Job summary

LiteLLM is seeking a Senior Security Engineer to join as the first security hire. You’ll own security across application, infrastructure, and the software-delivery pipeline, working directly with engineers to embed secure development practices.

The role emphasizes hands-on security, thorough code reviews of Python components, threat modeling, incident response, and building tooling for SAST/DAST, SBOMs, and secure CI/CD workflows. You’ll shape LiteLLM’s security program from the ground up.

Qualifications

• Partner directly with engineers throughout design, implementation, code review, and release—not only after code is shipped.
• Build application-security tooling into the development lifecycle, including SAST, DAST, dependency scanning, and secrets detection.
• Perform internal red teaming and adversarial testing against LiteLLM’s APIs, proxy, and LLM-specific attack surfaces.
• Threat-model new products and architecture changes before they reach production.
