Job summary

Quantum is seeking a technical leader to drive the Centennial object storage team. You will balance hands-on coding with setting architectural direction across the data path, durability, S3, and data movement components.

You’ll design, implement, and optimize high-performance storage systems, mentor engineers, and collaborate with the engineering and product teams. A strong background in distributed systems and S3-compatible APIs is required, along with a willingness to work in our Centennial,

Qualifications

• 10+ years of software development using Go, Python, C, C++, or Rust (or equivalent systems-level expertise).
• Experience with distributed systems and high-performance storage software design.
• Strong Linux experience, including systems programming, debugging, profiling, and performance analysis.
• Solid understanding of concurrency, synchronization, locking, asynchronous programming, and memory management in performance-sensitive software.
