Zoox is looking for a Senior Signal Integrity and EMC Engineer to ensure the electrical reliability, signal fidelity, and compliance of our complex autonomous vehicle systems. In this role, you will own the end-to-end strategy for vehicle-level signal integrity, RF/wireless performance, and EMC. You will work within a multi-disciplinary engineering team to set rigorous requirements and ensure best practices are implemented from concept to production. You will serve as the domain expert on a variety of high-speed digital and RF design topics that bring our hardware to life safely and reliably. In this role, you will: Lead the development, implementation, and validation of vehicle-level signal integrity, grounding, and shielding strategies. Maintain rigorous technical requirements and EMC specifications applied across all electrical and electronic systems on all vehicle platforms. Define and maintain vehicle-level RF performance requirements, establishing specifications for all transmitters, receivers, and antenna systems to mitigate the electromagnetic impacts of physical vehicle installation on wireless communication.

Zoox is building fully autonomous vehicles designed from the ground up for robotaxi service — and as we scale toward launch, our engineering infrastructure has to scale with us. We're hiring a Staff Site Reliability Engineer to own source control at Zoox, serving as the technical lead for the platform that every engineer depends on daily. This is a hands-on lead role. You'll set the direction for our Git-based monorepo, drive a restructuring of our Source Code management strategy, build the tooling that improves reliability and developer workflows, and partner with platform, security, and product teams to make source control a strategic asset rather than a bottleneck. The ideal candidate leads by building — with deep expertise in monorepo management (branching strategies, code review workflows, access controls, CI/CD) and a track record of improving developer productivity through code, not just guidance. You take ownership, measure what matters, and have the technical credibility to make decisions stick. In this role, you will: Own the technical strategy and roadmap for source control at Zoox. Plan and execute a strategic effort to scale source code management at Zoox: scoping, design, implementation, cutover, and validation, in partnership with security, platform, and engineering teams. Build and operate monorepo scalability improvements across repo structure, branch strategy, code ownership, large-file handling, and CI integration — including the scripts, hooks, and automation that make them stick. Develop the guardrails and developer-facing tooling that reduce toil for SRE and product engineering alike, measured by build times, merge friction, and interrupt volume. Set the technical bar through code reviews, design proposals, and pairing — and serve as the hands-on authority for source control decisions across Zoox engineering Qualifications 5+ years operating GitH
