Founded in Ukraine, scaling worldwide

About the role: We're building a greenfield high-load media platform from scratch, allowing you to shape the architecture, choose the technology stack, and make key engineering decisions from the very beginning. This isn't about maintaining legacy systems-it's about designing and delivering scalable solutions that will evolve from PoC into production

You'll tackle complex engineering challenges around WebRTC, low-latency streaming, SFU/TURN infrastructure, and scaling the platform to 300,000 concurrent connections and 3M+ requests per second. As part of a small, highly skilled team, you'll have real ownership, fast decision-making, and the chance to build rare, highly valued expertise while making a visible impact on the product

In this role, you will

• Design and build the infrastructure for a greenfield streaming/WebRTC platform, ensuring scalability, low latency, and high availability

• Develop and maintain CI/CD pipelines and deployment strategies to support fast and reliable releases

• Manage cloud infrastructure and Kubernetes clusters using Infrastructure as Code tools

• Implement autoscaling, performance optimization, and load testing to ensure the platform can handle high traffic and peak loads

• Build and improve the platform's observability by implementing monitoring, logging, tracing, and alerting solutions

• Optimize infrastructure for performance, reliability, security, and cost efficiency

• Collaborate closely with backend engineers and product teams, contributing to architectural decisions and the evolution of the platform

It’s all about you

• 3+ years of experience as a DevOps Engineer in production environments

• Experience designing and building high-load infrastructure from scratch

• Hands-on experience with streaming, WebRTC, or social/multimedia products

• Production experience with Kubernetes, including scaling, autoscaling, and troubleshooting

• Knowledge of observability tools, including Prometheus, Grafana, logging, and distributed tracing

• Strong networking fundamentals, including UDP, RTP/RTCP, low-latency networking, and TURN/STUN (coturn)

• Experience with load testing and performance optimization for high-traffic production systems

Would be a plus

• Experience with media servers, such as mediasoup, LiveKit, Janus, or Jitsi
• Experience optimizing bandwidth-heavy streaming platforms and improving infrastructure cost efficiency
• Proficiency in scripting with Python, Go, or Bash
