AI Researcher — Inference Optimization
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for an AI Researcher — Inference Optimization based in Spain.
This role offers the opportunity to advance the performance of large-scale machine learning models through cutting-edge inference optimization research. You will work at the intersection of AI research, model architecture, systems engineering, and hardware-aware optimization.
Your work will directly influence latency, throughput, memory efficiency, and the cost of running sophisticated AI workloads. You will design and evaluate innovative optimization techniques and translate research findings into production-ready systems.
The role combines hands-on experimentation with close collaboration across research and engineering teams. You will benchmark inference workloads across modern hardware accelerators and identify opportunities for measurable performance gains. This is an impactful opportunity to help shape efficient, scalable AI infrastructure for real-world production environments.
Accountabilities:
- Research and develop advanced techniques to improve inference performance for large neural networks and machine learning models.
- Optimize key performance dimensions including latency, throughput, memory efficiency, and cost per inference.
- Design and evaluate model-level optimization techniques such as quantization, pruning, KV-cache optimization, and architecture-aware simplification.
- Implement systems-level optimizations including dynamic batching, kernel fusion, multi-GPU inference, and prefill versus decode optimization.
- Benchmark and profile inference workloads across different hardware accelerators to identify performance bottlenecks and optimization opportunities.
- Collaborate closely with engineering teams to integrate optimized inference techniques into scalable production pipelines.
- Translate research findings and experimental results into reliable, production-ready improvements.
- Establish clear benchmarks, document findings, and communicate results to inform technical and product decisions.
- Explore emerging approaches such as long-context inference, speculative decoding, KV-cache compression and paging, efficient decoding strategies, and hardware-aware inference design.
