About this role:
This isnât one of those roles where âsecurityâ means running scans or writing policies that gather dust. Weâre looking for a real engineerâsomeone who thinks like a builder and a breaker. Someone who gets deep into the stack, whether itâs an API endpoint, a container image, or a browser sandbox. You know how things are supposed to workâand what happens when they donât.While some security professionals lean toward policy, compliance, or audits (and we value that too), weâre 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. Itâs for someone whoâs ready to do it.
As a Security Engineer at LiveKit, you will:
- Own security across the stackâapplications, 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 threatsâthen put that knowledge into action.
About You
Youâll thrive in this role if:
- Youâre a hands-on engineer who understands security from first principles.
- 6+ years of experience as a software engineer with an interest in security engineering.
- Youâve led or heavily contributed to security engineering efforts across applications, infrastructure, or both.
- You can analyze systems for weaknessesâwhether theyâre in business logic, configuration, or code.
- Youâre experienced with threat modeling, secure coding practices, and vulnerability management.
- Youâve worked with CI/CD systems, cloud platforms (AWS, GCP, etc.), and containerized environments.
- You can translate security concerns into engineering action without being the ânoâ person.
- Youâre an excellent communicator and collaborator who can document and evangelize best practices.
- Youâve responded to real-world security incidents, led postmortems, or driven 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.
- You've built (or tried to build) something with LiveKit (we always love that!).
Our Commitments to You
We offer:
- A competitive salary and equity package.
- Health, dental, and vision benefits.
- Flexible vacations.
- A remote-friendly work environment, with equipment provided.
Compensation Range: $150K - $250K
