Lead Software Engineer (Storage)

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.

Lead Software Engineer (Storage)

We’re here to build better internet infrastructure, and Bunny Storage is a core part of that mission.

As a Lead Software Engineer, you’ll spend your time working on the heart of Bunny Storage: designing, building, and improving the systems that power it. You’ll stay close to the code while helping guide the platform's growth and evolution.

This role is about building reliable systems and rethinking how storage works at a global scale to make it faster and simpler for developers.

If your first instinct is “How can this be better?” and your second is to start building, you’ll fit right in.

What will you do?

• Take ownership of designing and evolving the platform behind Bunny Storage to support long-term growth and performance

• Lead a small team of Engineers looking after our Object Storage platform and a high scale Elasticsearch metadata store

• Set and raise the bar for what low-latency, high-resilience storage means in practice, and ensure the system lives up to it

• Deliver critical components in C#, and tune Linux systems for real-world workloads

• Take ownership of architectural decisions and keep the system improving, even when the path isn’t obvious

• Set clear technical direction and align the team around shared standards

• Find and fix I/O and networking issues before they impact users

What will you bring?

You’ll bring a deep experience building storage and distributed systems, and a strong sense of ownership over the systems you work on, meaning:

• Deep technical expertise, ideally in C#, and the Linux internals that matter

• Strong understanding of storage systems: filesystems, caching, file I/O, and the edge cases in between

• Real expertise in durability engineering: erasure coding, replication, consistency models, repair, rebalancing, and the metadata layer that ties it all together

• Real-world experience with distributed systems and a calm head when they act up

• A builder’s mindset: you shape roadmaps, connect customer needs to technical reality, and move through ambiguity with clarity

• A bias for action: you prototype, ship, and lead by doing

• Experience using AI tools to move faster, without relying on them to do the thinking for you

• A steady, pragmatic demeanor overall, when things break, or priorities shift

What will make us extra happy?

• Deep knowledge of S3 (or having worked with MinIO, CEPH, etc.)

• Fluency in async systems and concurrency patterns (CompletableFutures, reactive streams)

• A performance mindset and knowing how to get the most from bare metal

• A track record of navigating complexity at scale and making the hard calls that keep systems moving

Where should you be located?

This job is fully remote from Europe (ideally CET or a close time zone). You’re still free to hop around the world and switch up your scenery whenever you want.
