Member of Technical Staff

AI performance is the major tech theme for the next decade. We are building systems that autonomously discover, test, and ship state-of-the-art GPU kernels. Our mission is to fully automate this process by combining LLMs with evolutionary methods. We just closed an unannounced $4.2M pre-seed round from top-tier funds and technical angels, and have proven results with large and sophisticated enterprise partners on custom neural architectures.We believe that revolutionary breakthroughs often happen at the intersections of fields. We are not a research lab, nor are we an AI agents company. We’re working at the intersection of LLMs and evolutionary computing to build self-improving systems. We’re looking for exceptionally talented engineers and researchers to join us on this epic quest.Responsibilities:Write SOTA GPU kernelsOwn complex production ML/AI systems end-to-endUnderstand how kernel-level gains translate to wall-clock improvements in productionBuild the infrastructure that lets LLM agents iterate unsupervised for days - compilation, correctness, benchmarking, scoring, lineage trackingDesign the evolutionary search - fitness landscapes, variation operators, population management, selection pressure, stagnation detection, exploration vs. exploitation over multi-day autonomous runsCommunicate and share ideas through high-quality documentation, technical meet-ups and blogsFor lead candidates: Hire and mentor a small team of exceptional engineers and researchers.Qualifications:You've written and shipped high-performance or SOTA CUDA kernelsDeep understanding of mixed precision, quantisation (INT4, INT8, FP8, MXFP4, block-scaled formats), kernel fusion, distributed computing strategies (TP, PP, CP)You've made deliberate choices about tiling, memory access patterns, warp-level primitives, and instruction schedulingYou've traced performance cliffs to their root cause through profiler outputYou've worked with CuTe, Triton, Helion or equivalent abstractions, and know when to dive into PTXYou understand GPU architecture across generations — registers through L2, warp execution, divergence costs, occupancy tradeoffs, what changed between Hopper and Blackwell and why it mattersYou know transformers at the implementation level. Attention variants, KV cache strategies, quantisation schemes, and how they shape kernel designYou've worked with production inference or training frameworks, vLLM, Megatron-LM, etcYou've built performance-critical infrastructure before - compilers, profilers, auto-tuners, or search systemsYou have real intuition for evolutionary methods, fitness landscapes, and what makes variation operators work on hard combinatorial problemsYou're familiar with new or esoteric technical methods such as Neural Algorithmic Reasoning, Geometric Deep Learning, Category Theory, Neuroevolution, Megakernels, or the work of François Chollet, Kenneth Stanley, Jeff Clune, Jurgen Schmidhuber, David Ha, and Christian SzegedyBonus:Open-source kernel contributions (FlashAttention, FlashInfer, vLLM, Unsloth, Liger-Kernels, ThunderKittens)Publications in ML/AI, kernel optimisation or evolutionary methods (NeurIPS, ICLR, CVPR, GECCO or equivalent)Other HW experience (AMD, MLX, edge HW)Familiarity with TileLang, Helion, CuTileExperience building agentic systemsDemonstrated work on KernelBench, Kaggle, GitHub, Blogs, StackOverflow Answers, or any public work that demonstrates deep EA, ML or GPU/HW expertiseHPC experienceThis is a full-time, permanent role.
