Your Role As a Security Engineer , you will take ownership of protecting our product, our users, and our collaborators as we scale a fast-growing AI companionship platform. You'll work hands-on across application security, risk & compliance, and security awareness (plus keeping an eye on AI-specific threats as our product line evolves). Given the nature of our product (AI-generated content, including NSFW) you'll play a key role in keeping both our systems and our users safe, with real ownership from day one. This is a hands-on role reporting directly to the Security Lead, with regular check-ins on priorities. Key Responsibilities Application Security Perform weekly code reviews to catch vulnerabilities before they ship
Track, prioritize, and drive remediation of security vulnerabilities across the stack
Coordinate external security audits and penetration tests, and follow through on findings
Governance, Risk & Compliance (GRC) Maintain and evolve our risk register, mapping all company services and prioritizing what's exposed
Support audit follow-up and keep GRC documentation up to date
Security Awareness Communicate new threats to the team, document findings, and broadcast security updates company-wide
Run phishing simulations and security training (via Riot)
Monitoring & Coverage Own the monitoring of security channels and alerts, including weekend coverage, so nothing goes unanswered
IT & Access Management Set up and secure new employee devices (MDM), manage access provisioning/deprovisioning
AI Security Monitoring Keep an eye on emerging attack techniques targeting generative AI (prompt injection, jailbreaks, content filter bypass)
Track security incidents and vulnerabilities disclosed by the third-party AI providers we rely on
Your Qualifications Hard Skills Solid experience in application security (code review, vulnerability management)
Experience coordinating or conducting penetration tests / security audits
Comfortable shipping code and working with Git/GitHub workflows
Scripting/automation skills
Bonus: familiarity with AI/LLM security concepts (prompt injection, jailbreaking, adversarial testing) — this is still an emerging field, so curiosity matters more than proven experience
