Note: The job is a remote job and is open to candidates in USA. LiveKit is building the infrastructure layer for the voice-driven era of computing. They are seeking a Staff Security Engineer to own security across the stack, proactively identify risks, and lead secure coding practices while collaborating with engineers to design secure systems.

Responsibilities

• 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

Skills

• 6+ years of experience as a software engineer with an interest in security engineering
• You've led or heavily contributed to security engineering efforts across applications, infrastructure, or both
• You can analyze systems for weaknesses—whether they're in business logic, configuration, or code
• You're experienced with threat modeling, secure coding practices, and vulnerability management
• You've worked with CI/CD systems, cloud platforms (AWS, GCP, etc.), and containerized environments
• 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
• You've responded to real-world security incidents, led postmortems, or driven remediation efforts
• Experience with security reviews of WebRTC, media pipelines, or real-time systems
• Contributions to open-source security tooling or research
• Hands-on experience with static and dynamic analysis tools, fuzzing, or sandboxing
• You've built (or tried to build) something with LiveKit
