IT Senior Architect - Linux & Open-Source

IT Senior Architect - Linux & Open-Source 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

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 containerization platforms (e.
