C++ Developer

A premier, fast-growing Israeli AI Data Infrastructure and high-performance storage scale-up engineering next-generation object storage platforms purpose-built for massive AI and deep learning workloads.

The company’s architecture is tailored to meet the extreme throughput and ultra-low latency demands of modern AI clusters, eliminating data bottlenecks in high-scale distributed environments.

The engineering culture operates at the foundational systems layer, tackling complex low-level filesystem challenges, concurrent distributed access, and rigorous data consistency guarantees where system reliability is paramount.

Located in the Sharon region, operating on a hybrid model with two days working from home.

Role Description-

• Serving as a Senior Low-Level C++ / Systems Software Engineer, joining the core engineering team building high-performance object storage solutions optimized for demanding AI workloads.
• Developing critical filesystem-level logic interfacing directly with underlying storage APIs and integrating with Go-based services via CGO.
• Architecting and manipulating low-level file structures and metadata operations, including file handles, extended attributes, complex locking primitives, and high-concurrency access patterns in production environments.
• Designing fault-tolerant mechanisms to ensure strict data consistency, including partial-failure mitigation, rollback procedures, and atomic transactions.
• Ensuring correctness and thread safety across concurrency models, synchronization primitives, and shared filesystem resources.
• Diagnosing, tracing, and resolving distributed race conditions, bottlenecks, and anomalies across systems using deep OS-level tracing, memory profiling, and distributed logs.
• Reading, maintaining, and extending existing high-performance native codebases with an uncompromising focus on stability and preventing data loss.

Requirements-

• In-depth mastery of Modern C++, including manual memory management, pointer arithmetic, data structures, and low-level system mechanics – Mandatory
• Proven background in Systems-Level Programming, including practical experience with File I/O, Network socket programming, or OS-level APIs (prior storage experience is not required) – Mandatory
• Strong understanding and practical experience with multithreading and concurrency, including locks, mutexes, race conditions, and deadlock avoidance – Mandatory
• Methodical, detail-oriented debugging and troubleshooting capabilities with deep focus on software correctness and data reliability – Mandatory
• Demonstrated ability to read, comprehend, refactor, and scale large existing native codebases – Mandatory
• Strong technical communication, documentation, and problem-solving skills in English (written and verbal) – Mandatory
