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

Soft Skills

🗣 Strong communication & collaborative skills (perfectly fluent in English)

🧢 Goal-orientated, ownership and commitment

⚡️ Doer mindset - we are moving fast and we need people who can find the right balance between executing, planning and strategy

🧢 Humble - willing to learn, open to feedback

🍭 #NSFW - you are comfortable working in an environment with products that are based on uncensored models and content
