Senior🎓
Top SchoolSean Mccullough is a seasoned Staff Software Engineer with 17 years of experience building production-grade systems across cloud, backend, and experiment analytics domains. Based in San Francisco, he combines deep language fluency in Go, TypeScript, Java, and Python with extensive Google Cloud expertise (GKE, BigQuery, Spanner) to deliver scalable services and data pipelines. At Google he designed CABE, a gRPC/Go service that reduced false-positive perf regressions in Chrome builds by taming multidimensional benchmark noise—saving developer time and compute. He also shipped ML-backed tooling (spam filters, label recommenders) and online experiment infrastructure, demonstrating a pragmatic blend of ML, data engineering, and reliable ops. Now at sketch.dev, he continues to apply generalist leadership and hands-on implementation to hard systems problems. A practical innovator, he often surfaces subtle instrumentation and analysis improvements that turn noisy signals into actionable product decisions.
