This is the company's first dedicated security engineering hire. You will report directly to the co-founder and CTO, define the security architecture, and build a practical security program for a platform that holds sensitive voice, face, and device data at significant scale. The role begins as a senior individual contributor position with the opportunity to build a team as the company grows.

What you'll do
• Define and build security architecture across the LLM pipeline, cloud infrastructure, and customer-facing product.
• Partner with engineering pods on threat modeling, vulnerability discovery, and secure design before features ship.
• Harden multi-tenant isolation and support multi-region data residency with the infrastructure team.
• Own penetration tests, vulnerability scans, remediation programs, and practical security policies.
• Manage internal device, access, identity, and security operations.
• Serve as the technical authority for audits, customer questionnaires, and enterprise security reviews.
• Build the roadmap for a durable security program that can scale with Fortune 500 customers.

Requirements
• 7+ years of security engineering experience.
• A software engineering or computer science foundation before moving into security.
• Strong application, infrastructure, and cloud security judgment.
• Demonstrated ability to find vulnerabilities in code and system designs, then work directly with engineers on practical remediation.
• Experience building or materially shaping a security program in a fast-moving technology company.
• Comfort operating independently while communicating clearly with technical leaders and enterprise customers.

Bonus points
• Experience as the first or founding security engineer at a high-growth startup.
• Familiarity with LLM security, sensitive research data, multi-tenant SaaS, or regional data-residency systems.
• Experience with TypeScript, identity and access management, penetration testing, or enterprise security reviews.
• Interest in growing from a senior individual contributor into a security leader who can build a team.

Benefits
• $230K-$300K base salary.
• Competitive equity.
• Visa transfers and new visa sponsorship may be available, including H-1B and TN cases.
• High-impact ownership as the founding security hire.

This role is on-site five days per week in San Francisco, California.
