Platform Security Specialist
We are seeking a Platform Security Specialist to help protect the systems, services and infrastructure that support a modern digital environment. This is an opportunity to work across security engineering, cloud platforms and operational teams to strengthen security controls, reduce risk and enable the safe delivery of reliable technology services.
You will design, implement and maintain security measures across cloud and on-premises platforms, with a focus on identity and access management, network security, endpoint protection, vulnerability management and secure configuration. You will contribute to the development of security standards, patterns and reusable controls, ensuring that security is embedded throughout the platform lifecycle rather than applied retrospectively.
Key responsibilities will include monitoring platform activity, investigating security events, supporting incident response and coordinating remediation of identified vulnerabilities. You will carry out risk assessments, review technical designs, contribute to threat modelling and provide practical guidance to engineering and infrastructure colleagues. You will also help maintain security documentation, evidence compliance with relevant policies and standards, and support audits where required.
The successful candidate will have experience in platform, cloud or infrastructure security, together with a strong understanding of secure architecture and common attack techniques. You should be confident working with identity providers, privileged access management, firewalls, logging and monitoring tools, vulnerability scanners and security information and event management platforms. Familiarity with cloud security principles, infrastructure as code, automation and scripting languages such as Python or PowerShell would be advantageous.
Excellent communication and collaboration skills are essential, as you will work with technical and non-technical stakeholders to explain risk and agree proportionate solutions. You will be methodical, curious and comfortable managing competing priorities in a changing environment. Relevant professional certifications or demonstrable equivalent experience are welcomed.
This role offers the chance to influence security strategy, improve platform resilience and contribute to a culture of secure, continuous improvement.
