William Pietri is a Staff Engineer and hands-on leader with 12 years of experience building high-performing engineering teams and production-grade systems for mission-driven organizations and startups. He combines deep operational chops—shipping MLCommons’ open-source LLM safety benchmarks and running the Wired-covered 1.0 release—with product sensibility from roles at NYU Tandon, ADL, and Code for America. William excels at taking research projects to scale (e.g., the Online Hate Index processing 500M+ posts) and inventing robust data pipelines that tolerate flaky upstream services. He’s equally comfortable reducing cloud costs and improving developer practices as he is leading hiring and cross-disciplinary collaboration with researchers, lawyers, and journalists. Based in Chicago, he brings entrepreneurial grit from founding startups and consultancies together with a long track record of shipping reliable, observable systems that inform policy and public conversation.
