Cody Wild is a Research Software Engineer with 11 years of experience building production-grade ML systems and research tooling, currently contributing to DeepMind on Jax-based modeling and prompt-tuning for large language model workflows. He combines a strong research pedigree—from co-authoring NeurIPS and ICLR work at CHAI to first-author preprints on layer-dependent sparsity—with hands-on systems work like a Flash-Attention variant and an autorater that cut human disagreement dramatically. Cody has driven modular, reproducible frameworks in both PyTorch and Jax, led engineering for NeurIPS BASALT benchmarks, and contributed testing and pipeline fixes to notable open-source projects such as Overcooked AI and MineRL. Based in Oakland, he’s equally at home automating robust test suites and probing representational learning questions, and he often bridges the gap between exploratory research and scalable experiment infrastructure.
