Content Delivery Network Engineer

At Sky Czech Republic, we're building the tech backbone that powers some of the world's biggest streaming services. Ever heard of Peacock in the U.S., Showmax in Africa, or Sky Showtime in the Czech Republic? They all run on our global streaming platform—a kind of technological skeleton where each service plugs in its own content and branding. Our platform serves millions of users worldwide. Just to give you an idea—Peacock alone has more than 40 million users in the U.S.

Thousands of engineers globally are shaping this platform, and our Prague tech hub is a key part of that effort. But we don't just keep the engine running—we push the tech boundaries of what's possible, alongside teams from Lisbon, London, and New York. Here in Prague, we have teams specializing in frontend development (including mobile, TV, and web), backend development (Java), DevOps & Platform Engineering, AWS, and data science.
