About the job
We are seeking an engineer to build security directly into our AI-native product, rather than auditing it externally. You will write production code, implement fixes, and possess a deep understanding of system architecture to identify and address vulnerabilities. Our platform operates AI-moderated video interviews at a massive scale, serving companies and soon, AI agents themselves. Security is paramount to earning the trust of our users as we integrate Listen into various tools and platforms.
Responsibilities
- Design and implement protections for sensitive data, including encryption, access boundaries, retention, and abuse resistance.
- Ensure multi-tenant isolation by maintaining boundaries between different user roles and studies.
- Threat model AI-native attack surfaces, including prompt injection, data exfiltration, and LLM-specific failure modes.
- Develop authentication, authorization, and API surfaces for programmatic and agentic callers.
- Build secure-by-default libraries, patterns, and CI/CD pipelines for security scanning.
- Conduct design and code reviews, and write production code to implement security fixes.
- Identify and address vulnerabilities in web and backend systems.
- Contribute to the development of secure API designs.
- Manage secrets and ensure supply chain hygiene.
Requirements
- Proficiency in a modern backend stack, with experience in TypeScript and Terraform.
- Ability to read, write, and review production code.
- Understanding of system design and failure modes, including OWASP Top 10.
- Knowledge of authentication and authorization mechanisms (OAuth/OIDC, sessions, RBAC).
- Familiarity with cloud and infrastructure security basics.
- Experience with secure API design and common vulnerability classes.
- Curiosity and willingness to learn about AI and LLM security.
- Strong problem-solving skills and ability to work independently.
- Excellent written communication skills for explaining complex ideas and risks.
Benefits
- Full medical, dental, and vision coverage
- FSA/HSA and life insurance
- Meaningful equity ownership
- Annual learning stipend for books, courses, conferences, etc.
