• Automation & LLMs: Use tools and automation (including LLMs) to carry out common security operations tasks.
• Routine Security Testing: Introduce and embed tools to enhance Y TREE’s internal capabilities for routine security testing activities, and monitor/enhance security on CI/CD pipelines (SAST, DAST and SCA testing).
• Risk & Remediation Tracking: Maintain a register of security risks and remediations; work closely with Technology, Risk, and Compliance teams to track and close issues.
• Certifications & Policies: Support Y TREE’s efforts in maintaining current cyber security certifications and achieving higher accreditations, while maintaining/enhancing policies, documentation, and reporting on cyber metrics.
• Advocacy & Awareness: Elevate cyber security awareness across the organisation and champion best practices.
• External Audits: Collaborate with external cyber security consultants for external reviews, audits and assessments.

What You Bring

• Security Frameworks & Regulation: Experience with security-focused frameworks (e.g., CIS, NIST, ISO) and a track record of applying security controls in an FCA-regulated environment, with an understanding of key regulatory guidelines (e.g., GDPR, DORA).
• Threat Detection & Cloud Security: Experience with intrusion detection, prevention, and management (e.g., SIEM) alongside vulnerability management on cloud systems and applications (ideally AWS and Kubernetes).
• Incident & Penetration Expertise: Experience leading incident response and management, with familiarity in pen testing of applications and infrastructure.
• Application Security: Familiarity with OWASP principles, web application security, security practices on native mobile apps (iOS and Android), and security-by-design principles.
• Tooling & Threat Landscape: Familiarity with project management tools (Confluence, Jira, ServiceNow) and a good understanding of the threat landscape and risks from emerging technologies (like AI).
• Leadership & Growth: Comfortable taking the lead when required, eager to learn, and passionate about technology with a drive for continuous professional development.
• Mindset & Collaboration: An organised, meticulous, independent, and critical thinker who is an effective collaborator, open to feedback, and capable of identifying issues and building logical steps to overcome them.
• Communication Skills: Excellent written and verbal English skills, able to clearly articulate thoughts and ideas during interpersonal communication within our community.
