• Keep our AWS estate secure across IAM, network controls, encryption, logging, and workload protection, partnering with platform engineering on guardrails, Service Control Policies, and secure landing zones

• Manage our Cloudflare edge as a security control, tuning WAF rules, overseeing rate limiting and bot management, and responding quickly as threats evolve

• Lead detection and response for cloud and edge incidents, develop detections in our SIEM, and produce post‑incident reviews that help us learn and improve

• Develop and maintain our technical security standards across cloud, WAF, IAM, and logging, keeping us aligned with best practice and our regulatory obligations

• Champion security best practice across our engineering teams, helping squads build security in from the start

• Extensive experience as a Platform Security Engineer, with the ability to operate independently and influence how security is done across a technology organisation

• Hands‑on experience with AWS, Cloudflare, Tenable, and SIEM, with the depth to use these tools confidently day to day

• Proven experience working to frameworks including NIST CSF, ISO 27001, and Cyber Essentials Plus, with a practical understanding of what good compliance really looks like

• Familiarity with Cloud Security Maturity Frameworks and benchmarks such as CIS, and the ability to apply them to raise security standards in practice

• Experience leading or contributing to incident response, particularly for cloud and edge incidents such as credential stuffing, IAM compromise, and exposed assets

• Strong working knowledge of Cloudflare Enterprise, including WAF rule authoring, Bot Management, and log pipelines into SIEM

• A clear communication style and the ability to translate technical risk into plain language for non‑technical stakeholders

• A collaborative approach, a strong track record of delivering results, and a genuine interest in how AI and automation can improve security operations
