Founding Security Engineer (Detection, Incident Response, and SOC 2 Compliance)

About The Role

This is a founding security role at an early-stage AI/ML infrastructure company, giving you full ownership to build the security program from the ground up.

What You'll Do

• Lead detection and incident response end-to-end, from signal and alert through investigation, postmortem, and durable engineering improvements.
• Own the security roadmap spanning product security, cloud infrastructure, corporate security, incident response, and compliance.
• Secure APIs, platforms, and data systems through threat modeling, design and code reviews, authentication and authorization controls, and secrets management.
• Build and operate monitoring, detection, and incident-response capabilities, and turn emerging threats into lasting improvements.
• Own SOC 2 compliance and customer trust, including control design, security questionnaires, policy management, vendor reviews, and audits.
