On-site in San Francisco, CA

Are you a security engineer with a genuine passion for proactive, offensive security, someone who hunts vulnerabilities before they become risks rather than waiting for a report to land? Do you have CTF wins and hands-on white-hat hacking experience to back that up?

This is an opportunity to join a fast-growing, profitable startup at the forefront of AI infrastructure, building the compliance and reliability layer that enterprise customers like Adobe, Netflix, and NASA depend on in production. They're profitable, with 8-figure ARR, and you'd be joining them with seed-level equity ahead of a Series A raise.

Backed by top-tier investors, the team has built the world's most widely used LLM Gateway, a unified platform that gives developers secure, scalable access to every major LLM provider. Now, they're looking for a Security Engineer to proactively protect the platform at both the application and CI/CD levels.

You'll own LiteLLM's security posture across application and supply chain domains, with a mandate to maintain zero critical or high vulnerabilities and neutralize attack vectors before they become problems, working across offensive security, CI/CD, and secure release processes.

If you're looking for a role where deep security ownership directly shapes how an open-source product used by enterprises around the world stays secure, whilst benefiting from strong equity in an already profitable company before they raise their Series A, this is an outstanding opportunity.

The Role

• Own application-level security and maintain zero critical or high vulnerabilities
• Proactively identify, assess, and remediate attack vectors across the platform
• Actively hunt vulnerabilities and ensure robust defenses
• Oversee CI/CD security with zero supply chain incidents
• Embed security throughout development and deployment cross-functionally
• Continuously adapt security practices to emerging threats

The Person

• Experience at a startup (Seed to Series D), comfortable wearing multiple hats
• Strong background in security engineering and hands-on offensive or white-hat hacking
• Demonstrated experience with application and CI/CD security
• Security-related projects on resume, GitHub, or similar
• Evidence of winning past CTFs
