Senior DevOps Engineer (WebRTC/LiveKit)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior DevOps Engineer (WebRTC/LiveKit) based in Brazil.

This role is centered on building and operating high-performance, real-time infrastructure that powers next-generation WebRTC and AI-driven applications. You will take ownership of scalable cloud environments, with a strong focus on LiveKit-based systems, ensuring reliable, low-latency communication services across global users. The environment is highly technical and collaborative, combining DevOps excellence with cutting-edge real-time media and AI agent infrastructure. You will be responsible for designing CI/CD pipelines, managing infrastructure as code, and ensuring observability across complex distributed systems. A key part of your work will involve optimizing performance, reliability, and security for real-time workloads in cloud-native environments. This is a hands-on senior role where your contributions directly impact system stability, scalability, and end-user experience. The team operates in a fully remote, fast-paced, and internationally distributed setup.

• Design, build, and scale cloud infrastructure to support real-time and WebRTC-based applications, including LiveKit environments.
• Deploy and manage WebRTC infrastructure components such as media servers, TURN/STUN servers, and real-time communication systems.
• Implement and maintain CI/CD pipelines, infrastructure as code (Terraform, Ansible), and automated deployment workflows.
• Ensure system observability through logging, monitoring, metrics, and alerting using tools such as Prometheus, Grafana, ELK, or Datadog.
• Manage containerized environments using Docker and Kubernetes, ensuring scalability and operational efficiency.
• Monitor system performance, reliability, and security, implementing proactive incident response and mitigation strategies.
• Collaborate with engineering teams to optimize build, deployment, and runtime processes for real-time applications.
• Maintain cloud infrastructure across AWS and other providers (Google Cloud or Azure), ensuring resilience and cost efficiency.
• Participate in agile ceremonies and client-facing updates, including standups and weekly demos.
