About the role
United Tech is a global IT product company shaping the future of real-time social connection. With millions of users across North America, Europe, LATAM, and MENA, we build next-gen mobile and web apps for live-streaming and social networking. Our platforms enable connection at scale fast, interactive, and deeply engaging. The market is projected to exceed $206B by 2030, and we are already leading the evolution. 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
