About LiveKit LiveKit is revolutionizing the AI landscape by providing essential network infrastructure that powers multimodal AI interfaces, enabling seamless audio and visual interactions. Founded in 2021, LiveKit supports over 3 billion calls annually, 100,000+ developers worldwide, and industry giants such as OpenAI, Character AI, Spotify, and Meta. Ideal Candidate Obsessed with crafting fast, reliable code. Known as the go-to person for tackling tough technical problems. Works hard, builds and ships quickly. Explains complex technical concepts clearly. Fast learner, frequently picking up new languages and tools. About this role This is not a policy‑focused security role. We want a real engineer who thinks like both a builder and a breaker, who digs deep into the stack, secures systems, and hardens the platform from top to bottom. Responsibilities Own security across the stack—applications, services, infrastructure, and developer workflows. Proactively identify, assess, and mitigate risks in infrastructure and application codebases. Lead secure code reviews, architecture discussions, and threat modeling sessions. Build tooling and automations to prevent security issues before production. Harden authentication and access control across internal and external surfaces. Partner with engineers across teams to design secure‑by‑default APIs, workflows, and deployments. Investigate vulnerabilities, respond to security incidents, and manage disclosure processes. Stay current with security research, tooling, and threats, and apply that knowledge. Qualifications Hands‑on engineer who understands security from first principles. 6+ years of software engineering experience with a focus on security engineering. Led or heavily contributed to security engineering efforts across applications, infrastructure, or both. Can analyze systems for weaknesses in business logic, configuration, or code. Experienced with threat modeling, secure coding practices, and vulnerability management. Worked with CI/CD systems, cloud platforms (AWS, GCP, etc.), and containerized environments. Translates security concerns into engineering action without being a gatekeeper. Excellent communicator and collaborator capable of documenting and evangelizing best practices. Responded to real‑world security incidents, led postmortems, or drove remediation efforts. Bonus Points 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. Built (or attempted to build) something with LiveKit. Commitments to You A competitive salary and equity package. Health, dental, and vision benefits. Flexible vacation policy. Remote‑friendly work environment, with equipment provided.
