Security Engineer
, 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.
Application Security
Track, prioritize, and drive remediation of security vulnerabilities across the stack
Coordinate external security audits and penetration tests, and follow through on findings
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
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
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
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
Strong communication & collaborative skills (perfectly fluent in English)
Doer mindset - we are moving fast and we need people who can find the right balance between executing, planning and strategy
NSFW - you are comfortable working in an environment with products that are based on uncensored models and content
We consistently launch world-first AI applications — setting the pace, not following it
Integral Impact
: Top-tier user growth, real-world adoption, and cultural relevance
A senior team that's launched, scaled, and exited & IPO'd multiple scale ups — now fully focused on reshaping AI companionship
Elite Remote Team
: 100% remote and built to win — world-class talent from Tier 1 tech companies, with a culture of ownership, velocity, and radical creativity
Contract Type:
Fully remote. Monthly allowance of 100 USD for health insurance expenses & access to unlimited 1:1 sessions with psychologists and lifestyle experts through OpenUp (also available to up to three of your family members)
Co-Working Space Budget:
Learning Budget:
Laptop provided + monitor budget up to 250 USD + keyboard/mouse/mic/headphones budget up to 150 USD
