Staff Security Engineer

This isn’t one of those roles where “security” means running scans or writing policies that gather dust. Someone who gets deep into the stack, whether it’s an API endpoint, a container image, or a browser sandbox. You know how things are supposed to work—and what happens when they don’t. While some security professionals lean toward policy, compliance, or audits (and we value that too), we’re after someone who wants to write code, secure systems, dig into strange bugs, and harden the platform from top to bottom. This is not a role for pointing out what needs to be done. As a Security Engineer at LiveKit, you will own security across the stack—applications, services, infrastructure, and developer workflows. Proactively identify, assess, and mitigate risks in both infrastructure and application codebases. Lead secure code reviews, architecture discussions, and threat modeling sessions. Build tooling and automations that help prevent security issues before they reach production. Harden authentication and access control across internal and external surfaces. Partner closely with engineers across teams to design secure-by-default APIs, workflows, and deployments. Investigate vulnerabilities, respond to security incidents, and manage disclosure processes when needed. Stay current with security research, tooling, and threats—then put that knowledge into action.
