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:

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.

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.

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.

Strategic Security Projects (25–30%)

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

What You’ll Be Doing Day‑to‑Day

• Managing user access, SaaS tools, and device provisioning
• Monitoring security alerts, email authentication, and vulnerability reports
• Coordinating incident response and cross‑functional security escalations
• Maintaining compliance tooling and supporting external audits
• Overseeing MDM, endpoint protection, and zero‑trust network tooling
• Running security awareness and phishing simulation programmes
• Managing vendor risk assessments and tooling renewals
• Collaborating with People, Finance, Engineering, and leadership teams

Tools & Technologies You’ll Work With

(Experience with all is not required — but familiarity with similar platforms is ideal.)

• Identity & access management
• macOS/Windows MDM platforms
• Email security and endpoint protection
• Compliance automation tools
• SaaS procurement and licence management
• Cloud platforms and developer tooling
• Incident management systems
• Zero‑trust network access solutions

Who You’ll Work Closely With

You’ll partner with:

• Risk & compliance leadership
• Data protection and governance teams
• Engineering and platform security
• People/HR for onboarding/offboarding
• Finance for procurement and renewals
• All staff for IT support and security awareness

Who We’re Looking For

Someone who is:

• Confident owning both strategic security initiatives and hands‑on IT operations
• Comfortable context‑switching between long‑term projects and reactive support
• Experienced in modern SaaS environments and cloud‑first organisations
• Strong in stakeholder management and cross‑functional communication
• Passionate about building secure, scalable, user‑friendly systems
