Software Engineer - Storage

About Supabase Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. About the Role Supabase Storage is a scalable and high performance object storage service and is one of our fastest growing services. The current landscape of tools for uploading, storing, processing and delivering assets is complicated. Developers are forced to think about regions, caching, codecs and security before they can start uploading anything. We are looking for engineers to solve this problem once and for all! You will be working across the entire stack - client libraries, CLI, CDN, the storage server and the deployment infrastructure. One day, you might focus on improving upload resilience in iOS applications; the next, you could be optimizing the S3 protocol for efficient retries or finding ways to accelerate upload processing. You will be contributing to both our open source server and upstream dependencies we use, like the TUS server . This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions.
