Be CDN77’s support hero
We keep the world’s biggest websites running fast and smooth. Our teams take on real challenges. Join us whether you’re a total IT beginner or already know your way around the deeper stuff. All you need is:
Great written English
Interest in IT and technology
You’re up for working shiftsChoose your path
You’ll learn what a server, a switch, or routing actually is. Before long, you’ll be handling trickier technical challenges and network infrastructure problems too.
Our support solves real problems
Our infrastructure ranks among the global elite in digital content delivery – from worldwide VOD platforms to live streams of the UEFA Champions League. No broken printers. No please-restart-it. We tackle diverse challenges from the CDN world and work with technologies you’ll rarely encounter anywhere else in the Czech Republic.

- ~20% of the world’s internet population
- 1 global B2B product serving clients from 110+ countries
- 35,000 servers across 380 data centers
The alpha and omega of happy customers
We have a reputation as the best support on the market. Our only investor is a satisfied customer. We communicate in real time, often when stakes are high. The way we work builds trust that holds for years. Which is why customers send us hearts… and every now and then, a message saying someone on the team is, quite literally, a god.

The roles
Customer Care

We’re hiring both rookies and seasoned support pros. You might start with just great English, but within a year you’ll be deep in the world of network infrastructure. And if you’re already a pro, interesting advanced challenges are waiting for you, whether it’s a connectivity outage in Frankfurt or BYOIP requests via BGP.
- You’ll be there for customers over chat & email
- Answer questions about our product and service
- Learn a ton about running servers all over the world
- Get all the backing you need to grow in whatever direction you choose
Our team runs customer support 24/7/365. That means shift work, and sometimes a weekend or a night comes up. But don’t worry, we’ll take really good care of you.
Tech Support

This one’s a step up when it comes to technical know-how. In time, you could grow into a developer. Or a Linux admin, a network engineer… or wherever curiosity takes you. 😊
- You’ll troubleshoot and resolve issues – from basic HTTP checks to deeper log, video streaming, and network analysis
- Work with tools like Grafana, Postman, ffmpeg, and Unix-like systems (your daily bread)
- Dive deep into the world of CDNs, live & on-demand video streaming, web technologies, and more
- Blend your love for communication, critical thinking, and problem-solving
Not your typical “YouTube Tech Support” guy description, eh? Although they always solve everything (and so will you, in due time; just on a far bigger scale).
HW Technician

Sometimes our whole infrastructure rests on the people keeping L1 down on the ground humming. Gotham has its Batman, the Fellowship of the Ring has its Gandalf… and our physical servers have you.
- You’ll handle first-level technical support for our clients
- Work with servers, cabling, and the latest technology
- Keep the global infrastructure running alongside our team of Linux admins
- Now and then, get the chance to travel abroad
Just like in Tech Support, you’ll have room to move further over time. Drawn to ops or Linux? One of your predecessors now runs our entire CDN backend team; another oversees server installations in 50+ countries. Where will you want to be?
Culture that fits you
We work out of a handful of villas in Vinohrady. Sink into the garden during the day, or hang out with the team around the grill come evening. We’re not a corporation to tie you down with rules. Take a look at the one-of-a-kind setting where we push a successful global product forward :)
