At Infinidat, a Lenovo company, we empower enterprises and service providers with cutting-edge storage platforms that redefine performance, reliability, and cyber resilience at scale. We're looking for a mid-level engineer to join the team building our S3-compatible object storage, purpose-built for the throughput and latency demands of AI — including GPUDirect Storage integration for direct data movement between storage and GPU memory. - Native filesystem-level code interfacing with our storage backend's C API, bridged into our Go services via CGO - Low-level file and metadata operations: file handles, attributes, locking, and concurrent access patterns typical of a production filesystem - Correctness-critical logic around partial failures and rollback — ensuring operations that fail partway through don't leave the system in an inconsistent state - Concurrency and locking correctness across operations that touch shared filesystem state - Debugging and root-causing issues using system traces and logs, tracing behavior across distributed components - Strong C++ fundamentals: memory management, pointers, structs, and comfort reasoning about low-level system behavior - Experience with systems-level programming — anything involving file I/O, networking, or OS-level APIs is relevant, even outside storage specifically - Some Go experience is a plus (our services are Go with CGO bindings into the C layer), but strong C++ instincts matter more than prior Go exposure - Comfort with concurrency: locks, race conditions, deadlock avoidance - Careful, methodical debugging habits — this system prioritizes correctness over speed of shipping, and bugs here can mean data loss - Ability to read and extend existing native code rather than always designing greenfield systems  About Infinidat Infinidat’s enterprise storage portfolio provides global Fortune 500 enterprises and service providers with best-in-class solutions for primary storage, next-generation data protection, disaster recovery, business continuity, and cyber resilience. Infinidat’s acclaimed InfuzeOS is the one of the most flexible and complete enterprise software-defined storage architectures in the industry. We recently announced powerful enhancements, an extensive expansion, and the dynamic evolution of our award-winning G4 enterprise cyber and AI storage solutions! Not only did[Infinidat win over 40 awards in 2025](https://www.infinidat.com/en/blog/infinidat-continues-its-award-winning-leadership-enterprise-storage-and-next-generation-data), but was named a[Gartner® Peer Insights™ Voice of the Customer Award for Primary Storage](https://www.infinidat.com/en/blog/2025-accomplishments-serve-launching-pad-infinidats-2026-momentum) for the 7th time!
