The role spans the full stack from low-level kernel optimization to distributed system tuning, requiring deep understanding of GPU architecture, model parallelism, memory management, and compiler-level optimization. The ideal candidate has demonstrated an impact on production of AI workloads, with strong instrumentation and measurement discipline that enables rigorous, data-driven optimization decisions. In this role you will work closely with cross-functional partners - product, design, engineering, operations, and business stakeholders - to translate ambiguous requirements into well-engineered solutions, and will be expected to raise the bar through code review, design review, and mentorship of more junior engineers. The successful candidate brings strong engineering discipline, a clear communication style, and a track record of shipping meaningful work that holds up well in production., * Profile and optimize end-to-end AI training and inference pipelines for throughput, latency, and cost. * Identify and eliminate bottlenecks across data loading, model compute, communication, and memory. * Implement and tune quantization, sparsity, and pruning strategies to reduce model footprint and accelerate inference. * Optimize distributed training using tensor parallelism, pipeline parallelism, FSDP, and ZeRO-style sharding. * Tune attention implementations using Flash Attention, paged attention, and related techniques. * Implement KV cache optimization, continuous batching, and speculative decoding for LLM serving. * Drive compiler-level optimizations using Triton, XLA, Torch Inductor, or TVM, working with the broader ML framework community to land improvements that translate into measurable end-to-end performance gains. * Optimize data pipelines, sharding strategies, and storage access patterns for high-throughput training. * Build and maintain rigorous benchmark suites and regression frameworks across workloads. * Collaborate with ML and platform engineering teams to embed best practices in standard pipelines. * Drive cost-efficiency improvements through model architecture, hardware selection, and scheduling strategies. * Evaluate new hardware and software offerings and advise on adoption. * Document performance tuning playbooks and share findings broadly across engineering teams. * Stay current with AI systems to research and translate advances into production improvements. ## Related Videos - [Efficient deployment and inference of GPU-accelerated LLMs​](https://www.wearedevelopers.com/videos/929-efficient-deployment-and-inference-of-gpu-accelerated-llms) - [Tour de Force: Open-Source LLM Inference Optimization from Simple to Sophisticated](https://www.wearedevelopers.com/videos/100099-tour-de-force-open-source-llm-inference-optimization-from-simple-to-sophisticated) - [Profiling Symfony & PHP apps with Blackfire](https://www.wearedevelopers.com/videos/265-profiling-symfony-php-apps-with-blackfire) - [Trends, Challenges and Best Practices for AI at the Edge](https://www.wearedevelopers.com/videos/630-trends-challenges-and-best-practices-for-ai-at-the-edge) - [AI Factories at Scale](https://www.wearedevelopers.com/videos/1139-ai-factories-at-scale) - [Enhancing Workload Security in Kubernetes](https://www.wearedevelopers.com/videos/356-enhancing-workload-security-in-kubernetes) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [What Are Large Language Models?](https://www.wearedevelopers.com/magazine/304-what-are-large-language-models) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [Got AI ideas but no money?
