IT Systems & Cybersecurity Lead

The IT Systems & Cybersecurity Lead is the company's single point of ownership for technology. You will keep our remote contractor laptop fleet and Microsoft 365 environment secure and running, act as technical owner of our ISO/IEC 27001:2022 certified information security management system, and maintain the internal web applications our operations, HR and account management teams use every day. This is a hands-on lead role in a small team: you will configure systems, review and write code and handle escalated support yourself, while setting direction and managing one IT/Cybersecurity Specialist. You will inherit a documented, working environment with a full handover.
