Job description

We are seeking a proactive and technically proficient individual to help architect, maintain, and optimise the core infrastructure that supports our mission-critical technology platforms. This individual will join a high-performing team tasked with designing and sustaining resilient, secure, and high-availability systems that meet rigorous uptime standards in a round-the-clock operational environment.

The ideal candidate is resourceful, detail-oriented, and thrives in a fast-paced, solutions-focused culture. You should be comfortable managing a wide range of responsibilities, from complex infrastructure design to hands-on troubleshooting, and be equally confident working independently or as part of a cross-functional team.

What You'll Be Doing

• Design, implement, and support technical infrastructure across compute, storage, network, and virtualization platforms.
• Maintain operational health and system performance across a hybrid on-prem and cloud environment.
• Conduct proactive capacity planning and performance tuning to prevent downtime and service degradation.
• Lead technical initiatives involving infrastructure upgrades, migrations, patching, and lifecycle management.
• Serve as a technical liaison to InfoSec, DevOps, and architecture teams to ensure system reliability, data integrity, and platform scalability.
• Manage and improve backup, disaster recovery, and business continuity strategies.
• Participate in on-call rotations to provide 24/7 support coverage for critical systems and services.
• Create and maintain detailed documentation, system diagrams, and operating procedures for internal and audit purposes.
• Support compliance and risk assessments in partnership with security stakeholders.

Skills & Requirements

• Minimum of 3 years' experience in systems engineering or infrastructure operations, preferably in mixed OS environments (Linux/Windows).
• Solid working knowledge of enterprise server technologies, including Active Directory, DNS, DHCP, Exchange, and related services.
• Strong scripting and automation skills (e.g., PowerShell, Bash, Python) to streamline operational workflows.
• Experience with server virtualization platforms, particularly VMware ESXi, vSphere, or similar hypervisors.
• Familiarity with SAN/NAS storage systems and storage protocols (iSCSI, NFS, SMB, etc.).
• Practical understanding of IP networking, Layer 2/3 protocols, VLANs, and site-to-site VPN configurations.
• Exposure to infrastructure-as-code tools and configuration management platforms (e.g., Ansible, Terraform).
• Comfortable navigating hybrid environments including cloud infrastructure providers such as AWS or Azure.
• Knowledge of endpoint protection, patching, and mail security best practices.
• Experience with enterprise-grade monitoring solutions and log analytics tools.

Advantageous

• Previous experience managing data center operations, migrations, or hybrid cloud integrations.
• Exposure to Microsoft 365 or Exchange Online environments.
• Familiarity with tools like Mimecast, Veeam, Rubrik, or similar technologies.
• Holds relevant industry certifications such as VCP, MSCA, AZ-104, or similar.

Who You Are

• Self-driven with a strong sense of accountability and ownership over deliverables.
• Able to juggle competing priorities and meet tight timelines without sacrificing quality.
• A collaborative communicator who thrives in multidisciplinary teams.
• Analytical and forward-thinking, with the ability to preempt issues and recommend scalable solutions.

This is a unique opportunity to work at the heart of a growing technology operation, where your expertise will directly influence system reliability, user experience, and technical innovation. If you're passionate about building and operating resilient systems at scale, we'd love to hear from you.
