Job Description

Dropbox is a Virtual First company. For this role, we are currently only authorized to hire candidates from the following provinces: Alberta, British Columbia, Ontario, and Saskatchewan.
Role Description
As a Senior Software Engineer on the Storage team, you will help design, build, and operate Dropbox's large-scale storage systems that provide high durability and scalability for millions of users across all of Dropbox products. The Storage team owns the distributed storage infrastructure at the heart of Dropbox, systems responsible for storing exabytes of user data across multiple data centers worldwide.
You'll collaborate with experienced engineers across infrastructure and product teams to improve reliability, optimize performance, and evolve the architecture of Dropbox's storage layer. This role offers deep exposure to distributed systems and storage challenges such as replication, erasure coding, consistency tradeoffs, and performance tuning at massive scale.
It's an ideal opportunity for engineers who love building resilient infrastructure, learning from complex production systems, and growing into technical leadership. You'll gain hands-on experience operating mission-critical services, influence architectural decisions, and directly improve how Dropbox keeps user data safe, durable, and available.
