# ML Research Engineer, Performance Optimization

Your Impact at LILA Lila is building a platform where AI and automation co-evolve to accelerate scientific discovery Our AI Research team is looking to hire a ML Research Engineer to maximize iteration speed for mid- and post-training runs on 1T+ parameter LLMs using the latest NVIDIA chips. This involves not only maximizing GPU utilization on an individual training run but also making these optimizations maintainable, reusable, and adaptable so that the rest of the research team always knows how to confidently use the latest optimized stack. What You'll Be Building GPU compute performance: profiling, kernel development, long-context handling, memory footprint optimization GPU cluster performance: collective/MoE framework optimization, comm/compute overlap, RDMA/IB/EFA usage, P/D disaggregation Big data handling: manage mid-training scale data across storage, streaming, tokenization, and processing RL pipeline: optimize the async RL cycle, including environment/sandbox interfacing, long rollout handling, large token metadata (such as router replay), and weight sync Setting the performance standard: make sure optimized configurations are tested, accessible, and adaptable to research
