Senior Infrastructure Engineer — OpenStack
Pubblicato il 10-09-2026 - Azienda Anonima in Frosinone
SENIOR INFRASTRUCTURE ENGINEER - OPENSTACK & CLOUD SYSTEMS We are looking for a Senior Infrastructure Engineer to serve as a technical leader within our Infrastructure Team, driving the design, evolution, and operation of the software-defined infrastructure that powers some of the largest HPC and AI clusters in Europe. OpenStack is the primary production platform today; the role owns the broader Linux, Kubernetes, and bare-metal systems stack around it.
We hire first for depth of systems engineering — the ability to understand why something does not work, not just how to restart it: reading an strace, reading the source of a service, isolating a kernel or network issue, and driving a fix upstream when needed. A strong engineer with this foundation who knows OpenStack — or an equivalent large-scale production platform — is exactly who we are looking for; the specific stack can be learned, the way of reasoning cannot.
The successful candidate will be responsible for the architecture and operations of cloud control planes in large-scale production environments, ensuring reliability,
scalability, and operational continuity. They will lead critical technical initiatives, plan and execute infrastructure upgrades and migrations, collaborate with leading technology vendors to manage escalations, and provide technical leadership to the team through mentoring, knowledge sharing, and best practices.
KEY RESPONSIBILITIES:
- Own the architecture and day-2 operations of OpenStack control planes for clusters of hundreds of nodes today, with a growth path to 1000+ nodes at upcoming public and private AI Factories: uptime, capacity, performance, and security KPIs.
- Diagnose and resolve complex, cross-layer production issues down to the root cause — kernel, systemd, storage, and network stack — using tools such as strace, perf, and packet capture, reading service source code where needed and contributing fixes upstream.
- Design and operate the advanced networking underpinning high-
