About Bunny.net

Some people accept the internet as it is. We see what it could be.

At bunny.net, we don’t wait for change. We make it happen. You won’t find layers of red tape or play-it-safe thinking here. You’ll find people who move quickly, take ownership, and push ideas all the way to the edge. Literally.

You’ll build things that solve actual problems, not add to them.

We’re not perfect, and we don’t pretend to be. But we’re always improving. We’re looking for people who want to do the same, who take pride in their work, and aren’t afraid to challenge what’s possible.

Because everyone deserves a better internet. And we’re here to help it hop faster.

What will you do?

• Design and build core features for our CDN platform, with a focus on performance, scalability, and reliability
• Write and maintain systems that process millions of requests per second with low latency and high availability
• Collaborate across teams to evolve our distributed content delivery infrastructure
• Fine-tune protocols, routing logic, and caching systems to deliver faster experiences at the edge
• Contribute to Bunny Shield, implementing WAF, DDoS mitigation, and bot detection capabilities in real time
• Work closely with network and security engineers to refine TLS/SSL, HTTPS, TCP, and proxy configurations
• Diagnose and solve complex problems in large-scale distributed systems and networking stacks

What will you bring?

• Experience building CDN, edge computing, or large-scale distributed systems
• Strong backend engineering skills, taking a system from design to deployment
• Strong programming skills in one or more backend languages such as .NET (C#), Java, or similar
• Familiarity with content delivery architectures and reverse proxy tuning
• A good understanding of HTTPS, TCP, DNS, TLS/SSL protocols, and reverse proxy technologies like Nginx
• Familiarity with WAF, DDoS mitigation, or security-minded engineering, or the curiosity to learn fast
• A track record of shipping reliable, scalable systems under real-world traffic and edge conditions
• Clear thinking around tradeoffs at scale: latency vs. throughput, caching vs. complexity, performance vs. resilience
• Excellent communication skills to share complex technical ideas asynchronously
• Willingness to learn, adapt, and contribute to a fast-evolving technical stack

Nice to have

• Passion for optimizing performance and security at the edge
• Hands-on experience or knowledge of WAF, DDoS mitigation, and bot detection technologies
• Solid knowledge of DNS standards and scalability challenges
