About The Position

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.

Requirements

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

Nice To Haves

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

Responsibilities

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
