Joshua Marple is a Senior Software Engineer with 12 years of experience building high-trust data platforms and diagnostics used across Google products like YouTube, Search, Workspace, and Maps. He architects scalable, high-QPS ingestion and analysis systems, notably replacing a brittle ring-buffer stack with a horizontally scalable platform and cutting Spanner query latency 22× to enable adoption by the highest-load teams. As a tech lead he combines hands-on rewrites with measurable team improvements—doubling feature velocity, halving deployment risk, reducing codebase size dramatically, and improving MTBI—while codifying incident response and on-call practices. He also navigates privacy and compliance at scale, using statistical proofs and differential privacy to secure longer-term analysis without per-user tracking. Based in San Francisco, he’s open to Tech Lead roles where the data layer is integral to product.
