Requirements
• A senior security engineer with 8+ years of experience, including 3+ years as the solo or founding security hire at a scaling company • Deep AWS security expertise: IAM, GuardDuty, Security Hub, VPC design, service control policies, and multi-account strategy • Strong application security fundamentals: OWASP, OAuth/OIDC, API authorisation, cryptography, and secrets management • Hands-on compliance experience — SOC 2, PCI DSS Level 1, GDPR and data residency • Proficient in TypeScript; can read and review application code for vulnerabilities • A track record of writing clear technical documentation — HLDs, RFCs, and runbooks that others can actually follow • Comfortable with infrastructure as code (CDK/Terraform), CI/CD security, and container scanning • Experience building a security champion programme and influencing cross-functionally without formal authority • ✨ You'll Thrive Here If • You want to build the security function from scratch, not maintain someone else's • You are energised by breadth — infrastructure, application, compliance, and culture all in one role • You are hands-on first: you write code, review PRs, and get into the detail before delegating • You communicate security risk in business terms, not just technical ones • You are excited by the pace and ambiguity of a high-growth startup • ⚠️ You'll Struggle Here If • You prefer to work within an established security team with defined scope • You are more comfortable writing policies than implementing controls • You need everything documented before you can act • You treat compliance as a checkbox exercise rather than a genuine risk reduction effort
Responsibilities
• Design and implement security controls across AWS infrastructure, application layer, CI/CD pipelines, and payment flows • Write RFCs/ADRs for security architecture decisions; maintain the security chapter in the engineering-rfcs-and-adrs repo • Establish and run a security champion network across Platform, Growth, AI, Creator Earnings, and other engineering streams, including weekly security office hours • Own the SOC 2 Type II and PCI DSS roadmap and execution — manage auditor relationships, evidence collection, and remediation tracking • Conduct threat modelling for new features including iframe patterns, AI Creator Studio integrations, and live streaming surfaces • Perform hands-on security reviews: IAM policies, secrets management, API authorisation, data encryption, and vendor contracts • Build incident response playbooks and run quarterly tabletop exercises with the on-call rotation • Partner with Legal on compliance across PCI DSS, GDPR, age verification, and content moderation policy • Configure and tune SIEM, vulnerability scanning, and dependency checks — own alerting and response • Review PRs for security-critical changes and embed security gates into the project checklist
Benefits
• Ownership from day one • Fast-moving team with real autonomy • Direct line of sight to outcomes and visible impact • AI-native working environment • Access to gyms, studios, wellbeing partners, and premium wellbeing apps • Recognised in the Sunday Times Best Places to Work • Winner of an International Business award for fastest-growing company • ⭐ Fanvue is for Everyone • We believe diverse teams build better products, and if you are excited by the role but do not tick every box, we still encourage you to apply.
