Our team consistently extends its capabilities to meet exact needs based on specific business requirements, with customers coming from a wide range of industry sectors.\nAt iNFINITUM, our success depends on our people, productivity, and procedures. We believe that the continuous success of our projects depends upon the outstanding performance of our highly skilled and trained staff. Providing access to modern professional training designed in line with real-world challenges is paramount to that success.\nWe are seeking a highly analytical and systems-oriented engineer with a strong desire to understand the foundational mechanics of IT infrastructure. The ideal candidate possesses a proven aptitude for troubleshooting, optimizing performance, and reverse-engineering system configurations. We prioritize strong technical fundamentals, intellectual curiosity, and the capability to transition hands-on technical skills into managing production-grade virtual environments, enterprise storage, and resilient systems, rather than strictly requiring extensive enterprise tenure.\nResponsibilities\nVirtual Infrastructure Management: Assist in the provisioning, configuration, and ongoing maintenance of virtual machines, compute resources, and hypervisors.\nStorage & Network Operations: Monitor SAN/NAS storage arrays, manage capacity planning, and support core network and VLAN configurations.\nSolution Evaluation & Validation: Critically review and validate scripts, configurations, and third-party technical solutions to ensure security, accuracy, and production readiness.\nIncident Management & Root Cause Analysis: Investigate system anomalies and failures, conduct thorough root cause analyses, and implement robust solutions to prevent recurrence.\nTesting & Quality Assurance: Develop and maintain staging environments and testing protocols to safely validate deployments prior to production rollout.\nDocumentation: Create and maintain comprehensive operational runbooks and audit trails for infrastructure procedures.\nRequirements\nAnalytical Aptitude: A demonstrated passion for system architecture, continuous optimization, and deep-level troubleshooting beyond standard GUI operations.\n Code & Solution Auditing:\nProficiency in analyzing and comprehending common system scripts (e.g., Bash, PowerShell, Python) to evaluate logic and execution flow.\nStrong risk-mitigation skills, including the ability to identify potentially destructive commands, unsafe privilege escalations, and unintended side effects prior to deployment.\nThe ability to accurately assess third-party or automated solutions for efficacy, stability, and security compliance.\nOperating System Fundamentals: Comprehensive understanding of Linux and/or Windows Server environments, including process management, permissions, file systems, mount points, and core services.\nNetworking Foundations: Strong grasp of fundamental networking concepts, including DNS, DHCP, subnetting, routing, gateways, and port management.\n Virtualization Knowledge: Working knowledge of hypervisor platforms (e.g., VMware, Proxmox, Hyper-V, KVM) and an understanding of the interaction between virtual disks, snapshots, virtual switches, and physical hardware.\nCommunication Skills: Professional proficiency in English, with the ability to clearly articulate technical issues, troubleshooting methodologies, and risk assessments.\nPreferred Qualifications\n Independent Technical Projects: Experience managing personal lab environments, self-hosted services, or independent infrastructure projects (e.g., personal servers, hypervisors, network appliances).\n Advanced Storage Knowledge: Familiarity with enterprise storage architectures (RAID, iSCSI, NFS) and comprehensive backup strategies.\nAdvanced Testing Environments: Practical experience utilizing sandboxes, disposable containers, or virtual machine snapshots for isolated environment testing.\nNote: While relevant industry certifications are advantageous, demonstrated hands-on experience and intellectual curiosity are highly prioritized.\nBenefits\nFriendly and Dynamic Working Environment. \nCompetitive Remuneration package directly dependent on the candidate's qualifications and experience. \nOpportunities for Continuous Learning of state-of-the-art technology and career development. \nPrivate Health and Medical Cover. \nWork-Life Balance initiatives. \nThe opportunity to work in a diverse environment with talented colleagues","description_format":"text","description_chars":4512,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Advanced
