We’re partnering with a leading global alternative investment firm expanding its Linux support function in London. This is a hands-on role for an ambitious Linux Engineer to support a wide range of teams - trading, infrastructure, security, and systems operations. Operating with significant autonomy from the UK office, you’ll join a highly technical environment focused on Red Hat Linux, infrastructure automation, identity management, and cross-platform integrations. Prior experience in financial services or similarly regulated, high-stakes environments is strongly preferred, offering exposure to critical business infrastructure, front-to-back office systems, and a clear path for technical growth...

Key Responsibilities

• Provide day-to-day support and troubleshooting for Red Hat Enterprise Linux (RHEL) systems across multiple business units and technology platforms
• Monitor incident queues, prioritise requests and address support tickets efficiently, escalating where necessary
• Deploy, configure, and maintain Linux servers and associated storage, networking, and hardware components
• Maintain and enhance automation scripts and infrastructure-as-code processes using Ansible, Terraform, and Python/Bash
• Administer and troubleshoot identity and access management tools, including Active Directory integrations and Kerberos-based authentication
• Collaborate with Windows, Security, and Engineering teams to ensure system performance, integrity, and compliance
• Conduct detailed root cause analysis following incidents, develop corrective actions, and maintain updated operational documentation
• Manage filesystem configurations, NFS/CIFS mounts, and storage technologies including LVM and ZFS (where applicable)
• Participate in change control processes, release management, and cross-team project delivery
• Support hybrid on-prem and cloud infrastructure environments, contributing to continuous platform modernisation initiatives
• Participate in an on-call rotation (typically one week in every four), providing support for critical production systems out-of-hours

What You’ll Bring...

• 3-5 years’ experience supporting Linux infrastructure within a production environment, ideally as a second-role engineer
• Hands-on knowledge of Red Hat Enterprise Linux (RHEL) installation, administration, and performance optimisation
• Confident scripting capability with at least one language such as Bash or Python (flexibility on primary language; willingness to learn is highly valued)
• Experience with configuration management and automation tools, particularly Ansible and Terraform
• Grasp of identity access management fundamentals, with exposure to Kerberos or equivalent systems
• Experience with Kubernetes clusters and containerised workloads
• Familiarity with network services and protocols such as DNS, DHCP, TCP/IP, NFS/CIFS, Samba and related services
• Comfort with analysing system logs, monitoring performance metrics, and proactively resolving issues
• Organised, methodical, and able to produce high-quality technical documentation and troubleshooting guides
• Familiarity with cloud platforms such as AWS or hybrid cloud deployment
• (Preferred) Experience supporting Linux systems within financial services, trading, or other regulated, performance-driven industries
