LiteLLM AI Gateway est un produit passerelle auto-hébergé et isolé qui centralise et contrôle l'accès aux grands modèles de langage, agents et plateformes de contrôle de modèles pour les équipes de plateforme. Il expose une API compatible OpenAI unique et un login unique (SSO) pour acheminer les requêtes vers plus de 140 fournisseurs et 1 800 modèles, gérer les clés et les gestionnaires de secrets, appliquer la gouvernance, observer et optimiser les coûts et l'utilisation, et permettre le changement de modèles de backend sans modifications de code. Le produit met l'accent sur des fonctionnalités d'entreprise telles que le contrôle d'accès, le routage, l'observabilité, les plafonds de coûts et le support dès le premier jour pour les nouveaux modèles, permettant aux organisations d'intégrer des modèles internes, ajustés et auto-hébergés derrière une clé unique.

Description

• Conduct deep security reviews of LiteLLM’s Python proxy, APIs, authentication systems, and enterprise features. • Identify and remediate vulnerabilities involving authentication, authorization, secrets, tenant isolation, injection, and data exposure. • 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. • Create secure coding guidelines and train engineers on common vulnerabilities and defensive practices. • Harden LiteLLM’s Docker images, PyPI packages, GitHub Actions workflows, and release infrastructure. • Detect dependency confusion, poisoned packages, compromised dependencies, exposed secrets, and unsafe build practices. • Implement SBOMs, signed builds, provenance checks, and reproducible-build practices. • Design secure-by-default configurations for cloud and self-hosted deployments, including authentication, IAM, secrets management, and key rotation. • Review cloud infrastructure, network boundaries, access controls, and production deployment patterns. • Strengthen employee identity, device, SaaS, and internal access controls. • Build monitoring and anomaly detection for suspicious API, model, authentication, and routing activity. • Lead security incident response, vulnerability assessment, remediation, post-mortems, and stakeholder communication. • Establish formal vulnerability intake, CVE triage, disclosure, and remediation processes. • Maintain threat models as LiteLLM’s product and architecture evolve.

🎯 Exigences

• A strong security generalist who can work across application security, IT, CI/CD, cloud infrastructure, and the software supply chain. • Deep application-security expertise, including manually auditing production Python code and working with engineers to remediate vulnerabilities. • Strong understanding of authentication, authorization, tenant isolation, SSRF, injection, deserialization, secrets management, and common web and API vulnerabilities. • Experience using and configuring tools such as Semgrep, Bandit, CodeQL, Burp Suite, and other SAST or DAST tooling. • Previous experience at an early-stage security startup during its 0→1 journey. • Experience securing containers, GitHub Actions, build pipelines, packages, and software dependencies. • Familiarity with SBOMs, Sigstore, Cosign, Snyk, Grype, Trivy, or equivalent tooling. • Strong knowledge of OAuth2, JWT, mTLS, IAM, and high-throughput API authentication. • Familiarity with prompt injection, LLM data exfiltration, tool abuse, and the OWASP Top 10 for LLM Applications. • Experience with incident response, CVSS scoring, vulnerability management, CVE triage, and coordinated disclosure. • Experience competing in CTFs during college or independently pursuing vulnerability research, reverse engineering, bug bounties, or security projects. • A genuine interest in security outside your day job—you regularly explore new attack techniques, build security projects, or contribute to the security community. • Bachelor’s or Master’s degree in Computer Science or a related field, or equivalent practical experience.

🏖️ Avantages

• Competitive salary and health, dental, and vision benefits
