Staff Security Engineer

Staff Security Engineer At LiveKit

This isn't one of those roles where "security" means running scans or writing policies that gather dust. We're looking for a real engineersomeone who thinks like a builder and a breaker. 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 workand 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. It's for someone who's ready to do it.

As A Security Engineer At LiveKit, You Will

• Own security across the stackapplications, 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 threatsthen put that knowledge into action.

• You can analyze systems for weaknesseswhether they're in business logic, configuration, or code.
• You're experienced with threat modeling, secure coding practices, and vulnerability management.

• You can translate security concerns into engineering action without being the "no" person.
• You're an excellent communicator and collaborator who can document and evangelize best practices.
