Harness Engineering’s originator and former OpenAI engineer Ryan Lopopolo (@_lopopolo) announced his move to Google Cloud as Principal Engineer, Agentic Google Cloud Platform.
Ryan Lopopolo is a key figure in OpenAI’s Agent engineering practices.
He previously led infrastructure, payment systems, and developer productivity efforts at Stripe, Brex, Snowflake, and is also the creator of Artichoke Ruby, a Rust implementation of Ruby.
During his time at OpenAI, he published the now-viral article “Harness Engineering” earlier this year, systematically summarizing how to bring Agents like Codex into real-world software development workflows through context, tools, permissions, evaluation, observability, and feedback loops.
This move to Google Cloud signals that Google is bringing OpenAI’s internal Agent engineering methodology into cloud platforms and enterprise workflow scenarios.
Honestly, a shift from OpenAI to Google Cloud is quite rare.
Ryan Lopopolo (@_lopopolo): Some personal news: I’m joining @googlecloud as Principal Engineer, Agentic Google Cloud Platform.
I am excited to chase after building the future of work as part of a cloud that deeply adapts to customer knowledge and workflows and environments.
