About us
Think global, move fast, and make every millisecond count - that’s the CDN77 way.
We’re a Content Delivery Network (CDN) company, and we’ve been providing critical internet infrastructure for some of the world’s most trafficked websites, apps and live events for over 14 years. Our network is massive: 255 Tbps global capacity, with over a hundred Points of Presence across 130+ countries - built for speed, not show.
Who uses our services? Udemy, ESL Gaming, European Space Agency, Factorio, just to name a few. We are firm believers that the best investor is a happy customer. And to make every customer truly happy at our current growth rate, we need sharp, curious people on our Tech Support Team.
Your mission at CDN77
- Be the first line of contact for our customers - answer technical questions via chat, ticketing, and other dedicated channels.
- Troubleshoot and resolve issues - from basic HTTP checks to deeper log, video streaming, and network analysis, including escalations when needed.
- Become familiar with technical concepts and grow your knowledge of CDN, live & on-demand video streaming, networking and web technologies.
- Work closely with internal teams (tech & business) to translate customer needs into real solutions.
- Tinker with new processes, new features and continuous service improvements.
Expect learning on the fly, critical thinking, and figuring out solutions for clients without any handholding.
What tools will you be working with
- Unix-like systems (CLI) – your daily bread here: checking connectivity, running traceroutes, writing simple scripts, and analyzing network traffic
- Kibana & Grafana - for digging into logs, error codes, and performance metrics
- Postman - for testing and troubleshooting APIs
- ffmpeg – for real-time debugging and getting a new perspective on how Netflix-style video actually streams behind the scenes
- … and plenty more as you grow with us
You will be a fit if you are...
- Based in Prague and excited to work on-site with the team. Possibility to work partially remote after training.
- Proficient in written and spoken English, and you can explain complex matters in a clear and structured way (Czech is a plus, not required).
- Have basic technical foundation (computer science, hardware, HTTP, DNS, networking etc.)
- Naturally curious problem-solver - you just don’t stop at “it’s resolved”, you want to know the root cause
- Team player and customer-oriented - enjoy working with people from different backgrounds
- Ready to work on night shifts - after an initial period of shadowing, you'll gradually rotate through day/evening/weekend shifts, and once confident, fully transition to nights.
If this sounds like you, let’s chat. If not, no worries - this is a technical role, and we’re looking for people who are genuinely interested in, and want to grow in tech.
What we can offer you
- Fair financial compensation based on experience, performance and expectations
- Free food every shift (breakfast, lunch/dinner, fruits, snacks, lemonades, coffee, etc.)
- Flexible scheduling - it's not a problem to schedule your shifts around your plans or occasionally work remotely once you’re confident
- Opportunities for growth within the company
- Great working environment in our Vinohrady villas (and pet-friendly)
- Equipment of your choice (laptop, monitors, headphones, etc.)
- Ergonomic setup: Spinalis chairs and an adjustable standing desk
- Company barber
Our selection process
From start to finish, your contacts will be Travis and Jan, your future team leaders. We’ll start with a brief introductory call. If the vibe is right, we’ll invite you to our villa in Vinohrady to meet us and the VP of Client Solutions. After that, you’ll get a homework assignment to test your technical knowledge, communication and problem-solving skills. And if all goes well, the last step is a final meeting with our CEO, Zdeněk. We keep the process lean and personal - no HR involved, just the people you’ll be working with.
What can you expect if you're accepted
First, your team leaders will introduce you to your team and show you around the firm so that you gain a general overview of our team, product, company structure and business model.
We actively encourage personal and professional growth and, if it suits you, would love to see you move into higher, tech-heavy roles with us in the future. To give you an idea, some of our support staff have moved into roles such as a Technical Solution Architect, Linux Admin, Software Engineer, Network Engineer and CEPH Engineer.
