Staff Software Engineer, Webviz
About The Position
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.
Requirements
- 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.
Nice To Haves
- 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.
Responsibilities
- 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.
Benefits
- discretionary annual bonus program
- equity incentive plan
- generous Company benefits program
