Software Engineer, Wireless Technologies
Foster, CA - USA
Job Summary
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.
Contribute and Develop: Contribute to Zooxs 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 vendors 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.
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.
Hands-on experience in maintaining the Linux Applications kernel code and embedded services including experience porting and patching open-source packages within the Yocto Project environment.
Strong understanding of networking concepts (Ethernet TCP/IP IP routing design VLANs firewalls and both IPv4 and IPv6 protocols).
Working experience in the Automotive industry.
Familiarity with other wireless technologies (Wi-Fi Bluetooth BLE).
Familiarity with embedded interfaces (UART I2C I2S SPI CAN PCIe etc.).
Prior experience collaborating with test teams using industry-standard network emulation tools (e.g. Keysight UXM).
Experience in design develop and secure wireless software systems by implementing robust network protocols and advanced wireless security protocols.
Highly motivated and self-directed. Thrives in a collaborative environment and can clearly communicate complex technical issues to both internal teams and external vendors.
