Lead the technical direction and hands-on development of an exabyte-scale object storage platform. Design and optimize data paths, S3 APIs, durability, erasure coding, data placement, fault tolerance, and movement across NVMe, HDD, and tape. Responsibilities include systems programming, Linux profiling, performance optimization, architecture, code reviews, testing, mentoring engineers, and collaboration on product scope and delivery.
Key Responsibilities - Technical Leadership
- Act as the technical lead for the Centennial object storage team while remaining substantially hands-on.
- Lead technical direction and drive key architectural decisions across the team's areas of ownership, including the data path, durability, S3, and data movement.
- Design and build critical components, lead design and code reviews, help engineers solve complex systems problems, and ensure appropriate automated testing and CI coverage for critical changes.
- Mentor engineers and develop technical ownership across the team.
- Partner with the Software Engineering Manager / Product Owner on scope, sequencing, technical risk, and delivery.
Object Storage Data Path & S3
- Design, implement, and optimize features in the ActiveScale data path, handling the flow from incoming S3 requests to durable storage across NVMe, HDD, and tape.
- Implement and extend the S3 API, ensuring correct protocol behavior and efficient request handling.
- Improve latency, throughput, scalability, and reliability of the I/O pipeline for exabyte-scale deployments using Linux profiling and systems debugging.
Durability, Data Placement & Resilience
- Own complex durability and data-placement work, including two-dimensional erasure coding, and ensure correctness under failures such as node loss, disk faults, partial writes, and network partitions.
- Analyze and optimize concurrency, throughput, and fault tolerance across the request and storage paths.
Scalability & Data Movement
- Design and improve systems that move and tier data from high-performance NVMe through HDD to the tape cold-storage tier (ActiveScale Cold Storage).
- Drive the evolution of internal APIs, services, and interfaces that support the data path and data mover.
Required Qualifications
- 10+ years of software development experience using Go, Python, C, C++, or Rust (or equivalent systems-level expertise), with a willingness to learn additional languages.
- Strong experience with distributed systems and high-performance storage software design.
- Strong Linux experience, including systems programming, debugging, profiling, and performance analysis of complex systems.
- Solid understanding of concurrency, synchronization, locking, asynchronous programming, and memory management in performance-sensitive software.
- Understanding of cloud and enterprise storage concepts and the characteristics of storage media such as HDD, SSD, NVMe, and tape.
- Experience with object storage or S3-compatible APIs.
- Demonstrated technical leadership of a team or significant engineering workstream.
- Strong communication skills and ability to collaborate across teams, including collaboration with the established ActiveScale engineering teams in Belgium.
- This is a hybrid role, with in-office work at our Centennial, CO office Tuesday through Thursday.
Preferred / Nice-to-Have Skills
- Experience with the Linux I/O subsystem and networking.
- Knowledge of erasure coding principles.
- Experience with storage protocols and clustering design and development.
- Experience with REST, gRPC, or Thrift.
- Experience with Amazon S3 APIs, SDKs, and tools.
- Familiarity with OCaml is welcome but not required; parts of the existing ActiveScale codebase are written in it.
