SRE (Linux, Firmware & Server Infrastructure)

Salary: £30,000 - 70,000 per year

Requirements

• We require strong Linux administration and troubleshooting expertise, including process and service management, system logs and diagnostics, networking fundamentals, and package/configuration management.
• We require a solid understanding of server hardware and infrastructure, including disks, RAID/HBA controllers, NICs, firmware interactions, and hardware failure modes with OS-level symptoms.
• We require proven experience with firmware management and upgrades, disk encryption, and secure server configurations.
• We require hands-on experience with remote management and lights-out technologies such as iDRAC, iLO, RACADM, Redfish, or similar APIs.
• We require a strong track record of incident ownership, including triage, mitigation, cross-team coordination, stakeholder communication, and driving issues through to resolution.
• We require experience working with vendor diagnostics, logs, support bundles, vendor escalation processes, and engineering engagement.
• We require excellent written and verbal communication skills, with the ability to explain technical issues to both technical and non-technical stakeholders.
• We require strong documentation skills, including creating runbooks, procedures, troubleshooting guides, knowledge base articles, and RCA reports.
• We prefer scripting and automation experience with Python, Bash, or Ansible.
• We prefer familiarity with configuration management and automation frameworks.
• We prefer exposure to virtualisation and containerisation technologies such as VMware, KVM, Docker, or Kubernetes.
• We prefer experience with monitoring, observability, alerting systems, log analysis, and alert tuning.
• We prefer understanding of SRE principles and metrics including SLOs, SLIs, error budgets, MTTR, and MTTD.
• We value a methodical, detail-oriented approach to troubleshooting, strong ownership, and the ability to work effectively in high-pressure, incident-driven environments.
• We require a collaborative mindset and the ability to work across global teams and vendors.
• We prefer candidates who are proactive about continuous improvement and operational excellence.

Responsibilities

• We own and manage end-to-end incident resolution for platform and hardware-related issues, including triage, mitigation, escalation, and post-incident review.
• We diagnose and troubleshoot Linux OS-level issues caused by hardware faults, firmware changes, or configuration inconsistencies.
• We manage firmware lifecycle processes, including upgrades, validation, and issue remediation.
• We work with disk encryption technologies and logging frameworks to ensure system integrity and auditability.
• We maintain and troubleshoot server configuration settings, including BIOS-level parameters across multiple hardware vendors, with a strong focus on Dell.
• We use out-of-band management tools such as iDRAC, iLO, RACADM, and Redfish APIs for remote diagnostics and recovery.
• We analyse vendor logs, support bundles, and telemetry data to identify root causes and remediation paths.
• We engage directly with hardware vendors and engineering teams, managing escalations and driving timely resolutions.
• We contribute to continuous improvement initiatives that reduce incident recurrence and operational toil.
• We produce and maintain high-quality documentation, including runbooks, troubleshooting guides, and knowledge base articles.
• We participate in post-incident reviews and support improvements in reliability metrics such as MTTR, MTTD, and SLOs.
