Grab the opportunity to immerse yourself in an environment where our developers, product team and client facing project teams work with state of the art parametric tooling, skill building, and integral functional design.

This role reports to the Head of Technology and is a key player in the IT operations of OMRT. You will make sure that every employee of OMRT is able to perform their daily work from a technology perspective, enabling us to deliver the results that our clients are accustomed to. You will be part of a small to mid-sized company where you can navigate increasingly complex projects and collaborate with various teams seamlessly, making a significant impact in our industry and for our clients.

What you’ll do

Capacity Planning: Proactively assessing future growth needs and planning for scalable infrastructure (servers, storage, network bandwidth) to accommodate increased user load, data volume, and application demands. 

Automation and Scripting: Implementing robust automation tools and scripting (e.g., PowerShell, Bash, Ansible, Terraform) to streamline deployments, configurations, monitoring, and routine maintenance tasks. 

Networking Essentials: Working with core networking concepts (TCP/IP, DNS, DHCP, routing, firewalls), including Ubiquiti Unifi networking hardware (e.g., access points, switches, routers).

Virtualisation and Containerisation: Extensive use and management of virtualisation (VMware, Hyper-V, Portainer, Proxmox) and containerisation technologies (Docker, Kubernetes) to maximize resource utilisation, ensure application portability, and facilitate rapid deployment.

Identity and Access Management (IAM): Implementing robust IAM solutions to manage user accounts, permissions, and access controls across systems. This often involves single sign-on (SSO) and multi-factor authentication (MFA). Proficient in administering and managing Google Workspace (formerly G Suite) for organisational collaboration and productivity.

Compliance Adherence: Ensuring that the IT infrastructure complies with relevant industry regulations, data privacy laws (e.g., GDPR), and internal security policies, which become more critical as the company grows and handles more data.

Proactive Monitoring and Alerting: Deploying sophisticated monitoring tools to track system performance, network health, application responsiveness, and resource utilization in real-time.
