Senior Platform Engineer

We are looking for an experienced Platform Engineer to join our growing team in Milan and help shape the future of our flagship project, Colosseum, one of Europe’s most powerful AI supercomputers, currently in development.

Designed to run our proprietary AI models at scale, it forms the compute backbone behind the intelligence we deliver to the world’s most demanding industries. In this role, you will play a key part in ensuring optimal resource utilization across our AI infrastructure. You will build and operate the foundational platform capabilities required to orchestrate workloads and resources with precision and efficiency. Furthermore, you will be responsible for scaling and dynamically redistributing resources across tenants while integrating critical infrastructure metrics into the resource management framework to enable intelligent scheduling and optimization. You will also work closely with Site Reliability Engineers and AI Cloud Engineers to design, implement, and continuously improve the platform. You will embed security controls directly into the platform foundation by implementing firewalls, enforcing least-privilege access policies, and applying network hardening practices, ensuring that security is built in from the ground up—before code is even deployed.
