automation and continuous improvement.

Practical details:

Location: Preferably Zurich. Remote work from elsewhere in Europe is possible for the right candidate; regular presence in Zurich is required.

On-call: Production alerts are routed to a Slack channel and handled by the platform team. There is currently no formal on-call rota; defining a sustainable on-call model as the team grows is part of this role.

Interested?

Send us your CV together with a few sentences about the most challenging infrastructure environment or problem you have owned end to end, including where you have operated self-managed Kubernetes and Ceph, and at what scale.
