About the role
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.
What they're looking for
- More than 10+ years of experience in embedded linux systems and cellular/wireless stack software/firmware development
- B.S. or M.S. degree in Computer Engineering, Computer Science, Physics, Electrical Engineering, or equivalent experience
- Exceptional programming skills in C/C++, Linux OS, and Python/Shell scripting
- Deep architectural understanding of LTE/5G Protocol Stacks (NAS, PDCP, RRC, RLC, MAC, PHY) and 3GPP specifications
- Proven experience successfully integrating third-party cellular modems and proprietary stacks, with hands-on experience using Qualcomm ecosystems and cellular network analysis tools (e.g., QXDM , Shannon Tools, Wireshark)
- Good understanding of Embedded Systems, OS concepts, computer architecture, data structures, and algorithms
More about this role
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.
