Job Summary

We are seeking a highly experienced Senior / Lead Linux Engineering Support Engineer to lead and develop a small team supporting engineering systems within a fast-paced AI-focused environment.

This role combines deep Linux expertise with strong leadership, automation, and DevOps practices to ensure systems are reliable, scalable, and supportable at scale. A key aspect of the role is establishing and operating within a configuration-as-code environment, where system configuration and operational processes are managed through automation, pipelines, and source control rather than manual administration.

You will be responsible for leading incident response, driving operational improvements, and setting standards for how Linux systems are managed and supported across the organisation.

While the role includes leadership responsibilities, it will initially require a hands-on approach, including direct involvement in troubleshooting, system support, and automation efforts, while building team capability and scaling processes.

Working closely with engineering teams, platform engineers, and infrastructure specialists, you will ensure systems remain stable, performant, and aligned with evolving business and product delivery needs.

The Team

You’ll be joining a multi-disciplinary team with strong technical skills and a very supportive culture. We work closely together, regularly share knowledge, and your skills will make a direct impact on our business. It’s an exciting and pivotal moment for us right now, with plenty of new projects ahead. If you're looking to solve interesting problems and see your work deliver real-world results, this is the team for you.

Responsibilities and Duties

• Lead, mentor, and develop a team of Linux Engineering Support Engineers, establishing clear roles, responsibilities, and ways of working
• Own and oversee support for Linux-based systems and engineering environments, ensuring stability, performance, and availability
• Act as an escalation point for complex technical issues and outages, providing hands-on support where required
• Diagnose and resolve high-impact system and interoperability issues across mixed and distributed environments
• Perform hands-on investigation and troubleshooting to understand issues and drive effective solutions
• Lead incident response activities, including triage, coordination, and resolution
• Own and drive Root Cause Analysis (RCA) processes, ensuring preventative improvements are identified and implemented
• Establish and improve incident management processes, driving operational maturity and reliability
• Drive adoption of automation and configuration-as-code practices across Linux systems
• Ensure system changes are delivered through controlled, auditable processes wherever possible
• Oversee development and implementation of automation solutions for system management and operational tasks
• Promote and enforce use of Git-driven workflows and CI/CD pipelines for configuration and operational processes
• Identify and prioritise opportunities to reduce manual effort through automation and improved tooling
• Work closely with engineering teams to support development environments and system requirements
• Act as a senior technical liaison between engineering teams and infrastructure/platform functions
• Support onboarding of new systems, services, and environments using standardised and automated approaches
• Ensure system configurations remain consistent and aligned with defined standards and governance
• Oversee integration points (e.g. identity, CI/CD, tooling) and ensure issues are resolved effectively
• Identify and drive improvements in system performance, scalability, and maintainability
• Contribute to and enforce documentation, standards, and operational best practices
• Ensure systems meet audit, compliance, and governance requirements, with full traceability of changes

Essential

• Extensive experience administering and supporting Linux-based systems in complex technical or engineering environments
• Strong troubleshooting skills across operating systems, networking, storage, and application layers
• Proven experience diagnosing and resolving complex technical issues, including across mixed or distributed environments
• Proven experience handling major incidents and outages, including leading resolution and contributing to Root Cause Analysis (RCA)
• Strong experience with automation and scripting (e.g. Bash, Python, or similar)
• Strong experience with configuration management or infrastructure-as-code tools (e.g. Ansible, Terraform, Puppet, or similar)
• Experience working with configuration-as-code practices and Git-driven workflows
• Experience designing, implementing, or supporting CI/CD pipelines for configuration and operational processes
• Strong understanding of system interoperability across distributed environments
• Experience working within defined standards, governance frameworks, and controlled processes
• Strong communication skills and ability to work closely with engineering, platform, and infrastructure teams
• Experience mentoring or supporting the development of other engineers
• Ability to operate effectively across time zones in a distributed organisation
• Proven ability to operate independently, set direction, and deliver outcomes

Desirable

• Experience leading or coordinating incident response activities
• Experience working alongside DevOps, platform, or infrastructure engineering teams
• Experience with monitoring, observability, and logging systems
• Experience supporting AI/ML or high-performance computing environments
• Understanding of identity and access management concepts
• Experience building or scaling operational processes or support functions
• Experience administering and supporting Linux-based systems in a technical or engineering environment
