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.
Our CDN delivers millions of requests per second from 119+ PoPs worldwide, and we’re relentlessly tuning every layer to perform faster, smarter, and more efficiently at scale. As a Senior Software Engineer on our Content Delivery & Security team, you’ll work on the core products that power our CDN and authoritative DNS, while helping shape Bunny Shield: our edge security platform for WAF, DDoS mitigation, and bot management.
We’re looking for someone who thrives in a high-trust environment. Someone who takes initiative, enjoys figuring things out, and sees challenges as chances to build something better. You’ll join a small, fast-moving team of three that values ownership, autonomy, and thoughtful collaboration. You’ll have the space to lead your own ideas from start to finish, with teammates who jump in when it counts. It’s the kind of role where your code and your thinking directly shape how the internet performs.
What will you do?
- Build high-performance systems in C# (.NET) that power our CDN and security platform
- Build and evolve the core of Bunny Shield, shaping how CDN Security and DDoS Protection work at the edge
- Write and maintain distributed systems that handle millions of requests per second
- Tune caching, routing, and protocol logic for speed and efficiency
- Collaborate with network and security engineers to optimize TLS/SSL, HTTPS, and proxy layers
- Partner across teams, from infrastructure to product, to bring new features to life and make existing ones shine
- Take ownership of projects from design through deployment and continuously improve them over time
What will you bring?
- Deep C# (.NET) experience, or strong backend skills in Java or Go, with a genuine willingness to switch to .NET
- Curiosity about network security (WAF, DDoS, or bot mitigation), even if it’s new to you
- Familiarity with reverse proxies like Nginx or similar technologies
- Strong communication skills: you can explain complex ideas clearly and collaborate in an async, remote-first team
- A builder’s mindset: you take ownership, seek clarity, and aren’t afraid to figure things out independently
- A love for clean, performant code and a drive to constantly make systems better
What will make us extra happy?
- Hands-on experience or knowledge of WAF, DDoS mitigation, and bot detection technologies
- You’ve worked on CDN-like systems or performance-critical services before
- You’ve built or hosted side projects just because you had to know how it works, whether at work or on your own
- You love squeezing every bit of performance out of a system
- You enjoy pairing, sharing, and learning, because great engineering happens when ideas collide
