Stax, is representing an innovative technology company that is building a new generation of enterprise software. This company is focused on creating an intelligent, agent-based platform that enables businesses to operate more efficiently and connect more deeply with their customers.

We are seeking a highly skilled and motivated Senior Product Security Engineer to join a growing engineering team. In this critical role, you will be responsible for ensuring the security of the company's AI-native platform, protecting customer data, and building robust security into every stage of the product lifecycle. You will work at the intersection of cutting-edge AI technology and enterprise-grade security, helping to secure one of the most innovative platforms in the modern enterprise software landscape.

What You’ll Do

• Conduct security architecture reviews for new features, AI agents, and platform components.
• Develop custom correlation rules, dashboards, and automated alerts for threat detection.
• Establish security metrics and KPIs to measure the effectiveness of security controls.
• Manage the company's bug bounty program and coordinate with external security researchers.
• Lead vulnerability assessments and security testing of AI agents and machine learning pipelines.
• Conduct security risk assessments and develop comprehensive mitigation strategies.
• Address unique security challenges inherent in an agent-first platform architecture.
• Lead security incident response activities and coordinate with cross-functional teams.

What We’re Looking For

• A deep interest in product security, application security, or cybersecurity engineering.
• A strong understanding of security challenges specific to AI/ML, including model security, prompt injection, and data poisoning.
• Expertise in web application security, including knowledge of the OWASP Top 10 and secure coding practices.
• Fluency in Python and comfort working across full-stack and backend services.
• Experience building or using Large Language Models (LLMs), vector-based search, or agentic frameworks in production environments.

Why This Role Matters

As the company scales to become a backbone for customer-centric enterprises, you will be the guardian of the trust that makes its platform possible. You will protect sensitive customer conversations, proprietary product data, and business intelligence, ensuring that as the platform breaks down silos, it builds unbreakable security around the experiences that matter most.
