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
