• Proven track record of designing, building, and deploying large‑scale, high‑performance systems in production environments.
• Deep understanding of operating system concepts, networking stacks, and storage subsystems, particularly within Linux environments.
• Hands‑on experience with C++ (C++11/14/17) and low‑level programming, including device drivers and kernel modules.
• Demonstrated ability to lead complex projects, manage timelines, and communicate technical decisions to both technical and non‑technical stakeholders.

Preferred Qualifications

• Advanced degree (M.S. or Ph.D.) in Computer Science, Computer Engineering, or a related discipline.
• Experience with Remote Direct Memory Access (RDMA), InfiniBand, or other high‑speed interconnect technologies.
• Familiarity with HPC communication libraries such as MPI, OpenMPI, or MPICH, and with ML communication frameworks like NCCL.
• Background in cloud platforms (arenaflex Cloud, AWS, Azure) and container orchestration (Kubernetes, Docker).
• Knowledge of performance profiling tools (perf, VTune, Nsight) and techniques for latency reduction and throughput maximization.
• Contributions to open‑source projects or publications in top‑tier conferences/journals related to distributed systems, HPC, or AI.

Core Skills & Competencies

• Technical Excellence: Mastery of C/C++ programming, systems architecture, and performance optimization.
• Problem Solving: Ability to dissect complex problems, devise innovative solutions, and iterate rapidly.
• Collaboration: Strong communication skills, comfortable working with global, cross‑functional teams.
• Leadership: Experience guiding technical direction, mentoring peers, and influencing product strategy.
