Senior Software Engineer, Rust DittoSenior Software Engineer, RustSan Francisco, CaliforniaThat means designing and building the telemetry pipeline that runs inside the Rust core: what we instrument, how we collect and buffer it locally, how we get it off the device, and how we make it useful — both for our engineering team diagnosing issues and for our customers understanding how Ditto is performing in their applications. You'll think about bounded buffers on devices with 2GB of RAM, support bundles that help our support engineers resolve issues in hours instead of days, and remote telemetry that gives us fleet-level visibility across hundreds of customer deployments.
