• Write high-quality, performant, and maintainable code in Go and Rust
• Participate in the on-call rotation, gaining firsthand experience operating Dropbox’s production storage systems
• Investigate and resolve complex production issues, performing root cause analysis and driving continuous reliability improvements
• Partner with cross-functional teams (Networking, Hardware, Capacity Planning) to deliver end-to-end reliable and cost-efficient storage solutions
• Take ownership of scoped projects and demonstrate growth toward leading larger, cross-team technical initiatives

Requirements:

• 9+ years of strong understanding of distributed systems principles, including replication, consistency, and fault tolerance
• Experience developing and debugging production services in C++, Go, or Rust
• Familiarity with distributed storage systems, file systems, or data infrastructure at scale
• Demonstrated ability to write efficient, reliable, and maintainable code in mission-critical environments
• Experience troubleshooting complex systems and participating in on-call or operational rotations
• Solid communication and collaboration skills, with the ability to work across infrastructure and product teams
• Eagerness to learn, grow, and contribute to multi-year infrastructure evolution initiatives
• Experience building and operating large-scale object storage or distributed storage systems (e.g. S3, Ceph, GFS/Colossus)
• Deep interest in systems performance, profiling, and low-level optimization
• Familiarity with replication protocols, erasure coding, and data placement algorithms
• Experience with production monitoring, observability, and incident response workflows
• Contributions to infrastructure projects, open-source systems, or developer tooling that improved reliability and performance
