Embedded Software Engineer, Wireless Technologies

As a Software Engineer on the Firmware team, you will own the software integration, performance, optimization, and debugging of our TCU (Telematics Control Unit). Managing a complex architecture that integrates third-party hardware with our autonomous vehicle platform, you will analyze diagnostics and log outputs across cellular networks, 4G/5G modems, internal software layers, Wi-Fi, and Bluetooth.

You will not only reactively troubleshoot complex field issues but also proactively architect and develop robust host-side connectivity software to handle cellular edge cases and vulnerabilities before they impact operations. Your work will directly safeguard the safety, reliability, and scaling of the Zoox autonomous fleet. Robust, low-latency connectivity is fundamental to autonomous vehicle deployment, powering essential real-time cloud services, fleet management pipelines, and teleoperation capabilities.

By ensuring our vehicles maintain seamless, high-performance connections under the most demanding real-world conditions, you will bridge the gap between cutting-edge hardware, cloud infrastructure, and test systems to enable Zoox to deliver the future of autonomous mobility. You will leverage a profound understanding of how these stacks operate to define the architecture, utilize vendor interfaces, and debug complex cross-layer issues

Responsibilities

• Contribute and Develop: Contribute to Zoox's firmware and cellular wireless connectivity stack (LTE/5G), developing and enhancing connectivity features across multiple generations of hardware.
• Vendor Integration: Act as the primary technical expert working with cellular chipset vendors (e.g., Qualcomm) to integrate their proprietary firmware, SW stacks, and L1-L3 implementations into our custom embedded Linux platform.
• Architecture Definition: Define, architect, and validate the critical software interfaces between the RF-baseband, the vendor's protocol stack (AP), and our host system, writing the host-side glue code (C/C++) needed for the Linux networking stack.
• Prototyping: Prototype and evaluate next-generation wireless platforms for future Zoox products.
• Telemetry and Analytics: Develop the telemetry and analytics platform enabling data collection, analysis, and visualization of data reported from the Zoox fleet.
• Investigate and Solve: Investigate and root-cause issues reported by QA teams and customer feedback.
• Differentiate between host-side bugs and vendor firmware issues using your deep knowledge of cellular protocols.
• Quality and Automation: Support test automation frameworks, collaborate with QA, manufacturing, and other software teams, and drive continuous improvements and best practices within the broader organization
