Principal Security Engineer
FullTimeJob Overview
Join us in redefining the creator economy with AI
Fanvue is one of the fastest-growing creator monetisation platforms globally. We're an AI-powered, creator-first platform helping creators connect, engage, and earn directly from their audiences at scale. Following our recent Series A, Fanvue has surpassed $100M+ in annual recurring revenue, with triple-digit year-on-year growth, supporting hundreds of thousands of creators and millions of fans worldwide.
As Fanvue scales, security becomes one of the most critical functions in the company. This role exists to own and build our security posture from the ground up — across infrastructure, application, payments, and compliance — and help protect how hundreds of thousands of creators and millions of fans use Fanvue.
🎯 The Role
You will be the single-threaded owner of security at Fanvue. You'll design and implement controls across our AWS infrastructure, application layer, CI/CD pipelines, and payment flows. You'll drive SOC 2 Type II and PCI DSS compliance, build an incident response capability, and establish a security champion network across every engineering stream. This is a high-ownership, hands-on role where you shape how security works across the entire company. If you want to build a security function, not just inherit one, this is it.
🚀 What You'll Do
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
👀 Who You Are
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
