Summary
Chet Aldrich is a Senior Staff Software Engineer with 11 years of experience building data-driven search, recommendation, and infrastructure systems at scale. Based in Middlebury, Vermont, he progressed through increasing engineering roles at Postmates and Amazon before joining Root Inc., where he now shapes core platform and data systems. He led the ground-up rebuild of Postmates’ search and feed infrastructure, delivering measurable product improvements like single-digit percentage lifts in conversions and deliveries. His background spans large-scale batch and streaming pipelines (Apache Beam, MapReduce/Dataproc), backend services in Go and Java, and experimentation-driven product work. Colleagues describe him as a pragmatic problem-solver who combines metric-focused engineering with thoughtful production optimizations. Outside of product metrics, he has a track record of reducing operational costs and runtime (e.g., 37% faster ad forecasting jobs) through targeted performance and memory optimizations.
