Shipping the software that powers Zoox’s autonomous vehicles is an extremely challenging job. As a Software Engineer on the Core Data team, you will help build the foundational systems that capture, persist, move and retrieve the critical data generated by our fleet of robots. Our systems connect real-time vehicle software with the engineering and operational workflows requiring fleet data. This includes making critical data available for development, validation, fleet operations, incident investigation, and continuous improvement of the autonomous driving stack. You will tackle complex challenges involving high-speed data, constrained compute & storage resources, multi-host architectures, and fault-tolerant design. This role combines hands-on implementation and systems-level problem solving with opportunities to influence the long-term architecture of Zoox’s vehicle data systems. You will collaborate across the organization to define requirements and deliver practical, reliable solutions to ambiguous cross-functional problems. In this role, you will: Contribute to the technical architecture and implementation of Zoox’s on-vehicle data systems Design and develop reliable, high-performance systems for capturing, storing, retrieving, and transmitting vehicle data with strict real-time and resource constraints Own complex technical problems from initial investigation through design, implementation, validation, and rollout Collaborate across teams through requirements definition, design reviews, and code reviews Qualifications: Bachelor’s degree in computer science, engineering, mathematics, or a related field and 3+ years of professional software development experience Strong proficiency in modern C++ Experience with multithreading, concurrency, inter-process communication, or networking Strong problem-solving skills and the ability to investigate issues across multiple software and

Zoox is building the world's most advanced self-driving hardware and software solution, and nearly every part of it depends on moving data reliably. Sensor frames to perception, planner decisions to vehicle controls, telemetry to the cloud, and remote operator video back down again. All of it crosses process, host, and network boundaries under hard latency and reliability budgets, on a vehicle that has to keep working when a link degrades or a network gets congested. The Software Core Connectivity team owns that data path end to end: in-vehicle messaging (pub/sub, RPC, inter-process and inter-host transport), the vehicle's internal network, and vehicle-to-cloud connectivity. It also owns the transport and serialization abstractions the rest of the software organization builds on. Every one of those paths crosses a team boundary, so the work happens alongside firmware, product security, simulation, manufacturing, and IT, and those partners rely on this team for transport and networking depth to achieve their goals. As the team leader you will own the roadmap and the release commitments, and you will spend a real share of your time in those partnerships. In this role, you will: Own the roadmap, staffing, and release commitments across the team's messaging, in-vehicle network, and cloud connectivity work. Lead and grow a team of software engineers, run their performance and promotion cycles, and hire into the gaps. Represent the team in cross-functional programs across firmware, product security, simulation, fleet operations, and infrastructure, and build the relationships that keep shared work moving. Set the technical bar. Make the architecture calls stick, and make sure the abstractions the team ships are ones other teams want to build on. Balance interrupt-driven reliability work against long-horizon architecture, and be explicit with partners about the tradeoff. Qualificati

We’re reinventing personal transportation—making the future safer, cleaner, and more enjoyable. We’ve created our vehicle specifically for dense, complicated urban environments.

Our Simulation team builds the tools that engineers across the company rely on to validate autonomous vehicle safety and performance - including 3D scenario authoring tools, generative models for realistic traffic and scenario generation, and agentic tooling that automates manual simulation workflows. The team combines traditional software engineering with machine learning engineers, and the simulation coverage they deliver directly determines how many miles, scenarios, and edge cases we can validate before each autonomy release. We're looking for an Engineering Manager to lead a team of software and ML engineers building the scenario authoring tools, generative models, and agentic tooling that engineering relies on broadly to validate autonomous vehicle safety and performance. You'll own the team's technical direction - including its ongoing shift toward generative AI - while growing and developing the team, and you'll partner cross-functionally to scale our generative scenario creation capabilities as a company-wide capability with executive visibility. In this role, you will: Manage and grow a mixed team of software and machine learning engineers building simulation tools that are used broadly across engineering to validate autonomous vehicle safety and performance. Set and drive the team's technical direction, investing in agentic tooling to automate manual simulation workflows and deploying in-house generative models for exploratory vehicle testing. Lead high-visibility, cross-functional initiatives to scale the company's generative scenario creation capabilities, partnering with stakeholders across engineering and earning executive sponsorship. Own delivery of simulation tooling and services, including scenario authoring tools (e.g., 3D visual editors) used broadly across engineering teams. Ensure simulation tooling keeps pace with new Operational Design Domain (ODD) capabilities and upcoming autonomy milestones.<
