Senior IT Security Manager
We’re looking for an experienced Senior IT Security Manager to take ownership of IT security, compliance, infrastructure operations, and day‑to‑day IT support across a fast‑moving, modern SaaS environment.
If you thrive in a hands‑on, high‑impact role that blends strategic security leadership with practical operational delivery, this is an opportunity to shape and elevate the entire security posture of a growing organisation.
About the Role
This is a broad and influential position covering four key areas:
1️⃣ Reactive IT Support (20–25%)
You’ll lead the internal IT helpdesk function, ensuring smooth access management, device setup, SaaS administration, and onboarding/offboarding workflows. Expect a mix of predictable tasks and fast‑moving ad‑hoc support.
2️⃣ Security & Compliance (25–30%)
You’ll be the guardian of the organisation’s security posture — monitoring controls, managing audits, reviewing vulnerabilities, handling incident response, and driving continuous compliance across frameworks such as ISO27001 and Cyber Essentials.
3️⃣ Infrastructure & Operations (20–25%)
You’ll oversee the device fleet, MDM platforms, network and AV equipment, hardware lifecycle, and vendor relationships. This includes provisioning, policy enforcement, and ensuring operational resilience.

You’ll lead long‑term initiatives including security roadmap delivery, policy development, security awareness training, business continuity planning, and vendor risk management.
