Staff Software Engineer, Webviz

Waymo is an autonomous driving technology company with the mission to be the world's most trusted driver. Since its start as the Google Self-Driving Car Project in 2009, Waymo has focused on building the Waymo Driver—The World's Most Experienced Driver™—to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Waymo Driver powers Waymo’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Waymo Driver has provided over ten million rider-only trips, enabled by its experience autonomously driving over 100 million miles on public roads and tens of billions in simulation across 15+ U.S. states. Webviz is Waymo's central platform and product for visual debugging, telemetry, and triage. Teams across Waymo (including Perception, Behavior, and Simulation) use the Webviz C++ and TypeScript framework to integrate their domain-specific visualizations into a single tool. The Webviz backend processes and streams 4D (3D + time) time-series logs, real-time telemetry, and simulation data. In this L6 role, you will own the C++ server infrastructure and concurrent data streaming pipelines. You will design C++ abstractions to load and process fleet logs, optimize Borg, RPC performance, and build APIs that let engineers and automated evaluation pipelines analyze driving data. You will:

• Build and maintain concurrent C++ backend services (Borg/Boq RPC servers) that stream time-series and sensor data to the Webviz client.
• Scale C++ data delivery abstractions for offboard storage (CNS, Spanner) and WebRTC streams.
• Optimize latency and throughput using log-sampling, payload post-processing (deduplication, timeline merging), and async C++ services.
• Build backend APIs for automated callers (triage bots, evaluation executors) to render driving scenes.
• Plan technical roadmaps and own the scaling, security, and performance isolation of the offboard data infrastructure.
• Mentor engineers, review system designs, and establish systems-level C++ best practices.

You have:

• Bachelor's degree in Computer Science, a related technical field, or equivalent practical experience.
• 5 years of software development experience in C++.
• Experience with systems programming, including multi-threading, concurrency, memory efficiency, and profiling.
• Experience building high-throughput distributed systems, RPC services, or time-series data pipelines.
• Experience leading technical designs and mentoring engineers on complex, multi-quarter projects.

We prefer:

• Experience with Google-internal infrastructure (Borg, Boq, Stubby/gRPC, CNS, and Spanner).
• Experience developing backend systems for video/image rendering, WebRTC, or developer tools.
• Familiarity with autonomous vehicle data formats (RoadGraph, sensor logs, and trajectory prediction outputs).
• Familiarity with web client architectures (Angular, TypeScript) to design client-server APIs.
• Experience with TDD, performance profiling, and integration testing.
