Job description
We are looking for an experienced, hands-on Senior Cyber Security Engineer to take
technical ownership of our security tooling and controls the first dedicated cyber
security hire in a growing in house IT and Security function.
Reporting directly to the Head of IT & Security, this is a high autonomy role with a genuine voice in shaping our security
strategy: not executing someone else's playbook, but helping to write it.
You will own the configuration, hardening and continuous improvement of our defensive
stack across a modern Microsoft and Google estate, working hands on day to day while
partnering with the wider business to keep a fast-growing, global organisation secure and
resilient. As the function matures, there is a clear path for the right person to grow the role and, in time, a team around them.

- and policy optimisation of endpoint security tooling and enterprise mobile device
- management (MDM/MAM), namely Microsoft Intune and Defender.
- Identity & Access Management: Harden and manage Identity & Access Management
- (IAM) baselines across our core collaboration ecosystems (including Microsoft 365 and
- Google Workspace), ensuring strict adherence to the Principle of Least Privilege.
- Authentication & Email Hardening: Optimise modern authentication types (Windows
- Hello, macOS Platform SSO), secure application API permissions and Entra Enterprise
- App Registrations, and advance our email filtering policies ensuring our SPF, DKIM
- and DMARC records are correctly provisioned and optimal.
- Network Foundations: Support network security objectives, contributing technical

Incident Response & Vulnerability Execution
- Threat Mitigation: Act as the primary internal technical interface for our Managed
- Detection and Response (MDR) platform, coordinating rapid threat isolation, host
- containment and system tuning.
- Vulnerability Lifecycle: Deploy and manage vulnerability management tooling, taking
- ownership of patch remediation, configuration audits and threat tracking across the
- estate to systematically close technical blind spots.
- Resilience Planning: Assist in the design, technical testing and documentation of
- operational incident response playbooks and isolated system backup verification
- procedures.
- Continuous Tuning: Maintain and optimise anti-malware and filtering controls so that
- security standards balance effectively against user productivity.
Governance, Continuity & Collaboration
- Change Control: Adhere to and champion strict internal change control processes so
- that security enhancements and maintenance do not disrupt operational continuity.
- Security by Design: Partner with wider business units to conduct lightweight security
- and technical risk assessments on new third-party SaaS vendors and systems prior to
- onboarding.
- Compliance Telemetry: Support the Head of IT & Security with evidence gathering,
- audit tracking and data telemetry to validate our ongoing cyber resilience and
- company disclosure obligations.
- Security Culture: Promote a culture of accountability and security awareness,
- including the coordination and technical execution of data driven internal phishing
- simulation exercises.
Requirements
- Hands on experience administering and hardening the Microsoft stack Intune,
- Defender for Endpoint and Entra ID as the core of a live endpoint and identity estate.

- Privilege.
- A track record of operating independently in a security or senior infrastructure role,
