Security Engineer, Infrastructure Security

About the Role

ABOUT LIVEKIT LiveKit is building the infrastructure layer for the voice-driven era of computing. Our platform gives developers everything they need to build, test, deploy, scale, and observe agents in production. Founded in 2021, LiveKit powers voice AI applications for OpenAI, xAI, Salesforce, Coursera, Spotify, and thousands of others, collectively facilitating billions of calls each year. ABOUT THIS ROLE Our customers trust us with audio, video and data belonging to their own end users, so a security failure on our side puts their data and their business at risk. We are hiring an Infrastructure Security Engineer to improve the security posture of the production platform that carries that data. You will join a small Trust team that covers security, IT and compliance, and you will own real parts of the program from your first week. You will build our understanding of infrastructure security posture, then prioritize and drive remediation by business impact. Where the same class of problem keeps coming back, you will build the guardrails and security building blocks that let our security scale with the business. YOU'LL THRIVE AT LIVEKIT IF YOU - think like both a builder and a breaker, and understand security from first principles - take an automation-first and pragmatic approach to risk mitigation - translate security concerns into engineering action - can clearly explain complex technical concepts to others - are a fast learner and thrive in ambiguity WHAT YOU’LL DO - Map the security posture of our cloud and production infrastructure and turn it into a documented baseline. - Find the gaps that could lead to customer data loss or infrastructure compromise, agree a prioritized security debt backlog with engineering, and close the highest-risk items first. - Harden identity, secrets and network boundaries, including cloud IAM, environment separation and credential hygiene. - Secure the infrastructure that runs customer-deployed voice AI agents
