IT Senior Architect - Linux & Open-Source

Reports to: Director - Enterprise Solutions, Cloud & Service

Role Overview

We are looking for an experienced IT Architect – Linux & Open Source
Infrastructure to design, evolve and govern our Linux server landscape and the
broader open-source technology stack that underpins our business-critical
applications. You will own the technical architecture end-to-end - from
on-premises data centers to hybrid and cloud environments - and act as the
technical authority for standards, security and scalability across the platform.

Beyond the OS layer, you will shape our open-source technology strategy: which
tools and platforms we standardize on, how we evaluate open source vs.
proprietary/commercial options and how we manage the licensing, support and
community engagement that come with running open source at enterprise scale.

The IT operations are outsourced to an external service provider. This role is
therefore architecture- and governance-focused rather than hands-on operational,




with a strong emphasis on steering and collaborating with the outsourcing
partner. You will set direction, but you will also get into the weeds of
automation, hardening and performance tuning when it matters.

Key Responsibilities

* Design and maintain the target-state architecture for Linux server and
desktop infrastructure (e.g. RHEL/CentOS/Oracle Linux, SUSE, Ubuntu/Debian,
as applicable) across on-prem, virtualized and cloud environments

* Own the architecture and roadmap for the broader open-source infrastructure
stack (automation, orchestration, observability, CI/CD, identity, data
platforms)

* Define standards for OS builds, patching, hardening and lifecycle management
and ensure compliance across the estate

* Architect and oversee infrastructure automation (configuration management,
provisioning, CI/CD for infrastructure) to enable consistent, repeatable
deployments

* Lead the evaluation and integration of virtualization and containerizat
