Researcher

Description:

Location: Tel Aviv/ Ra'anana

Job Summary

DriveNets is seeking a senior AI Researcher to join its R&D group and lead the frontier of large-scale LLM optimization. You will focus on maximizing performance, scalability, and efficiency of LLM training and inference across massive GPU clusters, bridging deep learning research, distributed systems design, and hardware-aware optimization.

At DriveNets, we treat AI performance as a systems problem. Just as we reinvented networking through disaggregation and software-defined scale, we’re applying the same philosophy to AI infrastructure. Your work will directly influence how large models are deployed, scaled, and optimized across high-density compute environments.

Key Responsibilities

● Conduct cutting-edge research in artificial intelligence and machine learning, from problem formulation to experimental validation.

● Research, design, implement and evaluate novel algorithms, models, optimization strategies and architectures across areas of large-scale LLM training and inference (e.g., tensor/pipeline/expert parallelisms, quantization, prefill/decode disaggregation, GPU communication optimization).

● Translate research ideas into working prototypes and production-ready solutions.

● Stay up to date with state-of-the-art research, frameworks, and emerging trends in the AI ecosystem.

● Publish research findings internally and externally (papers, technical reports, blog posts, or patents) and present results to internal and external technical audiences.

● Collaborate closely with engineers, product teams, and other researchers to align research with real- world impact

● Profile distributed training and inference pipelines - identifying algorithmic, memory, and scheduling inefficiencies to contribute to a technical decision-making and long-term research roadmaps.

● Validate research through measurable impact, higher throughput, better FLOPS utilization, improved convergence efficiency, or reduced compute cost.

● Strong foundation in machine learning, deep learning, and statistical modeling.

● Deep understanding of deep learning internals—transformer architectures, distributed training paradigms, precision scaling, and optimizer behavior.

● Proven hands-on experience training or deploying LLMs on multi-GPU and/or multi-node clusters.

● Ability to read, understand, and critically evaluate academic research papers. Demonstrated ability to translate theoretical ideas into practical, production-level performance improvements.

● Strong problem-solving skills and ability to work independently on open-ended research problems.

● Clear written and verbal communication skills in English.

Optional Qualifications

● MSc or PhD in Computer Science, Electrical Engineering, Mathematics or a related quantitative field.

● Strong mathematical background, including linear algebra, probability, and optimization.

● Strong grasp of parallel and distributed systems principles, including communication collectives, load balancing, and scaling bottlenecks.

● Proficiency with frameworks like DeepSpeed, Megatron-LM, NeMo VLLM, SGLang, or equivalent large- scale training ecosystems.

● Understanding of CUDA, Triton, or low-level GPU kernel development, and experience profiling large

models across multi-node GPU systems.
